Product: HP Pro Mini 400 G9 PC (4G4N7AV)
Operating System: Microsoft Windows 10 (64-bit)

I've been in touch with HP Support and they have gone through the usual diagnostic process and could not repair so organised an on-site repair (for two desktops with the same issue).

 

However there is a part (motherboard) supply issue and no ETA for arrival , so in the meantime I'd check if the community has come across the issue and has any ideas please.

 

If I remove the power and the CMOS battery, start it up, it'll work perfectly fine... until next reboot, where it will go in a constant boot loop with no ability to access startup menu, boot menu, diagnostics, etc... it'll reboot before it does.

 

I've tried factory reset of the BIOS and BIOS Security, tried three different BIOS versions (2.4, 2.6 & 2.7), I've tried removing the SSD and the issue still occurs.

 

Any suggestions would be greatly appreciated. Thanks
