Установил на ноут HP pavilion dv 5-1164er Debian Sqeeze. В Linux батареи хватает максимум на 2 часа.

Что это за хрень /usr/bin/x-term : hrtimer_start_range_ns (hrtimer_wakeup) и <kernel core> : hrtimer_start_range_ns (tick_sched_timer] и как с этим боротся. 68,9% (340,4) [ ] <interrupt> : PS/2 keyboard/mouse/touchpad
а с этим как бороься.
Версия ядра:

2.6.32-5-686.Поможет ли пересборка ядра.
