1-5min after starting device background goes black and does not recover until reset.

Hp chromebook 11 

1-5min after starting device background goes black and does not recover until reset. However Taskbar stays visible and functional and when power button is held, a log out restores background visibility only long enough to enter password and log back in to a blacked out background.

It may be important to note that when the screen goes in to sleep mode and I hit a key to wake it back up the screen is visible again for a half second before returning to blank.

@CoryBankemper,

Welcome to the HP Support Community!

I reviewed your post and I understand that the computer is booting to a black screen.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps.

Step 1: Remove external devices

If the Chromebook does not start, remove any USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices including external hard drives and other similar devices.

After you have removed all 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 figure out which device is causing the problem. You are done.

• If the unit still does not start or exhibits the same problem, go to the next step to perform a hard reset.

Step 2: Perform a hard reset

A hard or forced reset erases all information in the computer memory. This 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.

1. Press the power button  and refresh  button for five seconds. The computer turns off, and then turns on again.

2. If necessary, press power button again to turn on the laptop.

3. If the issue persists, continue to the next step.

If you continue facing the issue, then continue troubleshooting from the below link.
