Just curious, where does this message pop up? I tried clicking on the battery icon (lucid 5.2) and it just gives me a tooltip bubble.

Should be located @ /root/Startup/powerapplet_tray

It seems to look for info @ /proc/acpi/battery/BAT0/alarm info state

might be problematic if you boot with acpi=no
or your BIOS dates before 2001 which would mean that acpi is disabled by default ( changeable in the Kernel Configuration at compile time )
which would mean to boot with acpi=force to enable it,
which would disable apm automatically
and might lead to different shutdown behaviour .

There is also the acpi battery driver module
Code:
modprobe battery

Just checked again
Code:
grep 'CONFIG_ACPI_BLACKLIST_YEAR' /etc/modules/DOTconfig-K2.6.30.5-01SEPT09-TICKLESS-SMP

Quote:
CONFIG_ACPI_BLACKLIST_YEAR=2002


and

Quote:
acpi= [HW,ACPI,X86]
Advanced Configuration and Power Interface
Format: { force | off | strict | noirq | rsdt }
force -- enable ACPI if default was off
off -- disable ACPI if default was on
noirq -- do not use ACPI for IRQ routing
strict -- Be less tolerant of platforms that are not
strictly ACPI specification compliant.
rsdt -- prefer RSDT over (default) XSDT
copy_dsdt -- copy DSDT to memory

See also Documentation/power/pm.txt, pci=noacpi


I am still testing kernel params to enable the it87 temperature module against acpi with support for real poweroff[ not standby ].
So excuse for '2001' and 'acpi=no'

It would be interesting to hear , if your're able to load the "apm" module
