The battery plugs directly into the logic board so there's only three components to the hardware equation: It's unlikely a firmware issue and there's no battery board on the MacBook Air. It's quick and easy enough to do if you wanted to give that a go. An archive & reinstall of the OS would eliminate the OS and software from the equation. Truthfully it's difficult to pinpoint those specifics. Macbook Air 2,1 - 1.6Ghz - 2GB DDR3 - 128GB SSD - 10.6.8 Snow Leopard Been on 5 minutes, battery at 95% and saying i have 3:31 minutes remaining,

I am now using it on battery power to see how it is. Is the problem with the battery ? SMC ? Software ? Then i unplugged the magsafe and it is now saying the battery is Normal86% health and has 4395Mah. This morning while still plugged in it said 100% and fully charged but remained saying Replace Now. I switched off and reset the SMC and restarted.Īnyway i kept using it while plugged in and then put it to sleep and left it charging overnight. I used a bettery meter program and it said the battery was bad (9% healthy) and only 1300MaH. I plugged in the adapter, took it out of sleep and the battery was 0% and saying Replace Now. I was sure the computer had around 45 - 50 % battery when i closed the lid an hour or 2 before and when i opened it the mac went to sleep after a minute.

Once it charged fully it was reporting as Normal.Īnyway yesterday same thing. I plugged in the charger and took it out of sleep and the battery indicator was saying that the battery must be replaced now. 2 days ago the battery in my Macbook Air got to 0% suddenly and went sleep.
