Please. It is the first time I heard of this event... Here are some questions, to help track it down: 1. Did you ever get that event while the Quadro was *disabled* in BIOS? 2. Do you get that event when you switch to BATTERY only? Or do you get it also when you switch back to AC ? Maybe you could test it in single user text mode, as that might help avoid the crash... Thanks in advance for any help you can give so that we can track down what that event means... -- "One disk to rule them all, One disk to find them.
