Package: acpi-support
Version: 0.109-5
Severity: normal

Dear maintainer,

The apm level of my harddrive is set to 254, as
 hdparm -I /dev/sda
reports.
After a resume from suspend (using the KLaptop utility) the apm level is 128 
(the default setting).
If I then try
$ /etc/init.d/acpi-support restart
this does not work.

When I issue
 /etc/init.d/acpi-support stop
and
 /etc/init.d/acpi-support start
the apm value as read from
 hdparm -I /dev/sda
is back at 254

I thought to report this since values of 128 and below cause clicking sound
form the unloading of the HDD heads on the ramp.
I think KLaptop uses acpi-support, but I'm not entirely sure how to check this,
so I filed the bug here.

Secondly, I want to ask why apm level is still set to 128 when on battery?
Is this to safeguard the disk from sudden movements?
In my case (probably quite irrelevant to report this individual case, but still)
the HDD is a Hitachi Travelstar 7K200 and the white paper reports the following:
apm 192-254: active idle mode, 50% less power
apm 128-191: low power idle mode, 60% less power, unload heads
apm 1-127: standby 
apm 0 or 255: aborted (?)
so for power saving when on battery, 128 is not needed.

kind regards,
take care,

Steven
