I edited /etc/laptop-mode/laptop-mode.conf and changed this line [1] : BATT_HD_POWERMGMT=1 to this: BATT_HD_POWERMGMT=254 Now I'm not seeing the freezing behavior while running on battery. Well, not as much...maybe once per half hour, which is a lot better that the once or twice a minute I was seeing before at its worst. Will have to wait and see if it's really a result of this change, or just a random fluctuation in an as-yet unexplained behavior. At some point I'll change the BATT_HD_POWERMGMT value back to 1 and see if the freezing behavior returns. For now I'm enjoying being able to actually type in a fluid manner while away from AC power. I suppose battery life will take a hit...guess the tradeoff here is a stuttering user-interface vs. battery life. Sooner or later I'll have to swap the hard disk with an SSD, hopefully that'll lay the issue to rest. But I'm left wondering, am I the only one experiencing this behavior, or is it a known problem that nobody has a solution to? [1] As per laptop-mode.conf(8), this specifies the power management level for the hard drive, values for this option corresponding to those of `hdparm -B` ... hdparm(8) says: 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 Regards, John -- John Magolske http://B79.net/contact -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
