I have an IBM T41 that runs current snapshot. I put it in suspend mode

Is there any way to avoid this other than turning off the the system

Thanks.
Check out the difference between suspend & hibernate; suspend uses battery
power to maintain memory state for a quicker restore, hibernate flushes
memory to disk and uses no battery power.
Is there any way to hibernate the box instead of suspending it with
"apm -z" or "zzz"?
You have to create a "hibernation" fdisk partition on your disk and use
tphdisk utility from ports to create a hibernation file there. Whole
procedure is described in the built-in help in the utility.
When you are finished, just press Fn-F12. Whether there is any way to
start hibernation from software is still an unresolved question to me.
Also, bear in mind that hibernation writes all your RAM contents to disk
unencrypted, making swap and any disk encryption pointless.
