I've been reading through these posts and I can't tell if there is something I should fix. I understand the kernel is taking the setting from the bios, but I can't understand if there's something I should fix beyond that. My Dell Latitude laptop has a Hitachi HTS54161 hard drive. It says this: # /sbin/hdparm -I /dev/sda | grep "Advanced power management" Advanced power management level: 128 (0x80) Is there something I'm supposed to fix or not? -- Paul E.
