Here is the story with update:
My mbp is slow and i run hardwaretest. It shows errorcode: 4vdc/1/40000003: Videocontroller.
(10/5) I take a photo of the screen with the errorcode.
(13/5/) I bring a print of this and my computer to humac (danish applestore) where they take it in for repair. They can't find the error with their software and they get my system CD too. They now see the error and change my motherboard.
(10/6) I get it back but while checking for scratches in the humac store I discover a scratch/hole in the middle of the screen and i give it back to them to get it fixed.
(16/6) I get it back with the note. They don't think that they made the scratch. I discover that there is no scratch on the photo i took (10/5) and take a new one for reference.
The following weeks i confront them with the photos and complaint to: Humac service (they don't care), The boss of humac Denmark. (he doesn't care), The boss of Apple Denmark (he doesn't even answer my mail).
I don't know what to do more, since i have proof. They don't care about the proof.
I run hardwaretest again and the errorcode is back: 4vdc/1/40000003: Videocontroller. (It wasn't there when i got it 16/6)
(18/7) I give my mbp and my system CD back to humac to get it fixed again.
30/7) I get it back. Nothing fixed but with a burned CD with their own Hardwaretest showing no error. Mine still shows the error, but apparently it is a bug on my system CD, that makes the computer think it has a error.
Nice solution humac!
So, now if i have to re sell it, i have to give discount because of the scratch, and explain that "sure the system disk shows an error big enough to change the motherboard, but look at this burned CD. It shows no error."
I guess im pretty much stuck with this machine till it dies. Probably sooner than later.
That's my story, thanks for reading.
