I must admit that I've never had this problem myself. (And I think
your problem is that apmd reacts too fast, and shuts the system down
while it is in the middle of a sync.) In any case, it is easy to

For the terminal screen, you can set these parameters with `setterm'
(-powersave and -blank options). For X, you may want to include
`Option "power_saver"' in the XF86Config file, and then specify the
BlankTime, StandbyTime, SuspendTime, and Offtime parameters. When
power_saver is enables, you can `xset -dpms ...' to fine-tune these.
For hard-disks, you set the spindown by using hdparm as well.
However, if you use hdparm then that setting won't be retained over a
resume. (I patched apmd to call the requisite script after every
resume, that way I get a spindown in any of the power modes.)
Note that in order to actually get a spindown, you'll have to increase
the time interval of `update' to something like half an hour (in
/etc/init.d/boot). Moreover, you may want to edit /etc/syslog.conf to
discard most of the output from various daemons.

Yes. Two of these are fixed, the third you can configure to your own
liking. For that option, I picked low brightness (the greatest
powersaver AFAICT) with fast CPU but the "silent" cooling method.
This gets me responsiveness with a reasonable battery life for my
