Bug Description


I recently got a Dell Latitude E5520 with Ubuntu 11.10 All is fine with it excepted when the battery is low and the power supply is plugged: the machine comes really really slow and is no more usable until the battery state is about 75%. It seems kworker/X processes are launched and consume the cpu when plugged.

Any help would be really usefull for me,

Best regards,
