I managed to find the fault in the EC. I reprogrammed it 4 times because every time I did it and turned it on, it would die again when I disconnected it. Finally, it works....

i try not work

no power on
no led on charger...

hello ec? dump

Hi, I received this motherboard and I've checked it and I'm finding 19V everywhere. At the power button I have 3.3V with no sign of life; when I press the power button nothing happens and there's no current draw. When I connect the battery it doesn't charge. At PL15 and PL16 there's neither 3.3V nor 5V. I've measured and there's no short to ground. Any idea what it could be?

hello i need help
the laptop no turn on
when i press power on nothing
no led on charger
i test all voltajes is present ok

Hi, I have this motherboard. The problem is that two MOSFETs on the video card burned out due to water damage. When I replaced them, it worked, but then stopped working. I checked and one of the MOSFETs on the processor isn't active.
I'd like to know if it's the processor's integrated graphics.

The motherboard turns on but doesn't provide video. I've already reprogrammed the BIOS and it doesn't work. Any ideas?
I couldn't find a schematic or BoardView. ...
