Hi,
I have a late 2008 (2009?) Macbook Pro that I bought used. It worked fine hte first year, but the battery slowly started getting worse and worse, until it would only last unplugged for maybe an hour before it got drained. So I purchased a new battery.
I installed the battery without any problems and the 'Service Battery' message is gone. The battery says normal, see below.
If I unplug the charger, the macbook will keep working, nothing weird happens. But usually after 20 mins or half an hour, it will just turn off with NO warning. There is no warning for low battery either if it happens to get down near 10-15%, just black screen. Laptop starts just fine once plugged back into the wall. The time it takes to turn off varies.
WHY IS THIS HAPPENING? WHAT can I do to fix it? This is a brand new battery.
