I also have the problem with my laptop fan which is almost always on when the power cable is attached.
Apparently my state is T8 even though the largest state available is T7: $ cat /proc/acpi/processor/CPU0/throttling state count: 8 active state: T8 state available: T0 to T7 states: T0: 100% T1: 88% T2: 75% T3: 63% T4: 50% T5: 38% T6: 25% T7: 13% ** Also affects: linux-source-2.6.24 (Ubuntu) Importance: Undecided Status: New -- laptop fan on full speed all the time https://bugs.launchpad.net/bugs/157388 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
