Hello,
I'm runnning NetBSD-10.0/amd64 on an old Toshiba Satelite laptop
and am having trouble obtaining the current battery charge under
the following conditions:
- system is booted with AC disconnected (battery only)
For the above condition the "last full cap" in envstat(8) output
reads "N/A" and the "charge" is grossly low:
--
$ envstat -d acpibat0
Current CritMax WarnMax WarnMin CritMin Unit
present: TRUE
design voltage: N/A
voltage: 15.000 V
design cap: N/A
last full cap: N/A
charge: 4.000 Wh
charge rate: N/A
discharge rate: 22.582 W
charging: FALSE
charge state: NORMAL
--
After the AC is connected -- momentarilly -- the envstat(8) output
is correct and I can divide "charge" by "last full cap" to get the
current charge:
--
$ envstat -d acpibat0
present: TRUE
design voltage: 10.800 V
voltage: 10.800 V
design cap: 47.520 Wh
last full cap: 26.373 Wh
charge: 26.110 Wh (99.00%)
charge rate: 6.058 W
discharge rate: N/A
charging: TRUE
charge state: NORMAL
--
Here's is the battery-related info from dmesg(8) _before_ toggling
the AC adapter:
--
$ dmesg | grep bat
[ 1.029262] acpibat0 at acpi0 (BAT0, PNP0C0A-1): ACPI Battery
[ 1.950617] acpibat0: autoconfiguration error: failed to evaluate _STA:
AE_NO_MEMORY
--
Unfortunately I don't know how to interpret this autoconfig error.
Once AC adapter is toggled I see this:
..
[ 32.489257] acpibat0: normal capacity on 'charge state'
I also noticed that there is no "bat0" entries for 'sysctl hw.acpi.'
though I don't know if there ought to be.
I'm wondering if there's anything I might try to correct this issue
and/or possible work-arounds if not actualyl fixable?
Thanks,
B
