Thinkpad T470 removable battery not charging

Hello everyone,

 

I just got a new thinkpad t470 and am very happy with it except that the removable battery won't charge. The battery indicator in windows says:

 

Battery 1: %0 and charging

Battery 2: %100 and fully charged

 

Lenovo vantage shows the following:

I tried turning it on and off and removing the baterry,

I reinstalled Lenovo Vantage,

I used lenovo selution center but came up with nothing.

 

In the beginning it also gave me popups saying that battery 2 wasn't recognized and lenovo vantage woud show 'error' in the details of battery 2 but that went away after the reboots.

 

any suggestions on what I could do?

 

thanks

If reported voltage is correct, 8.1 V is too low to start charging. If you have warranty (should be 12 months for battery), you should RMA it.

BTW, was it empty for some longer period?

Re: Thinkpad T470 removable battery not charging

thank you fo your reply, 

 

I think I'll RMA it. 

after I updated windows it did charge to 10%. The voltage now shows 11.09v, but it stopped charging again.

 

The battery was empty when I got it. I don't know how long it has been sitting on a shelf with an empty battery.

I have the exact same problem with my T450S and it's out of warranty. 

 

I even tried doing a new Fresh Install of Windows 10 but the problem persist

 

I uninstalled the battery in Device Manager but the problem still persist

 

I also installed the May 13 2018 Lenovo power management driver but the problem persist.

 

When I check the "Details of the battery driver" in device driver it as Microsoft - 2006. 

 

Battery 1 (internal battery) is working fine.

 

HW Info says batter 2 has a wear level of 26% and the voltage is 5.9V

I called lenovo and they send me a new battery that is working fine now. I suggerst that you try buying a replacement battery.
