I recently received my L14 and I am a big fan of the hardware.
Firstly, I encountered the same issue explained here:
My battery would get to 60-70% and then stop charging. I followed the instructions in this post and now the battery charges fully. I still don’t understand where the 60-70% number arises from the defaults of “start charging” when below 0% and “stop charging” when above 90%, but at least this issue is resolved.
The new issue is that when unplugged the laptop will suddenly crash with no warning or shutdown sequence. Initially this was happening at 20% battery, but today it has happened at 30% and 55%. Has anyone else encountered this issue? Does anyone have any ideas of a potential fix?
