T460s - Battery 1 will not charge multiple failures on multiple machines in the last month

2020-09-17, 20:56 PM

We have been seeing numerous failures of the T460s primary batteries failing to charge.

We have already attempted the small reset hole option on the back.

One user was able/willing to remove the battery from the device.  This solved the problem for a couple days but it returned shortly afterwards.

When reviewing one of the users Device Manager I noticed that the system had "Microsoft ACPI-Compliant Control Method Battery" listed twice.  I disabled restarted reenabled - no fix.  Also uninstalled restarted - same issue multiple listings.

The Battery problem has been infrequent, and often times resolvable, on these devices until recently which leads me to believe there may have been a bad Driver.  I have noticed an increase in the number of BIOS drivers released recently.

Are those batteries Lenovo genuine, purchased with laptops or separately on Lenovo official stores?
