The 5BC000 - 5BDFFF region is all 0xFF. I could not find the Windows licence key either.
Does this suggest my eeprom does not contain this region anymore due to being flashed by someone else already?...

Thanks a lot.

Can somebody tell me where the DMI region is in this BIOS?
I just took a BIOS file from the official site. The laptop posts again. I still need to inject that region.

Perhaps, and something I will investigate. But as said, the issue occurs as well when running from battery. The smart pin should not be an issue then. Unless it is.

Self diagnose says the pin might be bent, which it isn't. Will check tomorrow for the exact message.
The laptop's behavior is no different with the adapter unplugged.

Hi,

I have an HP 15-ec2531nd here which does the following:
- Turns on. One of both fans goes full throttle. Other doesn't spin up.
- BIOS works.
- All self tests pass, except smart pin. Not even with another adapter connected.
- RAM is ok.
- RAM slot pins are ok.
- Battery is ok.

Whenever I want to boot Windows from m2 SSD system switches off.
I have a USB stick with several tools on it, including Windows PE. I can browse this stick's menu, but when I start Windows PE, the laptop switches off at the same point where it would...
