Morbiddk,     Power down the server, remove the power cords, then hold down the power button for 20 seconds, this will drain the flea power from the server. After that you will open the cover and then locate the NVRAM-CLR jumper, located near where the power supplies connect to the motherboard (as seen below), then move the jumper over and then add power back to the server to perform the NVRam clear procedure. Afterwards power down, drain flea power,  and then restore the jumper to its original location. This time you will reinstall the power cables, but wait 2 minutes before powering the server.    Let me know if this resolves the issue.    
I have a R720 that if I try to F10 at boot it gets stuck looping with Entering Lifecycle Controller... screen and only loads about 25% even after leaving it for hours. I finally fail the LCC and get the system to put it into Recovery Mode, but I'm sort of at a loss as to how to fix this. I've tried doing the LifeCycle Controller Repair Package in iDRAC but I get an error; RAC0613: The uploaded file is invalid. Make sure to upload the required file in the correct format and retry the operation. At boot the system reports BIOS is version 2.8.0 but in iDRAC it shows 1.6.0. Below are my LCC and iDRAC vresions. LCC: 2.63.60.62 iDRAC: 2.63.60.62 I can say that I have Inventory Collection currently disabled because it only gets about 50% complete and never finishes. TIA
