ProDesk desktop. 700/G4 I think but cannot currently verify. IWindows 10 64 bit. I have  been getting Product information not valid for a few years since a warranty MB replacement. Got it down to a few errors but do t much care at this point. Rebooted last night and now I can’t hit the space bar to continue boot. Tried 2 different USB keyboards and same issue with both. Can’t hit ESC or F11 for other options when booting. Or even Y to try to enter serial number, etc. Looking for suggestions.  No recent hardware changes. Installed Asphalt 8 or something from MS store yesterday and was playing that last night. Try to reboot every few weeks.

Try resetting the CMOS.  I was unable to find an HP product 700 G4 

 

The 400 G4 has a CMOS reset button. Some near the battery others  adjacent to a PCI slot

unplug A/C power, tap the power on switch a few times to discharge residual power,

touch finger to metal case then hold down the button (or remove the battery) for 20 seconds then re-assemble

Thanks for the response. It is a ProDesk 600 G3 SFF. I powered down as suggested, opened it up, blew out the dust ( I do this about once a month), and held the reset button for about 25 seconds. Took a second to start the stopwatch. Now I have it all back together, with one monitor and the USB keyboard connected. It took a few power button presses, but it appears to be working properly.  Thanks so much for the help. I truly appreciate ot!!

I am glad you got it working.  However, what you described should not have happened.  

Check warranty  https://support.hp.com/us-en/checkwarranty

some retail store have 3 year.  Your repair might have an extended warranty

 

Please run diagnostics:  press ESC after powering on and run at least one pass or a short pass.
