HP Compaq nc4010 BIOS Battery Information

[Infiltrator]

I have an HP Compaq nc4010 laptop, with Debian experimental installed on it.

In the BIOS utility, I can view what they refer to as "battery information".
Unfortunately, it's all horribly abbreviated, so I can only guess what the labels mean.

Is there any way I can acces this same information from linux, preferably with full labels and/or descriptions?


I shall also add a sample of the information in case anybody is familiar with it.

C1  3600
C2  -54
C3  0
ME  2
CC  235
T   26
TV  9894
C   -2141
DV  11100
MN  SIMPLO (or maybe zero, not too sure)
CV1 0
CV2 3261
CV3 3323
CV4 3305
S   BDO

Battery info in primarily in /proc/acpi/battery

You can get a lot of info by doing

cat /proc/acpi/battery/BAT0/info
cat /proc/acpi/battery/BAT0/state

Note that the battery name may be different, or if you have more than one battery, there could be multiple entries, such as BAT1, BAT2, etc.

Also, you might be interested in the program powertop.

Thanks for your reply, reed9, but I do not have a battery folder in /proc/acpi. And yes, I'm checking it as root.

# ls /proc/acpi
button  embedded_controller  fan    power_resource  sleep   video
dsdt    fadt                 info   thermal_zone    wakeup

Hmm.

Try looking is /sys/class/power_supply/BAT* instead.
