Bug Description
Binary package hint: pm-utils
IMHO, the power saving defaults in /usr/lib/
Also, this should be documented (not only what it does, but why those values were chosen) and user changeable. If the default is so aggressive, it also should be adjustable user-friendly, i.e. graphically.
Defaults as per pm-utils 1.4.1-1:
* hdparm -S (spin down): AC 0 (disable), battery 6 (should correspond to 6*5 = 30 seconds, but see above)
* hdparm -W (drive write cache): AC 1 (enable), battery 0 (disable). Why would we need to disable write caching on battery -- just for the case that it runs out of energy?
* hdparm -B (advanced power management): AC 254 (minimum saving), battery 1 (maximum saving). Too aggressive IMHO, causes my HD, provided spin down (-S) is disabled, to frequently unload the heads (SMART load cycle count is skyrocketing).
* hdparm -M (acoustic management): AC 254 (maximum performance), battery 128 ("max quietness" as commented on in [...]/power.
I'd please like to hear the opinions of the maintainers.
Regards,
Björn

This affects me too. After just about every Ubuntu upgrade, I need a different fix for this. This time around I found http:// ubuntuforums. org/showthread. php?t=1605416 (just venting some frustration).
