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].

Status in linux package in Ubuntu: Incomplete Bug description: I'm using a Lenovo T460s with two batteries running Ubuntu 17.10. The indicator shows the combined charge of both batteries and I was at 40% when the laptop simply turned off. After the reboot I saw that the main battery was at 88% while the extra battery was at 0%. For some reason the OS deemed it necessary to perform an emergency shutdown without any warning. I don't know whether this is a problem in gnome power management or the kernel but please, please find a fix for this! Or provide some workaround.
