Cassandra: 13" MacBook Pro with Retina Display - Recurring Battery Problem
By Graham K. Rogers
Over the last couple of days I have been debating what to do next, while at the same time trying some steps to make it disappear. In the meantime, I wrote to the developer of Battery Health in case there were a conflict with this new Mac. The other Mac this is installed on shows no problem.
It is persistent. The last thing I want to do, from a practical point, is to make a visit to the service agent as that may mean a loss of use as it is taken away for "checking" for a number of days or more.
I had already stopped running the Battery Health App, but that made no difference; so when I went home, I deleted the app. I have no evidence to suggest the app has caused a problem, other than coincidence. I also reset the PRAM (parameter random access memory) in case there were something there that might make a change. All in vain.
I recharged the battery and left it on charge for a couple of hours, before disconnecting the power supply; but there was no change. The charge shows 100% until there is a drop to a real 70%, and the warning triangle remains: Service Battery.
There are some more which were in some articles I put online when I last wrote about key commands in December 2011:
