Michele, Can you post the output of the following command ? grep POWERMGMT /etc/laptop-mode/laptop-mode.conf
Is your kernel error message resolved ? BTW, here's what hdparam says -B Set Advanced Power Management feature, if the drive supports it. A low value means aggressive power management and a high value means better performance. Possible settings range from values 1 through 127 (which permit spin-down), and values 128 through 254 (which do not permit spin- down). The highest degree of power management is attained with a setting of 1, and the highest I/O performance with a setting of 254. A value of 255 tells hdparm to disable Advanced Power Management altogether on the drive (not all drives support disabling it, but most do). By default, LMT, when ON_BATTERY, will set it to 1. If you don't like the power saving behavior for your hard drive, you can disable it in /etc/laptop-mode/laptop-mode.conf -- Harddisk stops working after wakeup https://bugs.launchpad.net/bugs/358943 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
