The computer has spill damage. Everything seems to work other than the fact that the battery will not charge. I installed a new battery. That battery had a 44% charge out of the box but dropped to 1% where it stays regardless of how long I keep it plugged in. Like I said it works fine while plugged in and it worked fine off the new battery while it had its original 44% charge. Any ideas? Main board, I/O board?
