Shorted caps on the main board - possibly liquid damage

What's up, iFixers :)

Found an old Asus Transformer Book T100TA laying around at home today - it belonged to my relative back in a day.

Tried to turn it on and it won't - only the amber LED next to the power button would blink.

Wen plugged into charge the device would take 1,76 A out of 2 amps that USB port could give

After a while battery gets insanely hot, so I disconnected the charger. Device still won't power on anyway.

At this point I decided to have a look inside - someone definitely been here before me - half of the screws are missing and I found that all of the caps I marked with red are all shorted to ground:

At the same time the caps I marked with blue are not shorted.

It could be a result of a liquid damage, because I found way too many traces of that on the keyboard, but could not really find anything obvious on the main board.

Just wondering what might be the cause of the short and if it's reasonable to fix the device just out of curiosity

Update (09/14/23)

So for the sake of convenience here are the images of the board on both sides:

And once again - I found that caps in the red area are shorted to ground and the ones in the blue are not:

And today I also found that these caps I marked with red circles are shorted, so I believe the problem could possibly be one of them.

Since I'am an absolute noob I have zero clue for the following:

  1. If I'am on the right track and one of those caps is the issue - which one should I remove first to see if the short is gone
  2. What might be the value of those caps and where do I find a replacement
Answer this question I have this problem too

Is this a good question?

@insympathy this "After a while battery gets insanely hot" would actually be more related to the battery then the charger. Your battery control board should cut of the charge before your battery gets to that point. I'd replace the battery first.

We would need to know what make and model your motherboard is. That way we could try to figure out what happend. It had to be major in order for all of those caps to be falsely connecting to ground.

Hey, thanks for the hints!

I disconnected the battery and that didn’t change anything, so the problem is somewhere else I believe. Btw after disconnecting the battery the device kept draining around 1,5-1,6 amps.

As for the motherboard- it’s a “T100TA Main Board Rev 2.0”

I updated the question with some of my today's possible findings - hope that makes any sense :)
