Title: natacpi bug in 4.18.0-16-generic, fixed upstream 5.0.2 Status in linux package in Ubuntu: Incomplete Bug description: low-impact bug, easy workaround. Thinkpad T480 4.18.0-16-generic Bug: # cd /sys/class/power_supply/BAT1 # # echo 95 > charge_start_threshold bash: echo: write error: No such device but it works for BAT0 It means tlp, latest version installed via PPA, by default can't set battery charge thresholds for the second battery in ubuntu 18.04 because tlp now defaults to using natacpi. This can be reverted to the old way of working via a simple change in the tlp conf file. This bug is fixed in 5.0.2 installed from ubuntu mainline ppa. I did not try earlier. ----- root@moncrief:/sys/class/power_supply/BAT1# cat /proc/version_signature Ubuntu 4.18.0-16.17~18.04.1-generic 4.18.20 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1820796/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
