When using my Razer keyboard my keys have started to move slower and even stick.
Slow keys may be the result of some kind of built up residue on them from food or dust particles. To check for this, pop out the key and check for any dust or dirt.
If the keys are being kept up when pressed, there is probably something underneath it. Pop the key off and check to see if there are any obstructions in the way. If there is nothing visible, there could be residue underneath the switches that is causing the keys to stick.
When I press the keys, nothing tends to happen.
The device could be incompatible with you driver. You can go to Razerzone.com to download the correct driver.
The device could be incompatible with your computer. The device can be returned to the retailer.
If there are the other options have been checked, then it could be a problem with the hardware. The hardware could have been damaged or it could not have been set right on he assembly line. It would be best to return the keyboard to the retailer.
While using my Razer keyboard, I've noticed that the LED lights are not turning on.
Plug the keyboard into the computer and determine if it is being powered or not. If there is power running through the keyboard, then the LEDs should turn on. If they do not, then there is not enough power running through the keyboard or it could be a hardware problem.
My USB cable will not work with my keyboard, but will work with other devices.
Plug the cable into something else that is compatible to it and see if the other device gets powered then it is not the cable. If it does not work, then it is the cable and you would have to order a new one or find one that is compatible with it.
If you plug the cable in, after you have tested the cable, and the keyboard is still not working, then it is the port that has a problem.
