Logitech Ex100 - Wireless Keyboard and Mouse not working? Read on..
Today for some unknown reason suddenly my Logitech Wireless Keyboard and Mouse - Model Number EX100 (Logitech Cordless Desktop EX100 (920-000879)) stopped working and very stubbornly denied to work despite my repeated attempts on all obvious and logical steps - resets, battery change and such.
After trawling through the internet for some time I figured that I am not alone in facing the issue but surely have been hit quite late by it. It appears Logitech was more than happy to replace it at one point.
