Comment 33 for bug 463940

My HP Envy 15 information can be found at http://qabe.net/envy15/. My BIOS version is F.05 dated 2009/10/06. My computer arrived on 2009/11/02.

My BIOS seems to have working CPU fans. They start off slow, speed up with CPU load and temperature, and return to slow speed when temperature returns. I spent at least 16-minutes at full load (compiling Ubuntu's kernel) without trouble, and everything returned to normal when finished.

P-states appear to be working fine, but C-states are not functioning properly, which means that power consumption at idle is still higher than it should be, and "turbo" does not work since no core is ever asleep.
