The HP EliteOne 800 is HP's all-in-one desktop with a 23-inch diagonal screen.

Why won't my computer start?

My HP EliteOne 800 (unsure if it is a G1 or G2) will not turn on, no lights will turn on, or the screen is not showing any sort of responsive interface. It is making noises like it is running, but nothing is happening or it will not start at all and is completely unresponsive to all buttons.

There is a Display Port output on the back. You might use a separate monitor to see if the display system has failed. Here's a tip. Examine the screen very closely with a flashlight held up to the screen. See if you can see the screen image on the dark screen. It may be that it boots up OK but the backlight has failed.
