working on this t4510 emachine that started out with a bad psu
or so says the client. psu
is definitely bad according to my psu
tester. have a new psu
that matches the original psu
and my tester reflects its working properly.
problem - when i first plug the power cord in cpu
fan spin up as does the psu
for just a second then stops. if i switch to another power cord again the fan spins for a sec then stops. have disconnected every thing from machine including removing memory module. have receded every thing have removed the push button control and manually pushing the switch in still no consistant power. this is a new psu
and again it does test out just fine. hocked up another psu
with the same power connector and p4 connector and i get the same results. fans spin for a sec. then stop. thought maybe the switch but dont think so now.
looking for possibilities. i think the board has just died but not sure. being client said they went away on a trip and when they came back and turned machine on it wouldnt boot. am thinking that they took a big hit while they were gone which blew the psu
