Restart your ASUS laptop and press the "F9" key while the computer is booting up. This will open the boot screen. Select "Recover Windows to Entire HD" and press "Enter."

Press "Y" three times when asked if you are sure that you want to restore. The laptop will restore the factory settings. The computer will then shut down and start up again.

Approve the license agreement, then select your "Language preference." Enter your name into the box and click "Next."

Enter your password twice on the next screen and select "Next." Enter the time zone and date information, then select "Next." Select "Finish" on the next screen and the computer will reboot.

1. When the phone is powered off, press and hold the Volume Up and the Volume Down keys both at the same time, then press and hold the Power key until a test screen that shows some available options appears, usually takes about 15-20 seconds. When that screen pops up you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights FACTORY RESET then press the Power key to select it.
2. Power the phone off all the way, press and hold the Volume Down key and press than release the Power key, still holding the volume down key for about 10-15 seconds. When you see some additional options pop up on the screen you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights the reset option; it usually says FACTORY RESET, then press the Power key to make the selection.

Factory reset is your best bet.

The Slate doesn't have any sort of video output. The only thing you may be able to do is run a DLNA server on the device that you can connect to watch videos.
