Ubuntu hanging at shutdown
After having installed laptop-mode-tools on my laptop (HP Pavilion dv3) with Ubuntu 12.04, when I try to shut it down, it hangs with a black screen, the ubuntu logo and the power light on. I need to hold the power button in for a few seconds before the machine actually shuts off. This also happens if I choose restart and both of them only when I'm running the laptop with the battery.
If I remove laptop-mode-tools, it works perfectly.
