Welcome to the Lenovo Community !
There are no Lenovo Training Videos available for your model, but there is a Hardware Maintenance Manual that will explain and illustrate how to access and remove the battery. Here is a link to that manual.....
Please keep in mind that if your warranty is still active, accessing the battery may void that warranty.

Not easy way... You have to open until the end. I am not sure why Lenovo want to make so hard to replace.
