Hi, I am using a t440s thinkpad with Arch linux installed on it. The external battery was working fine at first but recently it refuses to discharge first. The internal battery discharges then shuts the computer down when its empty leaving the external battery at full charge.
Running acpi -V on my computer it outputs the following:
Battery 0: Unknown, 100% Battery 0: design capacity 6039 mAh, last full capacity 5672 mAh = 93% Battery 1: Discharging, 98%, 02:16:50 remaining Battery 1: design capacity 1924 mAh, last full capacity 1767 mAh = 91%
Battery 0 is my external battery and is labeled as unknown. I updated the BIOS to the latest version and this did not fix this issue.
Solved! Go to Solution.

You are likely going to be able to find more assistance in the Linux Discussion (https://forums.lenovo.com/t5/Linux-Discussion/bd-p/Special_Interest_Linux).
A good place to begin your research may be into acpi_call and tlp .

Thanks, I installed winows on the computer and experienced the same issue. After some further research I have come to the conclusion that the battery is faulty and will be replacing it.
