Bug Description
When I installed Utopic it changed the default driver to intel pstate. Ever since then my cpu speed has been locked to 800MHz while on AC power. My cpu is rated for 1.8GHz. Manually setting scaling_max_freq only has an effect when my laptop is unplugged.

His reason for closing it makes no sense. He (and I) had higher clock speeds OFF of AC power, so power limitations cannot be the explanation.
