ThinkPad T470 Problems with recognizing hotswapped batteries

2017-08-26, 22:00 PM

When ever I disconnect/remove my 'external' battery pack and put it back in, I cannot find that battery for 30 to 60 minutes until it magically appears again.


Before hotswapping the battery

$ ls -l /sys/class/power_supply
total 0
lrwxrwxrwx 1 root root 0 Aug 26 22:16 AC -> ../../devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:19/PNP0C09:00/ACPI0003:00/power_supply/AC
lrwxrwxrwx 1 root root 0 Aug 26 22:17 BAT0 -> ../../devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:19/PNP0C09:00/PNP0C0A:00/power_supply/BAT0
lrwxrwxrwx 1 root root 0 Aug 26 22:58 BAT1 -> ../../devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:19/PNP0C09:00/PNP0C0A:01/power_supply/BAT1

After hotswapping the battery

$ ls -l /sys/class/power_supply
total 0
lrwxrwxrwx 1 root root 0 Aug 26 22:16 AC -> ../../devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:19/PNP0C09:00/ACPI0003:00/power_supply/AC
lrwxrwxrwx 1 root root 0 Aug 26 22:17 BAT0 -> ../../devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:19/PNP0C09:00/PNP0C0A:00/power_supply/BAT0

 I'm using a ThinkPad T470 20HE2SF00 with Arch Linux and Linux Kernel 4.12.8-2-ARCH
