HP Notebook 15 db0xxx stuck on HP PC HARDWARE DIAGNOSTICS UEFI

[SugaFoot979]

I had keys sticking on my keyboard so i go to YouTube to watch a video on how to properly clean your keyboard.. I had a couple of spills on my keyboard and i came across a product called Restoro ..  Somewhere in the process HP PC HARDWARE DIAGNOSTICS UEFI screen pops up .. it tells me the version number 7.6.2.0 and tells me that my current version of diagnostics is not up to date. i really need help i tried this before and i don't know if it actually worked or not my laptop finally opened normally but after 3 days of just leaving it alone and eventually had to unplug it..  so it worked fine until i shut it down one night and now it's back to this screen

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  
Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.
