[Bug 563156] Re: [ATI Graphics][Lucid] laptop runs hot, shorter battery life, fan always on

[Michael B]

Same problems here, I'm using a HP 6540b with a mobility RADEON 4500.
With the opensource-driver the fan was always running,  /proc/acpi/thermal_zone/ shows over 70 degrees, battery is emptying very shortly, xfce-powermanager is unable to change display brightness using [FN + F9/F10].

After installing the propr. ATI driver (fglrx), temprature is reducing
to about 55 degrees, fan is running very slow, battery is running much
longer, and xfce-powermanager is able to change the display brightness.
