Keyboard resets after around 5 10 min everytime. and esc and F5 keys keep blinking. then all the other function keys also don't work. eg:0 I set keybpard brightness to something after 5 mins it resets to full brightness and nothing else works. I have to plug in again for the brightness keys to work. It's a new keyboard whats wrong in this? Can't raise a damn ticket because the website errors out everytime I submit. Pathetic service can't even maintain a freaking website. Can someone help? Is this a faulty keyboard?
