Therix30
Newbie level 2
Hello i'm Riccardo from Italy, i'm a IT technician and now i'm trying to prepare myself for chip level repairing.
I've a lot of laptop mainboard not working, so i decided to do some practice with those. now i have a compal icw50 and the problem is that it continues on power on and shut. i'm working with only the mainboard, no cpu no ram no vga, but the problem is the same. i've tested 3 and 5 always power and cpu power and those are ok, i've searched for short on inductance and ground but i had no success... what can be the next check? or have anyone any idea on this maybe stupid problem?
thanks a lot,
Riccardo
