[Bug 1748747] Re: Laptop turns of when secondary battery is empty while main battery is still charged.
Apparently it is known for quite a while (read 6 years) that UPower has some problem with dual battery systems: https://bugs.freedesktop.org/show_bug.cgi?id=55278 ** Bug watch added: freedesktop.org Bugzilla #55278 https://bugs.freedesktop.org/show_bug.cgi?id=55278 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748747 Title: Laptop turns of when secondary battery is empty while main battery is still charged.

[Bug 1748747] Re: Laptop turns of when secondary battery is empty while main battery is still charged.
Joseph, since I am using the laptop as main working device I am very reluctant to switch from the ubuntu custom kernel to mainline and let the machine die willingly. I got a pointer via AskUbuntu (https://askubuntu.com/questions/961278/how-to-prevent-shutdown-when- one-of-two-batteries-is-empty) that UPower is likely to be the real culprit (https://forums.lenovo.com/t5/Linux-Discussion/How-to-get-dual- battery-to-switch-without-powering-off-in-Linux/td-p/3890605). I will now tell UPower to warn instead of shutting down, turn on the gnome power management again and check whether the problem stays. If that is the case I will go ahead an run 4.16 :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748747 Title: Laptop turns of when secondary battery is empty while main battery is still charged.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.16 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
