Omen 15 won’t boot up, caps lock blinking 5,3

[JL301]

I have an HP Omen 15-dh1070wm a little over one year old (literally only three weeks out of warranty) that won’t boot up after being put in sleep mode. It will turn on and I can hear the fan briefly start up, but the screen stays black. The caps lock light was blinking 5,3, so I tried a hard reset, which did not improve the error. I also tried opening the BIOS update screen using windows key + b + power button, but I only got the same black screen and caps lock code.

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did you make any changes to the settings of your PC prior to the issue?

If you have already performed the steps from the document HP Notebook PCs - Computer Does Not Start: https://support.hp.com/in-en/document/c01997899, No Power or no Boot and the issue persists, it could be a hardware failure.
