To get to the battery in the Yoga Book X90F you will need to review the guide on how to remove the bottom screen/keyboard. Once the bottom screen is removed all you need is a pair of tweezers and a pick to wedge the battery out with. The battery can be diagnosed with the following troubleshooting page.
The battery provides power to the device, and a poor battery will not perform tasks on the computer well or for very long.
Prior to starting the replacement, please turn off the power on the device and disconnect any external power sources, such as the device charger.
Use caution when removing the battery as it may begin to bend and crack when prying off the board.

While the screen is lifted, insert the ifixit opening pick to help pry off the screen.

Make a plan to replace the keyboard/second screen after installing a replacement battery.
How to calibrate the battery?
I like how the screen is broken in the pictures from step 1 to step 2. :P
Thanks for the writeup! too bad the cost of replacement parts make this repair almost not worth the effort. =(
Excellent but i find nowhere an explanation of how to reassembly, mainly how to adhere the keyboard glass surface to the base chasis. I mean, is still usable the same original adhesive heated in the first step or a two sides adhesive frame has to be placed after removing the old adhesive (or just aplying a sort of glue -¿wich one?-). I’ not sure I’ve made it clear, I hope yes. Thanks in advance.
