Enter BIOS SETUP.

 

Look for a setting to disable the motherboard from trying to monitor that specific "chassis" fan.

Once it is set to "ignore", the error-message will not be produced.

F10 doesn't give an option and I think HP has bios blocked from entry

As soon as you turn the computer on, is there any white-coloured text on the bottom row(s) of the screen, showing which F-keys do which function?  Or, do you need to immediately press ESC to view that text?

You think, or you know? 

 

Did you purchase the new motherboard directly from HP, or did the previous owner "block" it, with a password?

Sorry yes this is a refurbished board the bios is not blocked that I know of but F10 takes you to the Hewelett Packard set-up menu not the Bios to do the changes you suggest is there another way to get Bios set-up because the HP setup utlity has nothing like that my understanding is HP will not allow acess directly to the BIOS Paul and I discussed that in an earlier post for another situation

Whatever HP names their motherboard "configuration utility", I would hope that it allows enable/disable of the monitoring of a chassis fan, and to change other settings, such as "if the power goes off, and comes back, the computer should either STAY OFF or RESTART", or "schedule this computer to automatically power-on at 2 AM on every Sunday, so that a RAT (Remote Administration Tool) can push updates", or "disable integrated video if a PCI-E video-card is added".

 

What does F10 allow you to set?

 

 

Of course, if you install a working chassis fan, the error-message should not be produced.  :generic:

Unfortunately, the BIOS is locked down.

 

 

As per above Paul has told me that Bios are locked down in HP desktop computers only the HP set-up is avaiable in F10

F10 is basic not muck able to be changed in settings the refurb board was installed in a working hp 6000 pro chassis the fan was never changed and it is working as we text everything is working except for the error message I've even reset the Cmos to factory setting and did the same thing in F10 still get the message and have to press f1 at boot.

> rear chassis fan not detected.press F1 to boot. The fan is working great.

 

Some computers have both a "rear chassis fan" and a "CPU fan".  Does yours?

 

Check the wires that run from the labelled connectors on the motherboard.

One connector will be labelled "chassis" and one will be labelled "CPU".

Make sure that a fan is connected to the "chassis" connector.
