Battery meter on Macbook does not update unless I toggle percentage on/off
So the topic says it all. The battery meter on my Macbook does not update unless I essentially force it too. I have to toggle "show percentage" for it to update at all. If I plug in the power adapter the lightning bolt does not appear. Nor does it change the power source to say "Power Adapter". If I toggle "show percentage" it appears and changes the power source as well. If I have the percentage showing it while using my Macbook it never changes; unless I toggle "show percentage" off and then back on.
Edit - It also shut down in the middle of watching a movie today. No low battery warning at all. It said it had >50% remaining and then just shut down and started telling me to plug in the power adapter. Yosemite v10.10.1
