To turn your computer on, press the POWER BUTTON (has a grey dot on it) located on the front right side of the keyboard.
NOTE: It may take a few minutes for your desktop to appear the first time you log on to your computer.
Your computer should launch to a familiar looking Desktop. All of your icons and files will be there, but any customizations you made to your last device (such as pinned programs or a custom background) will not carry over.
