I've got a Dell 600m that has gone tits up, and I've exhaused everything I can think of.

A month or so ago, the power swtich started having issues where you'd have to press it just right to get it to turn on. I didn't think too much of it, figuring I'd replace the switch when it finally went. Fast foreward a few weeks, and the computer starts refusing to turn on. Now, every once in a while it'll turn on a boot and work for at most 5 minutes before shutting off. Once it's shut off, it'll only manage to blink the LEDs before turning itself back off. No about of unplugging or resetting will fix this. It can die anytime in the startup process, weather the bios has finished loading or windows has finished loading, it doesn't care. At one point the bios gave an error about shutting the computer down because it had been too hot, but it hasn't given that error since the first day it really died.

The odd thing is that the power switch itself is fine. I swapped it out, figuring it would help with debugging, but a new one works just the same, and the old one on the other laptop works fine.

So at this point I can only conclude that the power supply is dead. Of course, seeing as the power supply is on the motherboard, there doesn't seem like there's much I can do besides replace it. Rumor has it that will cost %650, and seeing as new 600m's cost $750, I'll probably replace-and-harvest if I go down that route, but I really would prefer not to.

Is there anything I can do to fix the power suplly myself?
