HP Z240 Tower Base Model Workstation
Microsoft Windows 11

Hello,

To upgrade my GPU, I replaced the power unit more powerful (Corsair 750 W)  and an adaptator for this HP motherboard.

https://www.amazon.fr/gp/product/B0758CT3VM/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Since then, I have a POST error during the boot :

Fan detection error.

90E-Power supply fan not detected.

Power supply fan is not connected or may have malfunctioned.

 

However, all the fans work well.

I push enter and the boot continues without problem.

I didn't find some parameter in the BIOS to disable this error.

@ttb211,

 

No. Either you find a way to modify the "P2" wiring, or you'll have to live with the POST message.

 

Again, this adapter wasn't made for the Z240.

 

Kind Regards,

@ttb211,

 

Welcome to our HP User Forum!

 

This power adapter isn't specifically made for the Z240 -only the Z220 and Z230. The fact that it works at all and as good as it does, is nice to know.

 

However, I wouldn't worry about the POST message.  As long as everything powers up, and the cooling fans are revving up when your processor heats up, you are good to go.

 

Perhaps some modifications to the "P2" connector can be made, but if I were you, don't bother.

 

Kind Regards,

Hello,

 

Thank you for your answer.

But is it possible to disable this message in the BIOS ?
