It definitely appears as though the "Spin down hard disks when possible" on the "On Battery Power" tab of the power management applet is not being respected. I have the option unchecked, and can observe the following:
dan...@thinkpad:~$ sudo hdparm -B /dev/sda /dev/sda: APM_level = 254 (remove AC) dan...@thinkpad:~$ sudo hdparm -B /dev/sda /dev/sda: APM_level = 1 If I manually "sudo hdparm -B 254 /dev/sda" after going to battery mode, then the hard disk obviously stops the incessant and overly ambitious spinning down. I'm all for spinning down disks when on battery power, but if I specifically uncheck that option in the power management applet, it should be honoured. Also, when spinning down disks, something a bit more sensible like a 2 or 5 minute idle period would be better (can we have this adjustable maybe?) -- [maverick] HD spins down all the time on AC https://bugs.launchpad.net/bugs/606706 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
