Public bug reported: Thread link: https://answers.launchpad.net/ubuntu/+source/acpi/+question/143039 I installed the applet as I suspected my CPU was at half speed. When I first start the computer it works correctly and then for no apparent reason the governor switches the max speed down to 800MHz and it will not increase it later. The fan doesn't come on so I do not think it is because the CPU is hot. I have attached the info below. Every day after about 15min of starting the computer up the governor will change the text from: current policy: frequency should be within 800 MHz and 1.73 GHz. current policy: frequency should be within 800 MHz and 800 MHz.
It then remains at 800Mhz for the rest of the time the computer is on.
