HP Spectre x360 15-bl012dx BIOS needed

[survivalbloke]

Upon pressing the power button, all that happens is immediately the fans spin on high. It will sit and do that indefinitely until a hard power-down is performed. No video, no post, no nothing.

Model# 15-bl012dx
SN# 5CD7246XYQ
Prod# Z4Z35UA
Board# DA0X32MBAGO REV: G

You have backed up the wrong chip. That is thunderbolt firmware.

ok, I'll have another look, ty.

Is it this one? This is the only other BIOS-looking chip on this side of the board. Perhaps it's on the bottom side?

No. Google search the part number of the chip Z2023PI https://www.aosmd.com/res/data_sheets/AOZ2023PI.pdf

Interesting, I searched for that on alldatasheets but it didn't pull up correctly. I think I found it up by the CPU. It's Winbond 25Q64. That must be it. I'll be back with the backup. Thank you SO much for the help.

Try
DMI+WINKEY @ 61BF00-63DF3F

DMI+WINKEY @ 61BF00-63DF3F

I feel really stupid. Is that a repaired BIOS you've attached? I presume it is, so I'll go ahead and flash that, and thank you. I'm a bit confused on the second part. I've searched a bit and discovered DMI is the HP app to install the serial number, etc into the firmware, but what do you mean by "WINKEY @ 61BF00-63DF3F"? It's tough hanging with the big dogs on here lol.

WINKEY - windows key

WINKEY - windows key

but what does "@ 61BF00-63DF3F" mean? What are the instructions? I'm not experienced enough to understand, but I'll remember once I'm told.

the range in which the DMI+KEYWIN information is located

[survivalbloke]

the range in which the DMI+KEYWIN information is located

OHHHH, so then, I would:

1. Open the original BIOS in a hex editor
2. Copy everything from 61BF00-63DF3F
3. Open new BIOS file
4. Paste that info into 61BF00-63DF3F
5. Save the BIOS file and flash to chip

Correct?

Hey, supposing the instructions I listed in post#13 of this thread are correct, I did that but the device does the same thing. I power it up and the fan spins high, nothing else happening. Cooked board you think?
