The unnamed usb device is the fingerprint reader, which I am not using
and do not have a driver for. Soft-blocking wifi and/or bluetooth does
not reduce the 8.11W used by thinkpad_acpi, and anyway, i'm somewhat
suspicious of that assignment of power consumption.

Title:
CPU runs at high speed after upgrade
Status in linux package in Ubuntu:
Confirmed
Bug description:
After a dist-upgrade from 15.04 to 15.10, moving from kernel 3.19.0-43
to 4.2.0-23, my laptop CPU runs continuously at 3GHz, and never slows
down to 800MHz, as it used to. This has reduced my battery life from
24 hours to 8 hours.
