Hi all,

Tested a couple of Getac laptops recently with latest amd64 snapshots.
Both have dual batteries attached to acpibat(4) and both show 0
remaining battery capacity.
Apart from that most other battery properties are OK and sysctl reports:
hw.sensors.acpibat0.volt0=11.10 VDC (voltage)
hw.sensors.acpibat0.volt1=11.63 VDC (current voltage)
hw.sensors.acpibat0.current0=0.39 A (rate)
hw.sensors.acpibat0.amphour0=2.01 Ah (last full capacity)
hw.sensors.acpibat0.amphour1=0.00 Ah (warning capacity)
hw.sensors.acpibat0.amphour2=0.00 Ah (low capacity)
hw.sensors.acpibat0.amphour3=0.00 Ah (remaining capacity), OK
hw.sensors.acpibat0.amphour4=2.10 Ah (design capacity)
hw.sensors.acpibat0.raw0=1 (battery discharging), OK
hw.sensors.acpibat1.volt0=11.10 VDC (voltage)
hw.sensors.acpibat1.volt1=11.63 VDC (current voltage)
hw.sensors.acpibat1.current0=0.40 A (rate)
hw.sensors.acpibat1.amphour0=2.04 Ah (last full capacity)
hw.sensors.acpibat1.amphour1=0.00 Ah (warning capacity)
hw.sensors.acpibat1.amphour2=0.00 Ah (low capacity)
hw.sensors.acpibat1.amphour3=0.00 Ah (remaining capacity), OK
hw.sensors.acpibat1.amphour4=2.10 Ah (design capacity)
hw.sensors.acpibat1.raw0=1 (battery discharging), OK

Inserted a couple of printf lines in sys/dev/acpi/acpibat.c to see
what could be happening. The battery state for capacity in
acpibat_getbst, line sc->sc_bst.bst_capacity =
aml_val2int(res.v_package[2]); always reports a value of "1". The
other 3 bst properties for voltage, rate and state are correct.

Perhaps the AML parsing is breaking on some unexpected DSDT _BST
values. If anyone is interested, I've uploaded the gzipped DSDT.dsl
to:
https://limewire.com/d/10e22f54-79da-456b-b492-c67e5cd40f81#EQDxKXdMDt05voTVeono-cfx3tgF3MJP9RdUhiEPEKg

Perhaps someone has already seen this issue before, I would appreciate
any help or pointers.

As a side note, also tested with FreeBSD live usb boot and the
remaining capacity showed up OK (same in Linux).
