I have a Macbook Pro mid-2010 (Macbook 7,1) that is acting a bit weird. The battery status always says I'm connected to a power source even when the charger is unplugged. The battery still discharges, but the battery status says I'm connected to a power source. The exception is when I'm at the login screen, where the battery status displayed in the menu bar will be correct.
What I have tried to do:
- Done a clean install of Mavericks
- Reset SMC
- Reset PRAM
- Reinstalling the battery
- Using another charger
- Boot from my Macbook's original HDD
But to no avail.
Additional information: I just got my Macbook back from repair where they changed a faulty logic board. I have an Optibay installed where the CD-drive used to be and I have upgraded to 8 GB RAM. For the last 1-2 years I've been getting the "Service battery" in the battery status, but I have never had any issues with the battery before.
What do you think might be causing this, and how can I fix it?
