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!

Once you get a new battery in there reset SMC:

No PRAM battery in these machines. Replace your battery with one from OWC:

"3. Super slow in all operations."
How much RAM? Think about putting in an SSD from OWC.
Here's my early 2011 13" MBP w/ 8 GB of RAM and a 120 GB SSD running Mavericks (10.9.5).
