It may happen sooner or later between 1 min to hours after boot. When the laptop stops working, kind of noise is seen on the LCD as if there is a mobile phone beside a monitor. And when I push the heat sink, the noise disappears but the laptop stays freeze and I have to turn it off and on again.
I have a toshiba satellite m65 that has been having touch pad, cursor, and mouse problems. My usb ports starting shutting down when using a wireless mouse, then computer started freezing up when working hard several windows open with video running. Downward pressure on the keyboard worked for a while to unfreeze the laptop, but progressively getting worse. It turns on now and fan runs for a couple of seconds, but will not boot up.
That sounds like a problem with the motherboard to me. Try removing memory modules one by one and start the laptop with each module separately. Can you start the laptop with only one memory module installed? I need your help…. The only difference is, when i connect the power cord the battery LED flashes for 3 seconds and then stays on……however, pressing the power ON button does nothing……..
The battery was dead from 6 months and i running it on power supply……. I have a Toshiba Protege R laptop that will not boot up. There is a black screen and the laptop does not boot up. I have checked the hard drive in another R and it works fine.
I have removed the battery and the memory but the laptop still will not boot, no beeps either. Any help would be appreciated…. Have you tried replacing the memory module with a known good module? By the way, very few laptops give you a beep error when there is no memory installed.
The only difference is, when i connect the power cord the battery LED flashes for 3 seconds and then stays on…. Is it normal for the battery LED flash on the startup? Did it flash before the laptop failed? In IBM laptops the power button is a part of the keyboard. Maybe the power button is bad? Can you remove the keyboard and try reconnecting the keyboard cable to the motherboard.
Maybe the connection got oxidized and the keyboard cable is not making good connection with the motherboard. I would try reconnecting the keyboard cable first. I reseated the battery and it came back on. Stayed on and failed again after I powered it off.
Now it wont turn on anymore….. This is the type of article I was looking for… Wanted to test a mobo outside the casing. This gives me visuals on how to do it. Recent purchases the laptop was running fine, without any problems before I replaced. Two weeks later, I have these problems, and the laptop dies…. I replaced both the battery and the power supply.
The power supply was 3. Turn on power, fan, lights come on, then after 5 seconds, it shuts right off. No POST, or ability to get into the cmos settings. Took out the memory, and other easily removable externals. No change. Would it be the battery? I would really recommend using the right type of the power adapter. If the laptop requires 19 volts, you must use 19 volts. The amperage should be the same or higher. Have you tried removing memory modules one by one? I have a Toshiba A60 laptop that will not boot up.
This all was acused when i tried to extend a ram while the batery is in the laptop and this might have disabled the original RAM which is integrated in the board. Is there any solution to enable the dead ram in the board? Any sugetion would be appreciated….
I have a Toshiba Satelite AS with, 1. When I push the on button, the power light comes on, but that is it…. I have searched invista site and elsewhere but have not found this particular problem listed or a fix…. Do you know where I might find instructions to remove hd on this particular computer? THe last week before this total failure, I had a number of times the computer would be fine and suddenly a blue screen would flash and the computer would reboot before I could read it.
The last 2 times it blue screened if I moved the computer physically. If I picked it up from the floor or desk it would also go blue screen and reboot. I have a Toshiba Satellite SP10, on boot up it quickly showed the boot up screen then the screen went black. The small hard drive light and cd drive lights were flashing yet still no screen. I decided to format the maching using the manufacturers installation discs and all was going well, I could see the screen clearly and as the installation got to 25 percent the screen suddenly froze along with the cd light and hard drive light.
It didnt respond to ctrl,alt. When I have tried to turn it on since I it takes about 10 hits on the power button before it responds yet the screen still goes black and the machine seems to hang in limbo. I realise the format wasnt completed but why would the whole machine just go to sleep like this. It had a new hard drive installed 12 months ago and showed no signs of illness before it fell into this coma,.
In my case the fan and hdd spin up for about 5 seconds and then shut off, but the power light stays on. I have a 6 year old laptop — a HP zeca. I figured it would die eventually. I took it in to get it looked at and when I went to show them what was happening, it started up!!!
So I bought an external hard drive and quickly started copying my files off of it. I stupidly also had my camera plugged into the USB port and after an hour the whole thing shut down completely kind of like a short circut maybe? Actually the LED light was flashing for a few minutes before it too went off. I would love some ideas on what to try next — taking the battery out, or the memory, or freezing the thing? Does it sound like the Motherboard has finally died?
Thoughts welcome, thanks in advance! My laptop power light comes on for about 3 seconds then off. I replaced a power cord about 3 months ago. I will try some of the things that I have read on your site when I get home today. Thanks fro having a place to ask quetions. The toshiba above looks to be an M30X or M35X series, these are notorious for no video on bootup. The Northbridge separates from the board.
Easy fix with a reflow tool. Computers that are working and say power is connected is a dc jack problem. Also can be fixed with a reflow tool. Every other issue with motherboard is completely repairable. How many people know how to use the reflow tool?
Maybe you can help us and create an easy to follow guide for fixing the motherboard? Secondly,i ve an acer laptop dat does not display ,but it displays once in a while and when it does and i go to bios,it hangs and stops responding. My problem is similar to the one being discussed in this post: When I press on the power button, the laptop starts, the LEDs work properly but noting appears on the screen. I hear two beeps and immediately cooling fan stops but the LEDs continue on, then I have to turn off the computer.
Finally, I disassembled my laptop completely, connect the motherboard to an external monitor and power supply, but when I press the power button, it showed the same problem. Dead motherboard? Let me know if you ever get to the hardcore stuff.
Make sure the laptop is powered down. Set your multimeter to make noise when the circuit is closed. Connect the multimeter probes to the prongs on the switch and press on the button. If the multimeter makes noise when you press on the button, most likely the button is working fine. Do you get any activity from the laptop when you press on the power button at all?
The hard drive noise, DVD drive light, etc..? Sorry, cannot help you. In cases like that I just replace the whole motherboard. Unfortunately, there is no much further testing you can do. It depends on the laptop model. I opened the top part of the laptop, looked a bit, could not figure out much and closed it. After this, it went entirely dead.
Any ideas what could have gone wrong, what to check..? Amazing blog…thank you so much. I was breaking my head over my laptop to figure out which part was causing the problem. Followed your steps and found it was the memory. Thanks Again. I tried turns on again.
Please help me…. Where is the ring lug supposed to go? Thanks much my dear! I have been using your ideas. Let me try the module, no DVD…, bare motherboard and see where I end up. Fantastic blog! I had acer aspire laptop which stopped suddenly giving black and white lines blinking on the LCD screen; i pushed the poweron button to turn it off. Is there any problem with the motherboard? Please Help! Thank you again for the blog. First of all, I would check memory modules.
Remove memory modules one by one and test the laptop with each module separately. Does it help? If not, probably you have a failed video card. In most modern laptops the video card is integrated into the motherboard and cannot be replaced.
In this case you have to replace the entire motherboard. I have a hp laptop. My laptop is toshiba L30, when i press the power button the power LED turns on then immediately goes off, I checked the power cables, the power cable that connected to the mother board is ok, but i did not check the actual DC power adapter output, please help me, its almost dead, i want it back.
When I press the power button, the power and battery LEDs flash then go off. The WLAN light flash as well. I even changed th RAM but nothing works. Any help is appreciated. Great post. I did exactly what you said. I have a Compaq F and the wireless card quit working. Then the video went out a day later. Bought a new mboard. However, when the power is pressed, turns on for about a second, but not long enough to post BIOS.
Do you mean the AC power adapter? It still could be bad even though the battery light is on. Is it blinking because the battery is charging? Can you test the laptop with another adapter? If the AC adapter is OK then your description sounds like a problem with the motherboard. Laptop does not start. Check memory modules, try reconnecting them, removing one by one. Lawrence O Ebare. So I have this laptop, I have replaced the DC power, then the motherboard and lastly the power pack.
It worked with the new power pack for about an hour then died again. Plugged in the old power pack worked for a couple hours then I shutdown but when I went to reboot, nada. The only other thing I can tell you is the battery is completly juiced so it only runs on the power adapter. Any thoughts other then a sledge hammer. The first think to check is the memory module: 1.
Try reseating the memory module. Try removing memory modules one by one if you have two installed. Try installing another memory. On the bottom of the laptop should be RAM cover. Under the keyboard. Reseating the ram did not work, If the motherboard is fried would it still recieve power and show you that the ac adaptor is connected? If the motherboard is fried would it still recieve power and show you that the ac adaptor is connected?
You plug the AC adapter, the light comes on and nothing else. Hi all. What is problem? What the solution? I can help you but I am in Davao City. That is motherboard problem. But no need to change Mobo. You can contact me through skype id: carl. The same problem goes to me but much more worst no boot,no bios and the screen totally blank but it start like normal lptp,i have asusA… give some advise please,. The same problem goes to me but much more worst no boot,no bios and the screen totally blank but it start like normal lptp.
You said the laptop will not boot and at the same time starts like normal laptop. What do you mean? The laptop works with the external monitor and it tells me that your video card and motherboard functioning properly. First of all, try reconnecting the video cable. So, try reconnecting the cable first. I was installing windows 7 rc2 that i got from Microsoft when i found i had a problem with my hard drive. I aborted install and tried to shut down computer, i had to manually remove battery and power lead.
When i reconnected everything the computer would not start up again. I also replaced hard drive but still no joy. Unplug the power adapter, remove the battery. Press on the power button and hold it down for a minute. Now connect the AC adapter and try turning it on again. It is completely dead, no lights or anything. ASUS will not help me either. They said i should not have installed Windows 7 at all. I think i should have left the GB hard drive in as Windows 7 worked a dream, but i wanted to use a larger hard drive.
Thats when the problem occured. Hard drive size is not an issue as i had a GB hard drive with Windows Media. I tried what you said but still no joy. I really doubt that you problem is related to the hard drive replacement or Windows installation.
Can you test the AC power adapter? If the laptop is completely dead and there are no LED lights, it looks like the motherboard is not getting any power at all. Test your adapter or test the laptop with another known good adapter. I think I have the cited MoBo problem, and need your help. Cant access you thru skype. Checked adaptor on spare laptop, adaptor works fine. Connected a known good adaptor and still nothing. Removed battery and checked with Multi-meter and found power going to battery. Checked for voltage on motherboard at a known SAFE location reset button found power.
Removed battery and adaptor and tested reset button with Multi-meter for faults but none found, reset button working correctly. When reset button pressed with power to computer, the power was cut and reconnected when reset button was released. Tested memory on spare laptop, memory works fine. Tested DVD Rom on spare laptop no problems there. I am beginning to think that at some point the Bios has somehow been corrupted, but dont ask me how suffice to say it was not me.
The reason i say that is because in the past when i was new to computers i incorrectly flashed a bios on of all things another ASUS laptop and found to my peril that i had screwed the computer completely. I now leave flashing to the experts, if they screw it up they fix it at there cost not mine.
Looks like i am going to have to replace motherboard after all. Looks like you know what you are doing and unfortunately, it does sound like a problem with the motherboard. Thanks for trying to help, i suspected all along that motherboard may need replacing, but hoped someone out there might have known a way to restart it. I will check back here over the next few days just in case someone posts a possible solution.
Only thing not checked out yet is the Processor, going to check that out. Just a hunch but somehow i dont think thats the problem, but one never knows. Maybe you should try disconnecting the CMOS battery from the motherboard for a while. Who knows, it might help. Not likely but possible. Removing the CMOS battery was the second thing i tried, removed it for 12 hours. After i tried every thing i knew about i surfed the net on another computer and found this site, and crossed my fingers and toes.
Thank you thank you! Who could know the memory sitting well would cause a laptop to look like it had lost the motherboard!! Memory can be a problem because as soon as you turn on any computer the video rom bios address is copied into a set memory address before initialising same as the bootable partition a55 hex. That blinking little cursor tells you that this first procedure was sucessful. Also for this type of problem it can also be related to the laptop trying to boot from a flat battery the smart chip in these batteries is sometimes not so smart.
Voltage regulators on the board can also be a cause. If i boot in normal the blue screen. I have an 80 gig hard drive and one 20 gig which used to be 80 gig. I tend to think this is a bios problem and often wonder if is something with the video but cant put finger on it. Any help from someone would be great that has seen this before. A very models of HP Pavilion have a problems with the graphics chip, in a some web i dont remember a guy puts a video to see how to repair this.
When a mobo is dead nothings bring on. This happened before after a while it turned on and worked fine.. Also at times before I can get it to turn I have to let it heat till the bottom is real hot because even tho it turns on and of after 5 sec. The display was dean on Fujitsu Amilo Pro V and the problem was the memory. When i switch on my laptop led blinks for 5sec and there will be sudden shut down i tried by reinstalling hard drive and ram but no use please tell me what to do next.
Hello, I have a Sony Vaio laptop, it went dead about a year ago, then about a week ago when I was cleaning my closet I plugged it in and it worked fine. Two days later I unplugged it from the wall and ran it on the battery for a bit, and suddenly not working at all.
Well if i plug it into the wall the power light flashes but nothing, if I put in the battery and push the power the light flashes for a brief moment also then dead, this keeps happening each time I undo the battery and plug it in, as well as withe power cord. Any ideas? I just purchased a new board for mx35 s installed left everything out except memory pushed power button came on stayed for 5 seconds cpu fan shuts down lights stayn on and ideas.
I saw some guy use a heat gun on youtube to fix the problem by using a heatgun to blow on the mobo, so it will resoulder the parts together. But nothing displayed. When i contact another hardware vendor he told me ur ROM got faulty and it is not possible to repair or replace it. You have to change the motherboard , which is very costly. The laptop shut down. Occasionally, when the adapter is plugged in there will be a short buzz when I press the power button, but nothing else.
Does this sound like a power surge followed by something on the board frying? Nothing visual. Any help would be appreciated. When I switch on laptop the fan starts and stays on, the battery and power led lights up, the cd drive lights up and stays on but nothing else happens. No hard drive light, nothing on screen. The laptop will not switch of, I have to remove battery. Any help would be great. Hi, i have the same laptop with the same symptoms. I heat the mainboard with the hot air station at the upper right corner both sides, of course and it works!
Seems like that is common problem for this series…. I just want to figure it out. When I set up the screen saver, certain ones will work for a little while if I set them on preview for a long time. What can I do to fix this poblem. My laptop just turned a year old in December. Great guide. Straightforward, simple and effective. Took out a bad memory module and got my laptop back. I have an Acer Aspire series and it shows no sign at all of trying to power up.
The charger is fine but I have tried the charger from another series unit. I get NO lights at all ,no fan , not a thing — except for a very feint, very high pitched sound coming from the centre of the motherboard. The battery is showing 0. I have stripped the laptop down in order to check for obvious signs of a problem, with the charger plugged in and switched on I can find 19 Volts at various points on the motherboard using a digital multimeter. May I ask something??
My laptop will face the problem of suddenly out of power and then restart, although I had put on the battery full charge it still face the same problem. Just suddenly black out like no electricity supply then restart. Sometimes, the computer is hank and the screen is flawad sometimes. I have Compaq HP Nx, its wonderful toy, unfortunately on my power supply cable had s short circuit on the lower-voltage end there was a spark of course my power supply is gone, but the unit stop to response on the new power supply too, laptop is dead with or without power supply, I had 2nd battery as I replaced it, laptop come on but it wont charge nor recognise the power supply connected, i am afraid if charging system got burnt, I am asking is there any short circuit prevention switch on these laptops, otherwise what would be possible damage and how to repair it, Mazhar.
When i power on the laptop fan spins for seconds and turn of! No image on the screen , no nothing. I took out the board and connected on external monitor with good memory module , replaced cpu, power adapter is good no other component is connected. Simptop is the same : turn on by itself , stays on for second and then turn off again.
This board have a Power Button Board on it, maybe there is some short circuit?? Maybe this is common issue with this laptop series? Dont know. Any help appreciated. Sounds like the motherboard failure to me. I doubt this is the power button failure. When you press the power button, the system turn on, right? That means the power button works properly. Again, I think this is the motherboard failure. I am asking is there any short circuit prevention switch on these laptops, otherwise what would be possible damage and how to repair it.
Most likely you can find the fuse somewhere close to the DC jack. When you find the fuse, test it with a multimeter. If the fuse is bad, it has to be replaced. This is just a guess. Does it happen mostly when you move the laptop? If yes, this could be motherboard failure.
Apparently the motherboard has a faulty solder joint or crack somewhere and when you move the laptop, you actually flexing the motherboard forcing it to fail. If the hard drive works while connected to another computer, there still could be a problem with the hard drive.
Maybe it has a bad sector somewhere at the beginning, where all boot files are located. Try reinstalling the OS from scratch. Test your hard drive. Also, check laptop memory. Test the laptop with each module installed one at a time. Thanks for the great article. I was playing a computer game last night l4d and suddenly my laptop turned off. The screen went black. All other appliances work. For some reason, my laptop Toshiba Satellite M went dead. This has never happened before.
I tried turning it back on but nothing happened. The ac power warmed up in temperature as well. But nothing turns on. I cleaned the fan with compressed air to get rid of some dust. As a side note, my laptop would get really hot when I played games and this has been going on for a few months now. I have Dell inspiron laptop with me.
Hi, I just want to give an update on my post that I left yesterday. After I posted my message, I left my laptop with the ac adaptor plugged in. Unfortunately, my laptop began smoking! I unplugged the laptop immediately and have left it unplugged since then.
Should I get a new one? Can I salvage my hard drive? Maybe the AC adapter went bad. Do you have a multimeter? Can you test the AC adapter and find out if the voltage output is correct? After that the laptop worked until the battery had charge and finally turned off. Test the AC adapter first. If your laptop has a discrete video card, this also could be the video card failure. Turn on the laptop and listen for the cooling fan. Can you hear the cooling fan spinning? Maybe the laptop shuts down because of overheating?
I just want to give an update on my post that I left yesterday. It will be necessary to open up the laptop case and take a closer look at the motherboard. The motherboard replacement could be very expensive. Should you get a new laptop? First of all, if you have important files on the hard drive you can recover them using an external USB enclosure. I have a laptop from germany, it fujitsu amilo xa , the mainboard was broken and I had sent it back for repair but the same problem occurred and this time I do not want to go through all this again.
My laptop compaq works fine for few days and suddenly dies. After some banging and cleaning it starts up again and works fine for few days. Can you tell me where the problem lies as i am tired of bang it so often? AKS, When u say your compaq laptop works fine for a few days and suddenly dies do u mean it doesnt startup or crashes all of a sudden???
Do you get a POST screen. Could be memory failure. Test your laptop with only one memory module installed. I tried everything friends. My system starts perfectly but i dont get any display. I have only one memory mudule. After I open it and clean it the system is back to normal. There is no time limit to switch it on. After a little workout the system starts and works perfectly. Please tell me what to do?
Unplug and replug them back again one by one while testing. I watched a video clip on facebook then my screen went blannk would do nothing so I prssed the power button to shut it off then tried to turn it back on and nothing happens. Remove the power cord and battery. Push and hold the power button for at least 15 seconds. Plug the power cord in and turn your computer on. Note: leave the battery out. If successful, shut the computer down, install the battery and reboot.
If not successful, try these steps using the battery and not the power cord in step 3, or try it using both the power cord as well as the battery. If it spots error then its your RAM. Most problems relate to RAM when you get no screen on boot. When did you first notice the problem??? Please be specific for example…Did you remove any hardware, install and hardware, forgot to ground yourself, has is ever been dropped etc. When you clean out the system and it starts working again is that when yuo remove the RAM itself or do you remove other components at the same time???
Hi, I have an HP Pavillion dv which was working fine until some water got knocked over onto it overnight. It was off and not plugged in and the lid was closed, but the battery was connected. I pulled the battery off when I noticed it. There was some water noticeable on the keyboard, but very little. I tilted it and waited before trying to plug it in or turn it on. Now, with the battery removed, when I plug it in, the lights all flash and the fan starts spinning, but then everything goes quiet and it does nothing when I try to power it on.
If the battery is attached, and I plug it in, it just starts charging the battery and nothing else. Do you think this is a motherboard problem, or a power problem? Thanks for your help. I dont have the batery at present,iam using it at home at fixed place,ihave repaced battery one year ago,this problume persist since decmber Then it works smoothly for two three days to one week or 10 days. Just by reading your instructions you seem know almost everything about Toshiba laptops.
I must say that you all are pros! So I had to re solder that put it all back and guess what it powered on. Apart from that the fan also stops in seconds after I turned it on. Test memory. Test hard drive. If both test fine, try reinstalling Windows from scratch. Can you boot in Safe Mode? If yes, try using System Restore and revert Windows back to the time when it was working fine. First of all, make sure the memory module is seated correctly if you have it installed. Remove the external memory module and test the laptop without it there is some RAM soldered to the motherboard.
Minimize the laptop as much as you can. If you still cannot get image on the internal or external screens, most likely you have a problem with the motherboard. Is the memory module the RAM itself? Sorry for these noob questions but I really need to fix it. I just thought you should know this..
The thing is it takes me a couple of restarts then it will boot properly. I have a same problem as Ar. It just happen last night. I unplugged battery and power over night. This morning was working then I turn it off. Same problem again. I de-assembling the whole thing, then put them back together. It works then I turn it again same old story….
The screen gets blurry alot, especially as my wrists are resting on the front of it while I type. Seems to vary with the pressure of my wrists on front of the laptop. If I leave the laptop on for a long time the monitor appears to be fine. But when pressure is applied as I type the garbage returns. Refreshing the screen clears it up sometime. How do I troubleshoot this.
Hi, Thanks for the post. After reading this post I was able to narrow down the problems to laptop. It does not always power on. I did some research and found out it might be a problem with the voltage regulator chip. If so, do you have any tutorial where to find and how to fix this chip? Please help! It is completely dead.
The only thing visible is the battery charge light but the battery died long time ago. I turned on the laptop one day, and it gave series of beeps. Next time I turn it on, it shows the acer screen and then goes dead. Now it remains dead when i push the power button. I read across forums, removed the battery and power adapter, pushed the the power button 45 seconds, put back power adapter and laptop still remains dead.
This notebook HP pavilion DVus will turn on 2 seconds, then off 2 seconds continually until you press a button and then it will stay on but there is a black screen. The magic button, not sure which one I keep pressing buttons until it stays on. What do you think? Thanks, Lorena. Could be failed memory. Try removing memory modules one by one.
The laptop will start properly when the failed module removed. I have a bad IBM R51 laptop. The problem: Can not power on. When I push the power button, the green LED light a moment about 1 second. All smd capacitor shorted, near the processor.
What is the problem? Hi, Great post. As a result I removed the battery. Re-plugged in the laptop….. I have a fujitsu siemens LI, juice was spilt on the keyboard. If you found corrosion on the motherboard, probably the motherboard died. I have an HP G that turns on for 2 seconds, spins the fan and cuts out. Then after 5 seconds it repeats the cycle.
Turns on by itself , runs for 2 seconds and turns off. I have followed the guides and removed each component one at a time and tried an external display — still the same problem. Sounds like motherboard related failure. Just in case try removing memory modules one by one and test the laptop with each memory module in each slot.
I have a g60 us hp laptop. It wont hold a charge and will not power on due to no battery left. Hi, my friend gave me a non working laptop. I have tested the ac adapter and battery and they are okay. After pressing power, the blue light illuminates, as well as the LEDs For battery and plug. The CPU light does not illuminate. If I turn the laptop over I see the fan run for about 5 seconds, and can hear the hard drive run for about the same amount of time.
I removed the memory and saw there was the factory and then a 1 gb. I thought maybe this could be the problem. I tested the 1 gb separate in both inputs, nothing, same thing. I tried with the mb alone and same thing. The screen remains black throughout. I also tried reinstallingthe OS software, but again nothing. Can you please give me any suggestions? Do you think the motherboard is shot? Sounds like a problem with the motherboard. If you have nothing to lose, you can try taking it apart to a barebone system and test just major components: motherboard, memory, CPU.
If the laptop still dead when disassembled to a barebone system, probably you have dead motherboard. Good luck! Hi, I have a Toshiba Satellite AS, when turn on only power light comes on and the fan starts other than that nothing. No turning of hard drive or DVD or key board… any ideas what it could be???
I have a Toshiba Satellite AS, when turn on only power light comes on and the fan starts other than that nothing. Check memory modules. Try reseating both modules. Try removing them one by one and test the laptop with only one module in place. Try different slots. The adapter is working fine, i checked on another computer. I removed all the the parts from the motherboard battery, vga, hard disk, everything. Should i assume for sure that the problem is with the motherboard and not with the power jack?
I replaced a failed motherboard on a toshiba a, with one from ebay. After all assembled correctly what happens is that after post, it shuts off. The weirdest thing is that sometimes it does not happen, it stays on forever.
I am now testing possibilites with only the barebone board and power supply… it seems that if i press with my finger on the graphics card cooler it stays on… and it looks like to have so clearance betwen the gpu card and bolts… any idea?
I am now testing possibilites with only the barebone board and power supply… it seems that if i press with my finger on the graphics card cooler it stays on… and it looks like to have so clearance betwen the gpu card and bolts…. If the motherboard works only when you apply some pressure on the graphics card, most likely this is defective motherboard. Well I reassembled everything and now, with the motherboard off the case, it worked fine for a long time and I did not apply pressure anywhere.
But when I assembled the board inside the case and closed everything it does not work again…. Are you using correct screws? If screws longer than should be, they might short something on the motherboard. Also, take a look inside the laptop case. Make sure nothing shorting the motherboard. I have a HP G With power supply plugged in the power light comes on automatically. Am I correct? I had a chance to boot into windows and flash the newest bios for the board without it shutting off suddenly.
Have you tried reseating memory module? Have you tested the laptop with only one memory module installed? That would explain why the laptop shuts off intermittently. It happens because there is no power coming to the motherboard. But you said the motherboard works fine when removed from the case, it means the jack is fine. Sorry Filipe, I cannot give you a good advice without testing the laptop. The best way to go would be removing everything from the case and start installing parts one by one testing after each step.
Maybe you have one of those HP laptops. Great lesson man this will and u surely help me. Once again great article. I tried reinstalling windows and the audio drivers but it did not solve the problem. Hello, I have an Acer Aspire laptop just out of warranty and it is powering on with fans running and lights displaying but not booting up.
I had the same problem a few months ago and sent it in for repair. I have no clue what to do. Can I reset or flash the bios some way if the motherboard is not dead. I have an Acer Aspire laptop just out of warranty and it is powering on with fans running and lights displaying but not booting up. This could be memory failure. Try reseating memory modules, remove them one by one. Test the laptop with only one memory module in place. Maybe the cooling module heat sink with fan is clogged with dust and has to be cleaned.
Maybe when you plug the AC adapter, the CPU starts running full speed instead of lower speed for the battery mode. Because of that the CPU generates more heat and slows down.

I have onboard video card. Again, thank you for posting i connect the power cord was likely to be found there is a mobile phone.
