I have this weird problem with Lubuntu 12.04, which has seemed to get only worse with the upgrade. Strangely, whenever my laptop is charging, it causes a massive slow down. It does not really matter what the temperature is at the point of charge, but it always slows down. When I unplug it, it resumes normal speed. Is anyone else having this problem?
