Re: [ACPI-sppt] battery life perl script

I'm running 2.4.21-pre2 on my Sharp MV12W with the acpi support that is 
in that mainline kernel.  I've got some odd contents under 
/proc/acpi/battery:
# ls -l
total 0
dr-xr-xr-x    2 root     root            0 Jul  4 22:23 0
dr-xr-xr-x    2 root     root            0 Jul  4 22:23 0

Inside of one of them, there's a info and status file, and both have:
Present:                 no

Any ideas what might be going on here?
