PowerEdge R720 slow bios and time clock stopped

We have a Dell PowerEdge R720, suddenly when we book the bios booting take too much time, very slow and it has a message that says time of day no set please rum setup, after minutes it gets stuck on press f1 to continue of f2 to enter setup...  The keyboard just won't work and can't do anything,

What to do? Why the booting so slow?

If it is an older server you may want to look into replacing your CMOS battery to avoid time issues. The USB drive will causes all kinds of weird issues if they are plugged into older equipment. Glad you figured it out!

The server is Brand new (it has like 6 months), it wasen´t the battery, it was a usb drive that was making all the booting conflicto.

Thank you anyway! :D
I got the exact same problem on R720 with slow BIOS and error of 'Time of Day not Set'. It didn't help by replacing motherboard battery and power supply modules. It is finally fixed by fixing USB error in device manager. I just simply disable the USB device got problem; and it got normal after restart. Very good solution by above posts; thanks!
