You may need to press a button on the bottom of the keyboard or on the reciever portion to get it to reconnect. It will be a very small button, probably about an eighth of an inch, that appears level with the surface surrounding it. Use a straightened paper clip or ball point pen to press it. A pencil contains lead that could cause an electrical short between contacts, so don't use a pencil.

It could be a drivers problem... Unistall the drivers from the device manager and install a fresh one from the dell website.. Try pressing the FN+F2.. Still no go.. Try to check whether the keyboard is working.. Still no go - resaet the Wireless card... Still no go.. Replace the wireless card..

My Dell RT7D40 won't sync with my computer. do i need a CD? my computer is old and doesn't have a sync button on the back. does this affect my keyboard?


Blue tooth is notorious for not working. Your best bet for a worry-free life with your computer, is do not use wireless kbd or mouse. sincerely, they are all hype, and no real benefits come from their use. Youd be better off using USB extension cables to reach into those odd places rather than spending hours and hours of time trying to get something to work, only to discover that as soon as windows updates itself, it has failed and, (once again) you have no kb or ms control and the computer is just sitting there waiting on you to do something, but you cant. wireless kb and mice are a pain, and they eat batteries like pac man eats dots.

Dell Wireless Keyboard stopped responding, please help.


The keyboard should have a button underneath it. Press the button on the usb controller first and then the button on the keyboard. Repeat a few times to see if it connects. If you are still having trouble try another set of batteries as some batteries are not designed for wireless products.

Dell Wireless Keyboard interference


with that kind of distance the likelihood of having the keystroke signal picked up by another computer is very small even under ideal conditions. Even using a bluetooth wireless keyboard you're only "optimal" within about 30 feet.

Without the bluetooth setup i don't believe there's a way to connect the keyboard only to the one computer. Your best bet for a solution is to move them as far away from eachother as practical. Repositioning the reciever on the effected machines so they're less likely to pick up a signal further away (lower, and closer to other electircal / electronic equipment) should help as well.

Keyboard not responding


The keyboard has probably died. (It happens often). Here's a great inexpensive combo to replace your current one. https://www.amazon.com/Logitech-MK270-Wireless-Keyboard-Mouse/dp/B00BP5KOPA/ref=sr_1_1?ie=UTF8&qid=1491364851&sr=8-1&keywords=Logitech-MK270-Wireless-Keyboard-Mouse
