Sometimes coincidence can be frightening : yesterday, I noticed that my computer screen refused to deactivate DPMS. Rebooting the computer revealed that the screen had died on me. At the same time, my laptop battery went dead. Plugging in the power cord didn't resume the laptop, and even after rebooting, the laptops screen remained black... WTF ? Only after a second reboot, the laptop showed a screen again. Spooky, isn't it ? Luckily I still had an old screen lying around, but working at 800x600 isn't much fun.
