At the time I am writing this I have had the the GMMK Ten-keyless keyboard for 5 months. The keyboard has worked great until approximately 3 weeks ago. Currently, I am experiencing random shutdowns. So far, I cannot pinpoint a commonality amongst each time the keyboard turns off. Whether I am working in Excel, or gaming, the situation doesn’t seem to matter. The only consistency I can think of is I am typically on the computer for at least 30 minutes before it may become disagreeable. When the keyboard does turn off, I must unplug it, either at the pc or the keyboard, for it to revive. Does anyone know why the keyboard is randomly turning off?
