RobertSeattle2,  Have you updated the server to current? It may be a case of the EMC/Drac being out of date or the BIOS.  If that doesn't resolve then you can also disable the "Report Keyboard Errors" in the BIOS and the prompt shouldn't come up again. Let me know how it goes. 
I have a dual power supply T710 which is no longer reading power consumption info from the systems board and thus at every reboot is requires a F1 key click to continue after a bogus "too much power demand" warning.   System is pretty close to replacement time but just curious if there are any known workarounds to this.  System is working fine otherwise. 
4 Year old T710 no longer getting Power Consumption info
