For laptops, that is. Or at least, for ThinkPads.
It turns out that my video problem was the computer getting confused. As I was in a hurry leaving the Solution Centre, I just put my computer in standby while it was still connected to an external monitor. Afterwards, each time I tried using it only with its own display, I would get these multi-coloured bars on the display, making it unusable – even after a complete shutdown. So when I got back home, I took it to our IT folks to get it repaired. They booted it up, saw the problem, rebooted and wrote up a ticket about it. Then one of them decided to hook it up to an external monitor just in case… Well, it had the same symptoms when booted up, until he logged in to Windows. At that point everything worked!
Our only guess is that the video card got set to a strange mode and could not be reset until an external monitor was connected. Interesting feature!
Can I get a Mac?
