>Description:
I own an "Acer Travelmate 4100" laptop that by default comes with non-working battery status. I fixed the ASL a couple of months ago and realized when upgrading my system to 6.1-RELEASE the other day that the problem still exists - using the latest BIOS from the vendor. Below you will find a diff, old and new ASL as well as dmesg.

After changes have been made in /boot/loader.conf 

acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/DSDT.aml"

battery status is shown as:

AC Line status: off-line
Battery Status: low
Remaining battery life: 15%
Remaining battery time:  0:21:00
Number of batteries: 2
Battery 0:
        Battery Status: low
        Remaining battery life: 15%
        Remaining battery time:  0:21:00
Battery 1:
not present
Resume timer: unknown
Resume on ring indicator: disabled

Maybe this can be used to fix the ACPI problems for the Acer Travelmate series.
