I wrote about a broken Dell laptop last month and have narrowed down
the symtoms a bit more. Strange that it will boot when you do not turn
it on for a few days.

Dell laptop; battery, cd drive, hard drive have all been removed.
System simply turns on the green light, hums for 1 second then green light
(i.e. power) goes off and it recylces the process. If I leave it plugged in
this cycling will just continue. The screen is just blank.

However if I don't touch the PC for several days and let it discharge?, the
system will boot off a floppy, function for a few minutes then it will lock
up. When you then try to boot it goes back to the cycling issue discribed
above. Nothing.

Does this sound like the motherboard is dead? What would cause it to boot
once or twice when the system has not been used for several days?

Bad power supply. Allow it to cool down for a while, then it will give
enough juice to run your laptop for a short while. Heats up even a little,
and then it isn't running as efficiently. -Dave

If your laptop has one of those "brick" type external power supplies, that
is what I would suspect is causing the problem. -Dave

Yes it does have a brick like power supply but I have tried it with 2
different ones and obtain the same results. Within 30 seconds it heats up
and locks up. After which it does not boot at all????

Appreciate your help.

Whoa. Ummmmm . . . in that case, I'd wonder if the CPU cooler is clogged
(dust) or if it has died? -Dave
