Water damage, Strange GPU issue
I had a Macbook Pro without a backlight issue and I asked for help here
Now I managed to solder another LCD connector and the backlight is back. The problem is now I'm having a strange GPU issue.
Whenever there is a change between the discreet GPU and the integrated GPU my Macbook freezes and won't work unless I reboot it. For example, I turn it on and everything works until I open for example, iPhoto or Spotify or Chrome. The other way around also happens, if I turn the macbook on with an external monitor plugged they'll work fine until I unplug the external monitor. In that moment the macbook will freeze.
Has anyone experienced this issue? It's clearly something to do with the switching mechanism!.
Ist dies eine gute Frage?
