HP Chromebase features a 21.5 inch BLACK SCREEN

This thing will not come on. The power light is on but it is not working just a black screen. Help!!! Black screen that’s all.

Hi @KamZilla,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Is your PC powering on?

Are there any lights blinking?

• Meanwhile, 
  
  Remove external devices
• If the Chromebook does not start, remove all nonessential devices including external hard drives, keyboard, mouse, USB devices such as hubs, and memory cards.
• After you have removed all the external devices, turn on the Chromebook.
• If the computer starts, reconnect devices one at a time, and restart the Chromebook each time you connect another device to determine which device is causing the problem.
• If the unit still does not start after all the devices have been removed, go to the next step to perform a hard reset.

Perform a hard reset

• A hard or forced reset erases all information in the computer memory. A reset also forces the system to clear and reestablish the software connections between the BIOS and the hardware.
• A hard reset does not remove any local files or settings.
• Simultaneously press and hold the Power button and Refresh key for five seconds.
• The computer turns off, and then turns on again.
• If necessary, press the Power button again to turn on the Chromebook.
• If the issue persists, continue to the next step.
