Computer keeps shutting off without warning

Specs: Windows xp sp3
I have a IBM Lenovo N100 3000 laptop that keeps shutting down at random, it doesnt matter what you do it shuts off when it feels like, what i notice is if it is off for a while it will stay on longer before the first shutdown but once the first shutdown occurs it just keep on doing so as soon as around 5 minutes after bootup.
I thought it was having a heat issue so I opened the section where the fan and processor heatsink is and cooled it manually with an external fan, i actually had my hand on the processor heatsink one of the time when it shut down and it was extremely cool.
I reformatted my hard drive and installed a fresh copy of windows...same problem
I went into BIOS and left it there to see what shut right off just the same!!!
(I also noticed in the BIOS there is no power management nor temperature readings even though I have ruled out overheating previously I would have loved to see these settings)
so now i'm down to definitely a hardware issue!!
I replaced my memory to see if that was the shuts down just the same!

oops my battery is no good so I wondered if that was the influence so I removed the battery completely and booted it on just AC shuts down just the same!
Could you experts please kindly advice me of what other possible hardware could be causing this problem?
I have tried my best, I really dont know what else to do.

AC Adapter.

- You could have a bad RAM or loose RAM.

- You could have a compnent level failure with something on
the motherboard.

- Also, check this post out by RAZZI: could be the Energycut software shutting it down.

If it shuts down in bios that isn't a good sign. It at least proves to some extent that it is a hardware issue.

See if bios shows health settings for power or heat. It might provide a clue.

Try making an ultimate boot cd and running some of the tests. One might be memtest. As you suspect heat and power also play a role. Laptops are harder to diag that desktops, not easy to swap parts or remove parts to test.

Might end up being easier to just junk it and get a new one.
