I've just installed Ubuntu 11.10 64-bit on my laptop
HP Pavilion g6-1058er and I've got problems with it.
When I shut down or reboot my pc, when I turn it on again, my bios gives me this warning:
(something like this)
Your PC was shut down or rebooted because of overheating...
and also this problem was when I had Ubuntu 10.04 installed, when I'm working on Windows everything is ok.
