You have to suspend the machine using APM, instead of shutting it down.
I'd suggest using standby mode.

a la APM man page:

APM(1)              Linux Programmer's Manual              APM(1)

NAME
        apm - query Advanced Power Management (APM) BIOS

SYNOPSIS
        apm [ -vVmsS ]

DESCRIPTION
        apm  reads  /proc/apm  and presents the output in a human-
        readable format.  Since primarily battery status  informa­
        tion  is  provided, this command is most useful on laptops
**-->  with a compliant APM BIOS.  apm also allows the machine to
**-->  be put into standby or suspend mode.

OPTIONS
[snip]
        -s, --suspend
               Put the machine into suspend mode if possible.

        -S, --standby
               Put the machine into standby mode if possible.



ergo: apm -S
