How to make a new Microsoft Sculpt Ergonomic Keyboard work with a USB dongle from your old keyboard? Answered
I have my Sculpt Ergonomic keyboard ALT key fail from extensive use. I got my hands on an almost new keyboard which is missing a USB dongle.
The USB dongle and keyboard & mouse are a set and you cannot get a replacement. So the new keyboard did not work with the USB dongle from the old keyboard.
