    Battery Life Powertop Report over 30W on laptop, please help

    Hi,
    I'm new to ubuntu and I just installed 9.10, I always thought that my laptop had very bad battery support. On vista I could only use it fo100,0% Dispositivo USB 1-8 : USB2.0-CRW (Generic)r a periode of 1:30h more or less.

    Now when I installed PowerTop i found that it reports that my latpot is using about 30W what seems to be a vert high value for it, so its not battery problem, is consumition problem, no?

    Here I paste my proccessor info:
    Code:

    Re: Battery Life Powertop Report over 30W on laptop, please help

    You need to post your laptop's specs, without them we can only guess if that figure is reasonable or not - some laptops are designed to be very energy efficient, but there are also "desktop replacement" monsters with huge screens, multiple hard disks and powerful video cards that aren't really meant to be used unplugged.

    Re: Battery Life Powertop Report over 30W on laptop, please help

    Vedo che sei italiano, al max mandami un msg privato, cmq ti rispondo in inglese x correttezza.

    run
    Code:
    gedit usb_autosuspend.sh
    and paste this
    Code:
    for i in /sys/bus/usb/devices/*/power/level; do
    	[ "$(cat $i)" = "auto" ] && continue
    	echo "auto" > $i
    done
    
    for i in /sys/bus/usb/devices/*/power/autosuspend; do
    	[ "$(cat $i)" -ge 0 2>/dev/null ] && continue
    	echo "2" > $i
    done
    Close and save the file.

    Now run
    Code:
    sudo ./usb_autosuspend.sh
    and then re-run powertop

    comes back when you have the results

    Re: Battery Life Powertop Report over 30W on laptop, please help

    Googling around I found a few complaints that this model is power hungry even when running Windows, which seems to be consistent with your own observations.

    Considering that most manufacturers use Windows as the target platform and provide drivers optimized for it, that's a pretty bad sign overall... not sure if/how Linux can do better here.

    The only thing I noticed which may have some potential is your GPU - it may support some power saving features (lowering clock speed when on battery power etc.) that often aren't enabled by default. It looks like you're using the radeon driver, see if you can get the "DynamicClocks" feature working (may have been renamed to ClockGating/DynamicPM? Not sure, maybe someone else with similar hardware can help you with this...).

    your usb port doesn't go in autosuspend and that prevents the cpu to go idle. I have no idea why autosuspend in linux is so complicated but that's how it is.

    I advice you to re-run that script that I made you wrote, on and off ac and then
    Code:
    sudo su
    cat /sys/bus/usb/devices/*/power/level
    and
    Code:
    cat /sys/bus/usb/devices/*/power/autosuspend
    exit
    all levels should say auto and all autosuspend should say a number above 0, in a normal case where usb get autosuspended.

    Let us know.
