p6-2133w chassis fan

[Segfault]

Is there a way to bypass fan check at boot? I do not want the chassis fan running and it is not needed, the box is cool enough without it. However, it does not boot, it sits there waiting for F1 to be pressed. But there is no keyboard connected ... the machine is headless.

Thanks for reply! There is no such menu item, unfortunately. The BIOS upgrade download is an exe file, what I am supposed to do with it?

@Segfault, thanks for your response and time.

Thanks for trying out the steps.

As you mentioned you don't see options in BIOS.

I had a cross check from my end. Go to BIOS select power tab, select thermal from the list.

Select system fan speed and make it to 0.

Press F10 to save changes and exit.

Hope this helps have a great day ahead! 🙂

Yes there is a menu item with fan speed. It shows 0 RPM - because the fan is not connected I guess. I hit F10 from there and exit with save. No change, still error 512. Meanwhile i tried to get the binary out from exe file, no success.

 ~/downloads $ file sp69356.exe 
sp69356.exe: PE32 executable (GUI) Intel 80386, for MS Windows

Tried to unzip.

 ~/downloads $ unzip sp69356.exe 
Archive:  sp69356.exe
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of sp69356.exe or
        sp69356.exe.zip, and cannot find sp69356.exe.ZIP, period.

Why it is made so difficult?

@Segfault, thanks for the response.

Thanks for your quick response and time.

As you mentioned you still get 512 chassis fan error on your PC.

Either connect the rear fan to the motherboard or use the optional left side mounting for the original fan. If you use the rear fan, be sure to set the fan to max speed.

Right click on sp69356 click run as administrator and check if it helps.

If the issue still persists it is a hardware issue please contact HP support for service options.

Have a great day ahead!

Take Care! 🙂

I cannot click on anything, I do not have GUI installed. And I doubt it would run even if I had. I find this BIOS upgrade most user-unfriendly. 😞

@Segfault, thanks for your quick response.

Try restoring the BIOS on your PC and check if helps.

Refer this article to know how to restore BIOS.

Let me know if this helps!

Have a great day ahead! 🙂

@Segfault,

Would this help?  It's a year old discussion on ERROR 512, and a fix.

[Segfault]

Thanks! This is promising indeed. Will get on this as soon as I get a chance. I was already considering using two resistors to get some voltage on control pin to cheat out from this error. 🙂
