I have a MacBook Air with liquid spilled through the keyboard. The system seems to run fine as long as it's plugged in. The system is unresponsive on battery power alone and the battery reports "Needs Replacement" and shows a constant 15% charge.
A hardware test shows a failure of "4BAT/1/40000000 0x898f3790"
Will a new battery fix this problem? Or does it need a new logic board?
