Play this video at maximum volume in full screen or

browsing the Web via WiFi.


Under Windows 7 lasts ~5 hours.

Under Kubuntu 10.10 only ~2 hours.


I have the Acer Aspire 1810TZ. The deterioration of the battery 90%.


Installed:

acpid

acpi-support

pm-utils

upower


Not ustanovleny:

laptop-mode-tools


I love Linux, not going to change.


What to do to make it work at least?
