Package: laptop-mode-tools
Version: 1.41-1
Severity: normal
--- Please enter the report below this line. ---
When switching from battery to AC two command are executed
in /usr/share/laptop-mode-tools/modules/wireless-ipw-power, which are for my
ipw2100 card:
/sbin/iwconfig eth1 power off
/sbin/iwpriv eth1 set_power 5
According to man iwconfig the first command disabled power management, so that
the second has no effect. This results on a significant higher temperature in
my laptop (Thinkpad X40) of:
CPU=41 GPU=42 MB=46 MiniPCI=39 BAT=35 N/A=-128 BAT=33 N/A=-128
with power management off than having it on:
CPU=41 GPU=42 MB=46 MiniPCI=37 BAT=35 N/A=-128 BAT=33 N/A=-128
(consistent temperatures in a few runs, temperatures after 10~15 min idle, fan
off)
So it should be changed to keep powermanagement switched on, and to use the
power level for AC instead of the battery one (just a typo).
Thanks,
Sten
