Flashing Indicator Lights and No Backlight


Recommended Posts


I purchased a second hand K50 and it has been working perfectly for a few days now, although today when I turned my system on, the three indicator lights (scroll lock, num lock and caps lock) all began flashing and the backlight would not come on, I have been searching everywhere for a solution to this and have found that I may need to update my firmware or that the keyboard may be in 'BIOS mode'.

Firstly I cannot update the firmware as the firmware updater will not detect my keyboard and secondly I have no idea how to put the keyboard into or out of BIOS mode, please help me!

Thanks in advance for any replies!
