["my8192" <my8192@xxxxxxxxx>]

I have a UL30-A2 running Karmic.

Has anyone else noticed that the HD clicks when on battery, and the 
Load_Cycle_Count (using smartctl) increases around 4 times a minute, or more.

I tried setting "hdparm -B 192", and this stops the clicking and 
the increasing Load_Cycle_Count.

It seems that when on battery the HD (Seagate ST9320325AS) automatically
sets its APM mode to 128, which causes the HD's heads to park/unpark.

On a separate topic, I've enabled laptop-mode, and have reduced my battery 
power usage from around 10.1W to 7.6W (based on values from powertop). 
I now have over over 10 hours of real notebook use when on batteries.
