Power Off: Completely shut down the tablet. Button Combination: Hold down the Power Button and Both Volume Keys simultaneously. Logo Release: Once the tablet vibrates and the Lenovo logo appears, release the Power button but continue holding both Volume keys. Wipe Data: Use the volume keys to navigate to Wipe data/factory reset and tap the Power button to execute.
