If I close the laptop (goes to sleep mode) and open it too quickly, then the screen will come back almost black. Reboot doesn't help. I'll have too remove all power sources for a couple if minutes and then the computer eventually works again...
Or just closing the laptop and wait for a couple of hours does also seem to help.
So far we've talkt abouta Vista. Another way to induce the error is to try sleep mode from Ubuntu. That will always put the computer in this sad condition. Annoyinig.
Dell first wouldn't help 'cause I have Ubuntu installed too... Eventually they agreed that something is wrong and offered to replace the screen. But I don't think that would help. To me it seems like a bug in some firmware.
What to you think?
