My HP Laptop battery has lost its settings

[Moderator BobC]

I switched the battery in my laptop, and ever since I have lost all current settings on it. It knows how big the battery is in mAh, but doesn’t know how much the battery will hold now when full or its current charge. I have tried 3 different batteries, and none show up correctly, even though all are good. I think reinstalling the OS will fix it, but that seems very harsh. The files showing “no such device” seem to be the problem. I have tried draining it all the way and rebooting, etc, but nothing seems to reset it. tlp recalibrate only works for Thinkpads, it looks, and this is an HP Pavilion dv9917cl. This did work fine initially.

Is there some way to reset the value when I swap in a different battery?

The battery is full, and although old, will hold the machine for over an hour. All the utilities like conky and xbattbar come up wrong with the similar wrong info as the acpi -bi

/sys/class/power_supply/BAT0# acpi -bi
Battery 0: Unknown, 0%, rate information unavailable
Battery 0: design capacity 6000 mAh, last full capacity -60 mAh = -1%

I have done lots of googling and found nothing that worked…

Any ideas on things to try?

When I run tlp-stat I get this:

+++ Battery Status
/sys/class/power_supply/BAT0/manufacturer = Hewlett-Packard
/sys/class/power_supply/BAT0/model_name = Primary
/sys/class/power_supply/BAT0/cycle_count = (not supported)

/sys/class/power_supply/BAT0/charge_full = (not available)

Did you find a solution?

In conky, the latest? way they call for battery info is:
Battery Level: ${alignr}$battery_percent%
–
Maybe replace the old call and see what happens.

–
I haven’t looked to find out what the behind the scenes code is, but maybe it will grab it. Never know.

Have you tried fully charging the battery, start the computer, enter bios setup (so it does not boot to your os) and just let it sit there until it runs out of power?

Then plug in the charger, and see if it has done anything or not

Well, it only lasted about 10 minutes. It did come back up happier, though, so what you suggested worked. I put in a different battery, and now my conky is working. You have to click it to see the battery part up near the top. It needs the acpitool and xbattbar installed to work…

#!/bin/bash
# conky-battery.sh - build battery string to return to conky
#   can't pass parm from conky, so get status byte from acpi -b (should be same as 1st char of battery_short), nothing comes back if not present
FILE='/home/bobc/conky-battery_0.tmp'
today=<code>date '+%Y_%m_%d__%H_%M_%S'</code>;
OUTPUT="$(acpi -b | tr '\n' ' ' | sed -e 's/Battery 0: //g')"
STATUS1="$(acpi -b | tr '\n' ' ' | sed -e 's/Battery 0: //g' | cut -c1-1)"
if [[ -z "STATUS1" ]]; then
	STATUS1=N
fi
#C is displayed instead of charging, D for discharging, F for full, N for not present, E for empty and U for unknown
case $STATUS1 in
	F|E|U )
		acpi -bi | tr '\n' ' ' | sed -e 's/Battery 0://g' -e 's/, rate information unavailable//' -e 's/ Full, //' -e 's/ full / /' \
			-e 's/ design //' -e 's/last capacity //' -e 's/ capacity / = /' -e 's/100% =/Full, Max/' -e 's/mAh,/mAh, Last Full/' \
			-e 's/Discharging,/Draining,/' > $FILE
		;;
	N )
		printf "Not Present" > $FILE
		;;
	* )
		tail -n 1 ~/xbattbar.log | sed -e 's/^.*\(line\:.*min\.\).*$/\1/' -e 's/line\: //' > $FILE
		;;
esac
cat $FILE

Howdy BobC,

Glad you found a solution that works. Also, . . Noticed you have weather on your conky . . any chance you’d be willing to share here?

I can’t seem to get any of the ones I find to work!

Ok, I can make a tar file of it. I think I’ll post it in the conky mods thread since that probably makes more sense.

I’m putting a piece of tape on each battery and marking it with what percent of capacity that battery has. That way when I swap I’ll know what to expect.

PS:Rust collector’s battery solution worked, but I can’t mark the thread solved

Excellent! Looking forward to it! The format was off a tad in my previous post. The link for conky-mods was right below where it should have been. Sorry for the confusion.
