Remove the SIM card to ensure it doesn’t communicate with a cellular carrier. Then go into the settings for your specific WiFi network, configure IP address manually, and remove the entry for “Router” to prevent it from talking to the Internet

I think the special button on the keyboard is a fingerprint/lock button. Not sure if the computer supports powering on by pressing any key like the MacBooks, but it certainly will wake from sleep with any key.

You can use your own keyboard with it
