Logitech K700 Keyboard Lost Dongle (the Solution!)

The K700 is a popular and cost-effective wireless Keyboard for use with Google TV and PCs.

The K700 uses a small black USB dongle that plugs into the TV. It needs this to connect.

The dongle is very small and easy to lose or forget. Many users will dispose or recycle an old PC and forget that the dongle was plugged into the USB port. In this post we answer some user questions.

Can I use the K700 without the USB dongle?

No, the K700 cannot be used without it. The dongle includes a wireless receiver that communicates with the keyboard and is mandatory for operation. The dongle will need to be replaced with another.
