WTB: dell 600m parts

I’m trying to fix a broken dell 600m.

I get the power LED for about 5 seconds, then its off.

I have read that it could be a seconary board that has the power buttons
on it.

Does anyone have one I might try before spending the $20 on ebay.
(yes, i’m a cheap bastard)

I have also tried removing and/or reseating everything possible.
(drives, RAM, etc…)

thanks.
