Lenovo Yoga 2 11 plugged in (but not charging) potential driver issue
Hi everyone and hello to the forum.
I have got a Lenovo Yoga 2 11 with Windows 10 that at some point stopped charging and ended up with a totally flat battery. Still runs fine on the mains though. As the battery was old and weak anyway I replaced it. New battery battery was pre-charged and worked well - unfortunately it didn't charge either. It is drained and the battery icon shows ( 3% plugged in ) and nothing happens.
After a lot of searching and reading it is either your charger or your battery I came across the hint to uninstall the Microsoft AC Adapter as well as the ACPI-Compliant Control Method Battery. Then unplugging it and removing the battery for a little while.
As a result the battery charges for a few seconds upon restart then stops.
Running a battery monitor show the system voltages increases slightly and some mA going in before it stops.
Windows says the drivers are up to date. And I can't find a previous driver version from the Lenovo site or else.
To me it looks like this is not a hardware issue.
Anyone got some ideas what I can do?
All input kindly appreciated.
