If you have the same problem with another power adapter. There is an acknowledged bug in the current version of Cody Kreiger's Open-Source gfxcardstatus, and the developer has confessed he does not have time to fix it right now. The easiest way to test this is to borrow either a battery or power adapter to test in your machine. The alternative is replacing the logic board, which is not cost effective on a machine that old, unless gfx does not resolve the issue and you really want to keep this MBP.

This may allow your MBP to run normally, although it will have reduced graphics performance when performing demanding graphics tasks. It will allow your MBP to run on integrated graphics only, bypassing the discrete GPU which has the issues. Install gfxCardStatus ( ) and set it to 'i' (integrated graphics only). So many of this model have the issue that Apple created a repair program for them, but it expired or four years from the original date of purchase. Your MacBook Pro likely has a faulty discrete GPU.
