I have HP ProDesk 600 G3 Mini I was getting an error message that the CPU fan was not working or disconnected. But you could hear the fan working.  Unplug the unit and opened it up everything looked fine when I plugged it back in I got an error message that the time and date where wrong and the CMOS battery could be bad. I replaced the CMOS battery restarted the unit set the time and date. 

Now the computer will not boot from my Samsung SSD 850 EVO  it had been booting fine. I get the error message Boot device not found Hard Disk-(3F0). I reinstalled the original hard drive(old school) it boots just fine.

I don't  know if my SSD drive is bad or is there a setting in the CMOS that I'm missing keeping from working

Hi @theabbott 

 

The Samsung 850 EVO should work as expected after replacing the CR2032 MB battery.

 

A 3F0 error usually means the disk may have failed or the bootloader is corrupted.

 

Try running HP Diagnostics to check the 850. Start the PC. Tap "ESC". Select "F2". Run drive tests. Also run component tests. Faulty RAM can throw multiple error messages.

 

Connect the 850 to a different PC as a data drive to back up stuff if you can mount this disk.

Fix it turned off secured boot in CMOS and it booted right up

Hi

 

That's interesting.

 

Secure Boot usually affects new graphics cards or drives containing untrusted bootloaders.
