Lenovo ThinkPad X1 Yoga 20LD Hardware Maintenance Manual page 50

Notebook mode

Tent mode Tablet mode
The X1 Yoga has an improved rise-and-fall keyboard mechanism that works with the four YOGA Modes.
• As you open the display into the Notebook mode, the keys are deployed, rising into the typing position.
• As you rotate the display further back into the Tent, Tablet, and Stand modes, the keys retract into the
body of the computer, providing a flat surface to hold and protect the keyboard when not in use.
Because of this rise-and-fall mechanism, you might notice some additional resistance as you rotate the
display among these four modes. You may also hear a sound as the keys are moving into and out of the
typing position. Both the resistance and the sound are normal and reflect the rise-and-fall mechanism during
the display rotation.
