i got the 3.3 and 5v supply before it turn on.

i can't get those voltage bcoz of it turn off quickly. but one time it takes a bit long stay on so i got those voltage it has 1.5v and 1.0 v some of them.

Re: asus x53e weird issue.

u need to check all woltages on coils right after start. check for rising voltage. if no rising, than there must be short

but i think u need to reflow od northbridge

On the picture i still can see the wlan card still connected to the board, remove that and try to fire it up.

Re: asus x53e weird issue.

take the bios bat out and discharge the board!(i mean let the battery out)

why do i think it will power up by it self?!?!?
