i seem to be unable to charge my brand new razer turret keyboard and mouse using the included power brick and cable, the keyboard keeps going to sleep after 15min and stops charging all together even tho im using the included cables and power brick. ive updated the firmware on the mouse and keyboard both however im still having the issue of the keyboard going to sleep at the 15min interval. the only way to charge my device is when its connected to my pc, that is not the way this device is supposed to function, id like to be able to charge using the normal and faster method using the power brick. any help to solve this issue would be appreciated.
