Have this in for reballing. After reballing NB it shows video but powers down by itself after 10 seconds if the keyboard is connected, 6 seconds if it is unplugged.
It used to shut down before reballing too, when it was showing no video. It gets to BIOS if i am quick enough, it will even boot from the HDD.
It also turns off by itself with no RAM, even with no CPU. Exactly same thing in every situation, shuts down after 6 sec without keyboard, 10 sec with keyboard. Regardless of everything else. It will stay on maybe 1 second longer if i'm mashing the keys in the meantime.
I would replace KBC. In fact i would've already done that, just that i didn't have one handy and we'll have to order it. Any other ideas? I have a 100MHz digital oscilloscope to use now.
