Hello, I have an ASUS Q304UAK laptop. Recently due to an unfortunate incident, some water spilled on it while it was inside my laptop bag. After taking it out and when it did not turn on, I opened the back cover and could see traces of water under the battery (after removing it). I dried it with hot air and then replaced the components. The laptop boots through AC power but doesn't work on battery (as soon as the ac cord is removed, it shuts off). While plugged in, it shows plugged in, charging but it's stuck at 87 %. I downloaded Battery Bar, a utility to check battery health and charging details which shows the Charge Rate as 0 mW. I am wondering what could have gone wrong, is it the battery (hopefully since it's cheaper to replace) or the motherboard?
