Macbook Pro screen goes blank when disconnecting Magsafe adapter
The only way I can restore the display is to restart the machine. Has this happened to anyone else? Only major change was the install of 10.5.6 update a couple of weeks ago. I have had the dreaded NVidia distorted video problem about 6 months ago, but that's not happened since. Machine temperature doesn't seem excessive--CPU is at about 130 F when charging.
Thanks in advance
