TBH I´m not quite sure. DC jack is missing because it was shorted I was told. However, I measured it to be ok (160 kohms), but resistace to ground on some coils are suspicious. They might just be high current rails, but I figured I could see if anyone had the schematic while I wait for a new DC jack.

I finally got a new dc jack, charger and battery for this thing. I put it together and nothing. Measured voltage on the coils, but couldn't find anything except for rtc battery (3v), dc jack (19,45v) and one bios chip had 3.3v on about half the pins. I would really like to get the schematic if anyone have got it.

Ok, I have searched for the schematic for this now and then, and now I finally found it!
No 3v or 5v and shorts to ground on both lines would make me think that tps51125 is faulty, will desolder pl5 and pchoke6 to confirm.

Can anyone tell if there is an equivalent to apm4910kc-trg? This is definately broken.
