Every time I reboot or shutdown my laptop, while the laptop is booting again I get a screen (before loading the OS) that HP discovered overheating and system went into hibernation. But the point is that the laptop is not overheating nor going into hibernation by itself.

Also, because of the hybrid graphics card I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use Unity 3D. Also, OpenGL doesn't work as it should (with Cairo Dock).

As I've read some posts, people say that vgaswitcheroo doesn't work on 12.04 so I haven't tried it.
