[blazerazor]

This laptop wont boot at all. I wont even blink lights. The guy who who gave it to me said the lights used to blink when he hit the button, but nothing else.

Any ideas guys??? By the way, Its a Sony pcg-fx140.

Update, I get solid flash of lights. then the power lights stays on. (I fixed a fowled up ribbon connection)
