Will a battery replacement fix my MacBook Air
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?
I would like to hear to what solution you have got.
Got a similar Problem. Waterdamage is about 2years ago. Mac only running with power supply. Its lagging like !&&*. The SSD passed the test and i got the same Hardware Error like yours. Would like to know what you have done to get it to work
