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?

  • It came like that after logic board replacement? it did not do that before? The Service battery is Normal and nothing to worry about once you hit 30% below the Design capacity (your case). Once it shows Replace battery NOW then you act.

  • Try starting in safe mode to see if the problem is still there. Check the Middle pin (of the 5) for the magsafe plug and clean it.

  • Middle pin on the Magsafe on the charger or on the Macbook?

  • On the Macbook, since it shows it charging even if no charger is connected. That pin is responsible for that. Safe mode to eliminate 3d party apps.

  • The problem was not fixed by booting in safe mode. I tried cleaning the middle pin with a dry soft cloth, but to no avail..

this is how i fixed mine. I went to "energy saver preferences" in "system preferences", and went to "power adapter" at the top, then i clicked "show battery status in menu" option off then on again and that seemed to work for me.

Hope this helps!
