I have an HP notebook. For me the problem arises precisely when on battery. When on AC the system scales correctly, both with battery in or off its location; just pull off the AC charger and the max frequency locks down to 800MHz per preocessor, which actually is the minimum possible. So the issue is probably related to power management. A fast heuristic test: time 'google-chrome' - on AC: 0.559s; just pull of the AC charger: 1.495s
I'm with kernel 3.8.0-19-generic. I've tried with two different batteries, no luck with both. @Atanas: the issue is solved for you both with AC and on battery? Or without AC charger connected do you still experience the problem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174169 Title: Minimum and maximum cpu frequency are equal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1174169/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
