--- Comment #58 from Jean Delvare
I was using laptop-mode-tools for some time after I bought my notebook. After upgrading to openSUSE 12.3 I recognized, that laptop-mode-tools gave me no more power saving (on openSUSE 12.2 it still used a lot). So I uninstalled laptop-mode-tools and after that, the hdd-clicking issue began. So on notebook with laptop-mode-tools this bug may not appear, as long as laptop-mode-tools are running.
Indeed, if you look at /etc/laptop-mode/laptop-mode.conf, you'll see: CONTROL_HD_POWERMGMT=1 BATT_HD_POWERMGMT=128 LM_AC_HD_POWERMGMT=254 NOLM_AC_HD_POWERMGMT=254 I _do_ have laptop-mode-tools installed on my laptop and it's on AC most of the time, which explains why I had -B value 254. It gets down to 128 when I switch to battery, and back to 254 when I plug the AC adapter back in. This also explains why /proc/acpi/battery/BAT0/state did not reveal a significant difference: -B value was 128 all along. Doing the proper comparison now, the difference is about 420 mW. Thanks for the tip about powertop only showing power consumption when on battery - same here, of course. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
