Trying to fix an Edge 13

Hello I am trying to fix an Edge 13 0197-2au for a friend. Not sure if it's the motherboard or not, but here goes. When I press the power button, the red thinklight comes on, but does not boot until I have turned it off by the power button and try to turn it back on after 10 to 15 tries. Once on it runs fine with win.7 and does not get hot or anything like that. Now when I try to restart through windows, the display turns off, but the red thinklight stays on and the fan keeps running, so I have to hold the power button down to get it to turn all the way off and I have to go to the above process again to get it to boot. I have tried taking out the battery and pressing the power button 10 times and holding it for 30 seconds. I also tried to reseat the ram, remove the ram, disconnect the wireless card, removing the hard drive, unplugging the cmos battery and the key board as well all to no avail. If is relevent, the battery seems to charge fine and does so once booted. I have the latest bios and ati drivers installed. It has the L325 Amd processor. Sorry for all the rambling, just trying to go through all the steps. Any help and suggestions will be greatly appreciated. Thanks in advance.

 

No possible ideas?

 

Oh well not sure what it is. May be the graphics card. It seems like it has to warm up before it will boot. I will just tell him to part it out.

 

I'd try pulling everything again and doing the power button thing again. Try to power it with the AC and see if it beeps. If not, it's probably the board. That seems like the best candidate, but honestly, it could be anything. I've seen all kinds of strange things make PCs not boot.

 

Thank Zaz.. I will try again when I get home. It does boot, just not on the first several tries. When turned on the red light comes on and the fan runs very slow. I can feel the hard drive spinning, but no display at first. It also starts to get warm on the bottom right where the exhaust is. Once warmed up it will finally boot up normally and runs fine. All the ports work as they should, even the port that charges when the notebook is shut off how relevant that is I'm not sure. It's just weird how it has to be warm to boot normally. Keeps me thinking it may be something simple, but at the same time I keep thinking it may be the board, not sure. Oh yes Zaz once it warms up and boots, it will beep if I remove or insert the a/c adapter. Not sure if thats exactly what you mean. At least now when I shut it down, it will power all the way off without pressing the power button unlike before I had to press and hold he power button to power it all the way off. Weird I tell ya LOL

 

Well as weird as it may seem and the fix may only be temporary, I took it back apart and since it would only boot when warm, I started messing with the heatsink and after a few minutes I decided to loosen the screws that hold it down just a little and low and behold it works. Powers up every time, shuts down and restarts from windows as well. Not sure why that was the case, but has been working fine the last 3 hours no problems. I am posting this from it as well. I will keep my fingers crossed to see how long it works.
One more note. According to speedfan, the temps are lower as well now. Was idling in the 70C range before and now as I type this, it is around 50C.

 

Well that only lasted a day lol. Back to the drawing board. It still starts, but it has to get warm first.

 

I finally took everything apart including the motherboard, took off the heatsink and replaced the thermal pad with paste, blew out the vents and fan. They did not look bad, but blew them out anyway. Put everything back together and the results were the same for a day. All of a sudden, it started and shut down like it should for 2 days now. Puzzling to say the least, but for now everything is working fine and temps are still pretty good as well.

 

Persistence pays off in this case.
