The computer consumes 20v and 1a, so it's normal consumption, but I have no display and the battery is disconnected. I tried the chassis and it's fine. I put a another motherboard and everything works.
LA-300: 1.35V ok
LA-350: 0.9V ok
LA-640: 0.9V ok
LA-650: 0.9V ok
L-7330: 1V ok
L-7231: 1V ok
L-7221: 1V ok
L-7211: 1v ok
So the CPU VGA is powered and it heats up.
We found oxidation on UA-600. I deoxidized it, but the same thing happens.
I replaced UA-600, but the same thing happens.
