1. First, click the Start menu in the lower left corner of the computer screen, and then select the Settings option on the right side of the menu bar.
2. After entering the setting interface, click the system option above, and then select tablet mode on the left interface.
3. In the tablet mode interface, click the option when I log in, and then select the option below to automatically adjust the appropriate mode according to my hardware.
4. Then adjust the option to use tablet mode, and then return to the desktop.
After Lenovo's tablet mode is turned on, you can control the computer by touching the screen, which can temporarily replace the keyboard and mouse. And in the process of starting tablet mode, the application on the computer desktop will open in full screen mode, thus reducing the taskbar and icons on the desktop.
This answer applies to most models of Lenovo computers.
