Reset the keyboard. It sounds like demo mode.

To do a soft reset, Unplug the keyboard, hold the ESC key while plugging the keyboard back in.

you are a life saver. lights were on and changed mods itself but keys didn't respond, worked yesterday but today when i turned pc on keys didn't respond. what can cause keyboard to go demo mode?

It can sometimes randomly go into demo mode. But the usual case is when power is given to the keyboard but there is no communication between the computer after a certain time.
