My macbook pro 2011 charging indicator is acting weird. Help please?
A few weeks ago my on screen charging indicator started acting funny. Normally it takes my macbook around 2 hours to charge fully. However, sometimes the indicator says anywhere upwards of 4 hours. Furthermore, sometimes the indicator keeps switching back from the charging symbol to not charging. Why is this happening? Here is my power info:
