This question has also been posted in the apple forum, but nobody gave any response.
Hello!
I have a very strange issue with my macbook pro. I recently bought a second hand MBP (model no. macbookpro 5,3). With the integrated 9400 graphics, everything is fine. When I switch to the 9600GT card, logout and login, I notice a strange problem. With the power adaptor connected, everything is fine. As soon as I disconnect the adaptor and put the computer on battery, within 2 sec, the screen becomes grey and locks up. I have waited several minutes and nothing happened. Connecting the power adaptor does not correct the problem and the only option is to hard reset. 9600 GT has 512MB memory. Both graphics cards work very well in games when connected to power adaptor.
Is this graphics card (9600 GT) not compatible to be run under battery mode? Has anyone else encountered this problem?
I have to decide whether to return the laptop as defective or keep it within 7 days. So any input will be welcome.
Many thanks.
