- Basically this is not an isolated case since its happening to a lot of users,
- the culprit of this problem appoints to be "flash last update"
- currently the only solution is to turn off the "automatic graphic switching" which mean less battery power on MBP's.
- Replacing Logic Boards or any other piece of hardware will NOT fix this problem, so it's worthless if the Apple technician replace any piece.
The only real solution we need is Apple to launch a firmware or update to fix this.
