NOTE:
If the error message indicates 3F0 error or Boot Device Not Found, determine if your PC has Optane memory installed and configured correctly. See HP Consumer Desktop PCs - Boot Device Not Found (3F0) or Automatic Repair Errors for desktops, HP Consumer Notebook PCs - Boot Device Not Found (3F0) or Automatic Repair Errors for notebooks. For more information about Optane memory, see HP PCs - Installing and Using Intel Optane.
While you check that out, have you reset the computer to release excessive static? Use Step 3 for steps.
Step 1: Remove external devices
If your Chromebook does not start, remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices (external hard drives and similar).
After you have removed all external devices, turn on the Chromebook. What happens?
-
If the Chromebook starts, reconnect devices one at a time while restarting the computer to figure out which device is causing the problem. You are done.
-
If the Chromebook still does not start or exhibits the same problem, do not reconnect anything, and continue troubleshooting.
Step 2: Find a fix that matches your Chromebook's symptom
If your Chromebook does not start, read from the following list of symptoms. If you find a symptom that matches your computer's condition, follow those instructions. You might be directed to another support document containing detailed troubleshooting procedures. If you cannot find a symptom that matches your computer's condition, proceed to Step 3: Perform a hard reboot.

P.S: Welcome to HP Community 😉
Keep me posted, as I (Or a trusted colleague) shall follow-up on this case to ensure the concern has been addressed,
And your device is up and running again, only in case you don't get back to us, first!
That said, If the information I've provided was helpful, give us some reinforcement by clicking the solution and kudos buttons,
That'll help us, and others see that we've got the answers!
Good Luck.
