Microsoft wireless keyboard not working all of a sudden it lost the signal what should I do I checked the batteries I am only 2 feet away from the computer i rebotted the computer the mouse still works fine 3000 v 2.0 model 1379

There are several different methods in resolving this issue. Before you perform these methods, make sure that the battery of your cordless mouse is fresh. Then, try this first method..
Method 1: Resynchronize your device with the receiver loadTOCNode(2, 'moreinformation'); To resynchronize the mouse or the keyboard with the receiver, follow these steps.
Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put any other wireless keyboards and mouse at least 6 feet away.

1. Press the button on the receiver, and then verify that the light on the receiver starts to blink.
   
   Note Some newer Microsoft devices are permanently bound to their receiver and cannot be reset. If your device does not have a button, skip to Method 2.
2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step.
3. Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.
5. For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.

The following example shows the buttons to push to synchronize a wireless hardware device


Method 2: Install the latest software loadTOCNode(2, 'moreinformation'); Download and install the latest Microsoft IntelliPoint and/or IntelliType software. For more information, visit the following Microsoft Web site:

I hope these works for you. Should you need the other methods, kindly reply for follow up. Good Luck!

Chances are that the keyboard is too far away from the receiver. This will wear the batteries down very fast. Optimal distance is less then 3 feet away unobstructed. try this and you shouldn't have many problems anymore.

Hi,

Look at the bottom of the keyboard for the "connect" button. Also press the connect button on the receiver.


Regards.

Decide where the keyboard will be placed, whether it is on your desk or a table. Spend a little time experimenting with positions and placement to make sure your wrists and arms will be comfortable. You should consider ergonomics before you set up the keyboard to avoid repetitive motion injuries later on.

Step 2 Install the batteries (usually three AA) in your wireless keyboard. Replace the cover securely so the batteries are connected properly. Turn the keyboard on.

Step 3 Get out the wireless receiver that came with your keyboard. Position it close to your computer, but not closer than about 8 inches, as the computer itself can cause interference with the wireless signal. You will also want to set the receiver away from other interference-causing devices, such as radios, TVs and telephones.

Step 4 Ensure that your wireless receiver is no more than about 6 feet away from where you plan to set your keyboard.

Step 5 Insert the CD containing the accompanying software into your computer. A dialog box should appear on your screen. If the install instructions don't pop up right away, manually access the CD by double-clicking its icon or selecting it from the Start menu.

Step 6 Plug the wireless receiver into a free USB port on your computer. If you don't have any ports remaining on your computer, you can use an external USB hub instead.

I don't know your level of technical experience, so some of these may seem obvious. These may not be in the best order, I've added them as I thought of them.
1) check the batteries in the keyboard and mouse. They can go through batteries in a big hurry sometimes. If just changed double check polarity.
2) check the connection(s) for the receiver. If you have pets check for chewed wires.
3) have you added any new USB devices. They may be using to much power from your USB ports
4) have you added any other wireless devices, includes non-computer devices.
5) have you tried resetting the keyboard and receiver signal.
6) check USB power output. You can plug in a different USB device and see if it works.
7) does your receiver require batteries (very rare).
8) you may need to reinstall your keyboard drivers and software.
Most wireless keyboards operate in the 400 Mhz range so do most wireless networks and many phones, these can all interfer with your signal.

Hello,

maybe the battery?
follow the steps below to troubleshoot the mouse
Wireless mouse does not respond (generic instructions)

Try to Resynchronize your device with the receiver(connector)
Follow these steps.:
Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put other wireless keyboards and mouse at least 6 feet away.
1. Press the button on the receiver, and then verify that the light on the receiver starts to blink.
2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step.
2. Press and release the Connect Channel button on the bottom of the mouse or the keyboard.
3. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 3 again.
For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.
or
Try different port and restart your computer.
or
Reinsert the batteries or install fresh batteries
If you have the possibility check whether the problem is because of your computer or the device, try the mouse or the keyboard on a different computer.

you have a resset onder the mousse, change the battery , and reinstall the driver

hey,
regarding the range i dont think its this less i mean 2-3 feet, mine works at some 5 feet also
Try replacing the batteries, if that doesnt help i guess the receiver is not able to receive the signals properly because of some obstruction. Try and put the mouse in clear sight of the receiver.
If still the problem persists.. check out your mouse range from its website.
Cheers

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.
