With no working power button or LEDs, I would suspect an EC issue. Have you
examined what the dumps contained?
Cleaning ME doesn't help (I found that out too). I'm also going to assume
that your laptop has neither Boot Guard nor HP SureStart (as I understand,
Boot Guard implemented in the EC?)

For some time now I've been trying to port my laptop with no luck, yet.
Here's what I did:
• I recovered all the log's from the system, as per
• Took apart my laptop and dumped eeproms via soldering off, it appears I
have w25q80dv - 8mbit
<https://www.winbond.com/resource-files/w25q80dv_revf_02112015.pdf> and w25q64fv
I made sure the dumps are valid, doublechecked via diff and purged the
eeproms, system booted normally when I flashed the dumps back.
• I made an amature coreboot config based on Mimoja's Razer Blade Stealth
(2016) H2U <https://review.coreboot.org/c/coreboot/+/34475> which is now
merged. I failed in adapting *devicetree.cb* and left it as is. The
laptop showed no signs of life (dead PB and no lights) after externally
flashing w25q64fv - 64mbit
with coreboot combined with original *Descriptor* and stripped down *ME*
via nconfig (probably should not have done that for 1st boot). Flashed the
dumps back, no bork just yet =)
• I have yet to create a position on Gerrit <https://review.coreboot.org>.
*P.S. not including the eeprom dumps, too heavy for a public mailing list.
Will send on demand.*
I would be glad to receive any help, please do guide me.
