Spectre x360 Folio will not boot (5 long & 3 short flashes from Caps Lock light)

[K20FTY]

My Spectre Folio will not boot up, I get 5 long and 3 short flashes from the white light on the Caps Lock Key, which helpfully tells me to 'Contact HP support if the issue persists'.  The device is approx. 3 years old, and has only been lightly used.  I've tried the WinRE reset (on/off/on/off/on) - the system doesn't even get far enough to run diagnostics.

If I allow the battery to drain completely, and then plug into adapter it will boot into windows very briefly, and then freeze (no cursor or keyboard input accepted), the screen will then begin to flicker for approx. 10 seconds, and then goes dark and stays that way.  Every subsequent attempt to start up just gives the 5 long and 3 short flash sequence.

Any input / thoughts gratefully received!

Hi @K20FTY,

Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you.

I see that you are facing boot issues with your HP Spectre Folio - 13-Ak0000na.

Please follow the steps listed below for BIOS recovery:

1. Turn off the computer and keep the power adapter plugged in.

2. Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

4. The HP BIOS Update screen displays, and the recovery begins automatically. Follow any on-screen prompts to continue the start up to complete the recovery.
