Microsoft wireless keyboard 850

Hello
DawidKwiecień1,

Good day!

So sorry to hear that you lost your USB trans-receiver of your Microsoft wireless keyboard 850.

You have to buy a new set of the Microsoft wireless keyboard 850, you can not buy only the USB trans-receiver for the Microsoft wireless keyboard 850.

Regards,

 

Windows wireless keyboard 850 update

My Microsoft 850 wireless keyboard and mouse have been working for the last 2 years on Window 8.1 with no issue. Today Windows asks me to update my wireless keyboard driver. I download and install MS Wireless Keyboard 850 Update and Mouse and Keyboard
Center 11. Run MS Wireless Keyboard 850 Update steps until it asks me to remove the battery from the keyboard without any issue. Put the battery back in, hit a key on keyboard as it asks. Nothing happens. Mouse and keyboard are dead. Unplug and plug the USB
receiver back in, Windows prompts "the USB device not recognized". Plug the USB receiver to another computer, get the same "the USB device not recognized" error. I try to be a good user but Microsoft wireless keyboard update fails me. Sad. What can I do to
fix this? Thanks.

Hi lbnoell,

Thank you for purchasing the Microsoft 850 wireless keyboard and mouse. Most wireless keyboards does not have LED indicators for "NUM LOCK" and "CAPS LOCK" to save battery life.

If you really need to have some sort of indicator for the "NUM LOCK" and "CAPS LOCK" we suggest to follow the suggestion of DR HARISH LRAO on a similar post. Here's the link: Redirecting
