Hm, I don't have a laptop and the help text for this kernel option says: : Generally, if you don't have a battery in your machine, there isn't much : point in using this driver. So, I guess turning this option on doesn't help me much, right?

Unfortunately, you were right: 'hdparm' can't handle SCSI disks. > You might install "hwutils" and try that. I haven't found this yet, but will check it out. Is Linux using the BIOS APM settings (CPU frequency lowering etc.) at all? Thanks a lot for your hints!
