The situation is as follows: When I shutdown the laptop from either SL 6.3 or Opensuse 12.2, the battery keeps draining (badly in SL6.3 ,eg 30% in 12hours) or very slowly (10% per day when shutting down from OpenSuse). Shutting down after using Windows, does not result in such a loss. I found a couple of similar reports on the net: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/110784, http://ubuntuforums.org/archive/index.php/t-2052582.html and http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=64779 The last one is especially relevant as it shows that the laptop can keep some components "live" even after shutting down. Unfortunately, as far as I can tell, I have disabled all these options in my BIOS but still experience the drain. In SL6.3 ignores my BIOS setting and I had to explicitly turn off the wake-on-lan option using "ethtool -s eth0 wol d" but OpenSuse reports it as disabled. Yet there still appears to some other component that does not get switched off completely. The work-around is to not shutdown but reboot the laptop and then hit the power button at the grub menu. That way the laptop is shutdown safely and switched off completely. However, that is a rather cumbersome solution and I'd be keen to find a better one! I have attached the output of both lsusb -vv and lspci -vv. Note that the lsusb file contains an entry at the very end that says that the Atheros bluetooth adapter has remote wakeup enabled which might be the culprit? Reproducible: Always Steps to Reproduce: 1.boot into Opensuse 2.shutdown Opensuse Actual Results: laptop battery drains more than it should Expected Results: battery drain should be similar to the one achieved after shutting down from within Windows -- 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.
