My Hp Pavilion N5445 laptop will not cool normally. It will pass the "Fan Test" just fine (Fan Test in HP diagnostics turns on the fan for a few seconds. If you see or hear it operating, it passes). It is not dirty, although I have not taken it apart to inspect further. I reloaded the software from the included HP Recovery disk set with no improvement.
The chipset is Intel® 82801CAM I/O Controller Hub 3 (ICH3-M). This chipset supports Active Cooling (From the Intel documentation: Active cooling involves fans. The GPIO signals from the ICH3 can be used to turn on/off a fan.)
Is there any way to troubleshoot this or use the Command Line to invoke the operation of the fan?
