So I was using my laptop (drawing in Krita with a Wacom tablet on Debian Wheezy) and the screen suddenly turned blue (like a Windows crash dump) and now looks like the attached image:

enter image description here

Does anyone understand what is going on? The screen is now frozen like this. What's worse, the power button isn't working now, so I can't restart. What can I do now, besides wait for the battery to die?

    you might remove your battery to reboot the machine. Also, almost every laptop would physically turn itself off if you'll hold your powerbutton for ~5 secs. After that, you want to get logs from /var/log (I'm not exactly sure what do you want to get from there on wheezy) and post them, since this image is inconclusive. – Mikhail Krutov Apr 13 '16 at 05:47
  • Alright, I don't have screwdrivers at the moment so I guess if the battery doesn't run out by morning I will take it out. And yes, I've been holding the power button down for a long time, nothing happens. Can any hints at all be gleaned from the image? I'm afraid I don't understand what's going on there. Also will check logs if booting up again works. That's what I'm worried about... – Ted Desmond Apr 13 '16 at 05:49
  • Update: Power ran out in the morning, so I plugged the charger in. After a few seconds, I turned the power on and the usual lights displaying that the computer is on and charging lit up, but the screen was completely dark, which worried me quite a bit. Later in the day I retried that and the computer booted up (good thing, I thought my CPU fried or something). I'm looking through /var/log/, but there is a lot in there... – Ted Desmond Apr 13 '16 at 16:05
  • http://unix.stackexchange.com/questions/38608/how-to-determine-why-my-computer-crashed <- this link might help. However, this might be outdated since Debian got `upgraded` to systemd. – Mikhail Krutov Apr 13 '16 at 19:21
  • one more thought - what I'd do was to `grep -R ` 110381 timestamp through /var/logs. It would yield the file you need (chances are that it would be not only that file, but you'll be able to deduct what exact log file do you need). – Mikhail Krutov Apr 13 '16 at 19:23
