Lenovo Vantage PC running on Windows 10 Home.
W10 notification area is suddenly showing a sideways battery icon, saying "No battery detected". So I went to Device Manager but "Batteries" is no longer in the device list.
However, Lenovo's diagnostic software can still see the battery, reporting it just now as 80% charged. The battery is also shown working as normal when I run "powercfg /energy" from an elevated CMD prompt.
How can I get the battery back into Device Manager?
