I bought this 2 year old laptop used about 2 months ago. Vista home was the os. When I bought it I knew there was an error on it about the time clock stopped. I took it to a repair tech and he replaced the cmos battery and checked it out. Everything was working great. A week ago it starting just shutting down. It shuts down 30 seconds after you turn it on or 30 minutes, it don't seem to matter how long it has been on. I took it back to the tech and he said it sounded like a heat problem. He blew out the heat sink and fan. still it shut down. It shuts down when you are on battery power, it reboots when on ac power.When the battery gets low and you need to charge it, it shuts down when you plug in the ac power. I was told that if it shut down while in bios it was the heat sink. It shut down in bios, so I replaced the heat sink. I was told it could be graphic drivers, I checked all of those and they were all good and up to date.I was told to restore the laptop, I did and no change. I was told to restore with a different os, I did and no change. It now has xp pro and still shutting down. It usually stays on abot 5 minutes. It has stayed on as long as 8 hours. When I restored it , it stayed on long enough sometimes to complete, there were times I had to start over.
I was told to take the battery out.Hold the power button in for 30 seconds. Plug ac power in with battery still out. Then put battery back in. Still no change. The tech replaced the wire loom in front of the laptop because none of the operation lights work. The 4 lights in the front that tell you if you are charging,hard drive activity, etc. Replacing did not fix the lights. Also did not fix the shut down problem.I hope to find the solution. Thank you for your time.

When you replaced the heat sink did you reapply the thermal compound that goes between the CPU and the heat sink?

Try this, start up using the "AC" power, go to Start> right click on My Computer> Properties> Advanced> Startup and Recovery. Under startup and Recovery click on Settings, uncheck the box in Automatically restart under System failure.

This will cause the computer to display an error rather than rebooting. Please copy the error message exactly and post it back here.

Another possibility is that this could be RAM related. To ascertain if this is a problem download and run Memtest86. You will want to use the "ISO image for creating bootable CD (Windows - zip)".

There is a tutorial for using Memtest86, you can read it here.

Thank you dc for your response,

I did reapply the thermal compond.
The do not restart is already unchecked.(which seems to be more of a power failure than a reboot now. It does ask sometimes if I want to start normal or safe mode after it shuts down.
All memory tests passed. MEMTEST86 and the dell diag.
It seems to not like ac power. As long as it runs on battery it seems to do better. When I plug in ac it shuts down. It is more of a power failure than a reboot.

Thank you

Also could you point me to acceptable levels for the adapter if any of the above is possilbe.

Thank you,
