Hi
I have found a problem with my laptop thanks to powertop, but I dont find
how to fix it anywhere. I noticed my batery life was much shorter in Kubuntu
(2 hours) than in windows 7 (3.5h) and while trying to change that i
installed powertop. My results are:
most of the time im working on C3 state (which is the best supported by my
CPU and BIOS) but residency time is very short, about 5ms. Wapeups per
second occurs aproximatelly 400 per second.
Powertop doesn't show me the list of applycations causing wakeups, but do
tell me about certain problems (one different but similar message everytime
it refresh). They all are about:
- program <<'Xorg>> is writting file ... on /dev/sda7 and this prevents the
disk to go on safe energy state
<<'firefox-bin>> on /dev/sda7
<<'plasma-desktop>> "
...
(others on /dev/sda5/
I think fixing that will get my disk into safe energy state normally and get
longer sleeping times
But I don't find what could I do to fix that.
Could you provide me some help?
Thanks a lot
Javier
