[Bug 555315] Re: ondemand CPU Scaling does not work when AC adapter is plugged in
Additional information: When I set the governor to performance, then when the laptop is on battery power the CPU frequency is ramped up from 1.60GHz to the full 2.80GHz. When the A/C power adapter is plugged in and the governor is set to performance, the CPU frequency remains at 1.60GHz and never increases. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-applets in Ubuntu. https://bugs.launchpad.net/bugs/555315 Title: ondemand CPU Scaling does not work when AC adapter is plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-applets/+bug/555315/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

When the AC adapter is plugged in, this range is bounded to 800-800.

This bug also affects me. When on battery, cpu frequency scales properly on-demand 1.6 to 2.8 GHz.
