First and only battery on linux isn't always BAT0

[luzader]

The battery on my laptop is "BAT1" and there is no "BAT0". So this check will fail:

psutil/psutil/_pslinux.py

Lines 1220 to 1221 in f0094db

	root = os.path.join(POWER_SUPPLY_PATH, "BAT0")
	if not os.path.exists(root):

It's possible this is an oddity of just my laptop (it doesn't have a second battery bay or anything exotic), but I wanted to point it out in case perhaps this is failing for others.

This should now be fixed. Thanks for the report.

@giampaolo Hello. I think it is not worthy opening a new issue, just to report that psutil could not detect the battery on my Atom-X5 convertible, but thanks to this issue I was able to make it work by searching for BA instead of just BAT (the battery is called BAPM and the adapter is ADP1).

psutil/psutil/_pslinux.py

Line 1341 in 40abe5c

bats = [x for x in os.listdir(POWER_SUPPLY_PATH) if x.startswith('BAT') or

$ pwd && ls
/sys/class/power_supply
ADP1  axp288_charger  axp288_fuel_gauge  BAPM
