Powerbook screen turns bluish after sleep

    I have a little problem with my last generation 12" Powerbook G4. Sometimes, after I wake it up from sleep mode, the screen has a kind of blue tinge to it, as if there was some blue transparent plastic stuck to it. After I reboot, it's just fine. What's the cause of this? Thanks!

    Usually a colour tinge such as this can be traced back to a loose GPU connection, but the fact you can remedy it with a restart is bizarre. If you're quite good with opening up computers, maybe get a screwdriver and see whether the connection is firmly in place. iFixit Guides may come in handy if you wanna take it apart. :)
