[Bug 1246793] Re: Battery charging slows down laptop
apport information
** Tags added: apport-collected saucy
** Description changed:
Following up on Bug #962712 which was marked as invalid, instead of
fixed (gee, thanks...) I'm using Ubuntu 13.10 and this still happening
pretty badly.
Steps to reproduce:
1) Unplug laptop, plug-in second monitor, drain battery until OS warns user and asks her to plugin laptop
2) Plugin laptop
Expected: Laptop works normally
Actual: Laptop slows down severely.

Drilling down, run `cpufreq-info`
Expected:
driver: acpi-cpufreq [...]
current policy: frequency should be within 800 MHz and 2.80 GHz.
Actual:
driver: acpi-cpufreq [...]
current policy: frequency should be within 800 MHz and 800 MHz
-=-=-
Drilling down, this is known, lingering problem, and is not "invalid",
please triage instead of sweeping under the rug
