I've been regularly using: echo low | sudo tee /sys/class/drm/card0/device/power_profile
I've am also using psensor to warn me if the temperature rises above 92°. When 'idle' the temperature is at about 80°. If the CPU is used (merely starting eclipse and letting all the the startup validation processes finish) it quickly rises to 88°. If the usages is sustained (rebuilding a java project) the temperature oscillates between 95° and 98°. If I do anything else that adds to the load (ie. if the temperature is >98° for short period of time), the system freezes, but the everything remains on, fans and CPU temperature stays up. I need to turn off the notebook by keeping the power button pressed. Note that this system overheats /with/ the low power profile. Here are some general stats about this system, please let me know, if I can provide further information: HP Presario CQ61 320eg AMD Turion(tm) II Dual-Core Mobile M500 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV710 [Mobility Radeon HD 4300 Series] (prog-if 00 [VGA controller]) Linux schiefer 3.2.0-33-generic #52-Ubuntu SMP Thu Oct 18 16:29:15 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ayers@schiefer:~$ lsmod|grep rad radeon 804503 2 ttm 76949 1 radeon drm_kms_helper 46978 1 radeon drm 241921 4 radeon,ttm,drm_kms_helper i2c_algo_bit 13423 1 radeon This started after the upgrading from Maverick.
