This article will walk you through the experience of taking your Dell XPS 12 9250 tablet out of the box and starting it up for the first time.
Locate the AC adapter and the USB-to-USB-C cable that came with the tablet. Plug the AC adapter into a power outlet and plug the USB-C connector into the port located on the left-hand side. Because the battery may have discharged during shipping, it may be necessary to charge the battery before starting up the tablet.
The tablet orients horizontally with the webcam at the top. The power button is located on the right-hand edge close to the top, and the Windows button is located in the center under the screen. For more information on the ports and features, refer to the XPS 12 Quick Start Guide on the XPS 12 Manuals Page
To turn on the tablet, press and hold the power button for 3-5 seconds, then release the power button. It will take a few seconds for Windows to launch.
NOTE: When booting the tablet for the first time you will be taken through a series of screens to setup Region, Language and to create or sign into your account among others things.
