Battery replacement procedure for current lenovo modelsaa

Hi,

Here is a link to the service manual for your device.

Scroll top p.35 for the procedure to remove the battery pack.

On p.59 you will find the part numbers for the battery. Select the one appropriate to your device and Google just the number (do not add Lenovo or battery to the search term) to find suppliers of the part.
