Which battery shall I replace?
My macbook pro model is A1278 (13 inch, early 2011). The battery condition is shown as "replace now". And there are a few more symptoms:
1. When connected to power, it automatically starts up.
2, After start up, time is reset to Dec.31, 2000.
3. Super slow in all operations.
I wonder if it's caused by a dead PRAM battery or just the commonly referred battery?
Thanks in advance!
MacBook Pro (13-inch Early 2011), OS X Mountain Lion (10.8.5), null
