Thinkpad X1 battery change

I am helping a customer to change a battery pack in his ThinkPad X1. The FRU we ordered is 42T4977.

After the change the computer will not charge the battery. Entering Lenovo Settings application, i can see all the info about the battery and helth status is good.

 

If i change back to the old battery all works well.

 

What have i missed?

 

Lenovo ThinkPad X1

Type 1294-3QG

Re: Thinkpad X1 battery change

when doing any changes inside laptop allways use disconnect battery method in bios first so it fully disconnects it then replace battery and connect a charger and try with new one this might be why new one isnt charging due to your not disconnecting old one propertly.

Re: Thinkpad X1 battery change

I have performed the disconnect battery method in bios, step. The computer shut down and i swapped the battery pack.

Is there anything else i can do to determine if the battery pack is the problem?
