I have a 8 month old Lenovo X1 Carbon (5th generation) which was originally running 16.04LTS.
When I upgraded to 17.04 I noticed the battery is no longer charging. When the AC is plugged in battery indicator / upower / Power Statistics all show the battery as "charging".
However the battery doesn't charge - it just stays at it's current rate (38%). Using the laptop when it's not plugged into AC just depletes the battery further.
I have tried three different chargers with the same results. I doubt there is any physical issue with the battery as the laptop is relatively new & the issue has only just started after the upgrade to 17.04.
Any help appreciated.
