battery script stopped showing proper percentage

[stef204]

the battery script in the "scripts" repo which I have used for ages has stopped working properly and behaves as such: as soon as X starts and i3-wm launches, I can see proper number for battery. Once it refreshes, it gets stuck on battery 0% red color.

The 0% is incorrect. This has just started to happen recently.

% acpi -b  
Battery 0: Discharging, 0%, rate information unavailable
Battery 1: Discharging, 88%, 02:01:52 remaining
Battery 2: Discharging, 0%, rate information unavailable

So it no longer is picking up the right battery (BAT1) and reading BAT0 or BAT2. Note: I only have 1 single battery (BAT1) in this laptop.

Could be due to changes in kernel or acpi ?

% uname -sr Linux 4.13.4

Note: having similar problems with battery.py from i3blocks-contrib and batterybar (this one shows status for 3 batteries when only 1 is present.)

Temp fix, changing this line from
open (ACPI, "acpi -b | grep 'Battery $bat_number' |") or die;
to
open (ACPI, "acpi -b | grep -v 'unavailable' |") or die;

fixes the issue for now but probably not ideal.

Having exactly the same trouble, the "fix" indeed works, thanks ;)

It's weird, extra batteries are only appearing after sleep on my PC (zenbook).

@archvill This could be distro specific, not sure. ACPI state changes on and off, etc. Ideally, the script would detect the proper battery (or batteries) and state changes dynamically. "Quick and dirty" fix above OK for now.

@stef204 agreed, BTW I'm using Arch.

The scripts are now exclusively maintained in the i3blocks-contrib repository, thanks!
