HP Elitedesk 800 G3 SFF
Microsoft Windows 10 (64-bit)

Dear HP Experts

 

I'm using HP EliteDesk 800 G3 Small Form Factor Desktop computer. This computer gets shutdown after 2-3 days of operation. Now, I'm getting this alarm on the startup:

 

POST Fan Detection Errror

901- Chassis Fan Not Detected (Rear)

Press Enter to Continue

 

I opened the CPU cover but I see that the processor fan, graphics card fan and power supply fan were running. Then where is this rear chassis fan which is not getting detected? and how to fix this issue?

 

I believe that this unexpected shutdowns which im facing are also because of this problem.

 

Can you please help me out?

 

Regards
