Having problems with your PC Laptops ?

I have a Sony laptop VGN-CR240E/B thats 6 months old. It has an intermittent problem. It works great when it turns on. When it does not turn on, I only see the power button light and the battery light turn on and then it goes off. nothing happens, or I get the power light, battery light, SD light and the memory stick duo light constantly ON with no screen. I have removed the battery, the power supply works. I have eliminated the memory, hard drive. I dont even see the bios screen/ startup screen


Answers :

Have you tried to remove the battery and work off 100% AC power? Sometimes a faulty battery can cause a laptop to not boot correctly.

But, yes that does sound like a motherboard issue. The only thing you can really look at if your have already checked memory and hard drive is overheating. It is possible a fan has slowed which caused the board and CPU to over heat. This would explain why it works after letting it sit for awhile. I would try keeping an eye on the temp of the system and check for spikes. There is also a small chance the CPU could be at fault if over heating is ruled out. These types of issues are hard to troubleshoot once you eliminate the easily removable parts and get down to the CPU or motherboard.

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.
