    My MS Wireles Desktop 4000 keyboard is not responding at all and most times gives a keyboard error before booting up with or without the USB to PS2 adapter, so I am dead in the water. The wireless mouse that came with it is working. What I have already tried: Sofware is installed, I do see a steady green light on the receiver, I have held the channel button down after pressing the receiver button (thought not sure if that is the right way to do it, and the batteries have been checked/replaced. I borrowed a keyboard and have to use that for now, but I really want to make this ergonomic MS keyboard work as I have a cyst on my wrist that hurts with regular keyboard usage. HELP!

    Uninstalled everything and tried again

    Didn't work (Both the keyboard and mouse).

    I'm having the same problem with my MS Wireless Laser 5000 Keyboard. The mouse works fine. I changed the batteries in the keyboard but still no help. I tried everything I've read to help including updating the driver. I guess I go out tomorrow and buy a new keyboard. dang...not seeing anything that offers help.
    good luck everyone!

    I am sick of this keyboard. I get lot battery and low signal strength messages even with new batteries. I sometimes have to reset the connection half a dozen times a day. I love the keyboard's comfort but have had it with not being able to type. Mouse always works.

Erm guyz.... I need an urgent response on this one plz... So I bought this microsoft wireless desktop 5000 wich is just great... was! Two days ago, my mouse starting acting up... Basically, my mouse pointer doesn't follow the trajectory I draw up on the monitor... For example when I move the cursor from one side of the screen to the other, the arrow will stop at half the distance... Until then, I haven't installed any drivers, since this was working fine as a plug'n play device... After this, I also installed the driver, but it was of no use... I also attempted to re-establish the connection between the mouse and the receiver... No good.... Didn't change anything... Yet my keyboard works perfectly and all the batteries are fresh... Please guyz.... I am really desperate.... At one point the arrow wasn't moving on the screen at all though I was heavily moving the mouse...

Ok I just recently got the same problem AGAIN for the 5th time. Don't worry this is very possible to fix.

There are several ways in which you could fix this.

The number one suggestion that I would suggest is plug the USB receiver into a different port. (while the computer is off). Keep trying all your ports and make sure you press the connection button after each attempt.

If all is wrong and all USB ports seem not to work but you're signals are still strong...

Try this

*I would highly recommend trying to get into your windows desktop with the malfunctioning keyboard and the functioning mouse along with an extra functioning keyboard plugged in.

Turn off your computer and plug in an extra keyboard that will 100% work (i.e a cord keyboard)
Turn on your computer and follow this directory: Start -> Run -> devmgmt.msc
A device manager should pop up.
Now expand the 'Keyboards' section
The device should read the EXTRA keyboard name but that is not what you want.
What you want is for it to say 'Microsoft USB Dual Receiver Wireless Keyboard (intelliType Pro)' this is the name of your malfunctioning keyboard which is probably not there.

If that name is not there expand the 'Human Interface Devices' section
Scan the names and look for the icon that has a 'Yellow Exclamation Mark' meaning an error or a problem. Right click it and select properties.

Under device status, it should say 'this device is not working properly because its incomplete' or something along those lines. This generally means that while windows was trying to install the driver for your keyboard, a problem occured in the process of it.

To fix this right click the errored device and select uninstall.
Once uninstalled, select the action tab at the top and select 'scan for hardware changes'

If you have windows XP there should be several icon pop ups on the bottom right of your screen saying a device has been successfully installed etc. Which means only one thing. Your keyboard now works.

As extra... you can see your device now installed by expanding the keyboards section or opening microsoft keybaord intellitype and selecting hardware.

BTW my operating system is windows XP 2000

Hey there, my a4 Tech mouse stops and starts, with new baterries! It works fine but then it just konks out! for no reason that I can see! the keyboard works fine, but the mosuye works for 5 seconds, then...

You could try to re-sync it to the receiver and also look at anything that might block the receiver both physically like cords or books or electronically like too close to another electronic device. The phone cord to my multi-line phone actually interferes with the signal for my keyboard.

The light on the transmitter is no longer on, but if I put it close to my keyboard and mouse, they work fine..Is there a battery in the transmitter that controls the signal strength??

The light doesn't need to be on to work. the lights on the transmitter indecate if the number or cap lock is on or if the mouse or keyboard batteries are low.

Signal strength has fallen from excellent to very low. strength on laptop and desktop pc remain excellent. Sounds like a NB100 glitch, but what?

As i understand your concern that on your laptop and desktop pc you are getting excellent signals so it might be possible that your third device required to upgrade the drivers for that. Because sometime it happened that the device driver not working properly.

Microsoft Laser Mouse 5000 stopped working altogether

Make sure the batteries are good and then follow these instructions.

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud

Keyboard not working

To connect the keyboard or mouse to the computer, you must connect the wireless device through the USB port and get it to hold a good connection. You do not have to install any devices to use these products, they automatically work when you plug them in. When it says that the device is recognized, you are ready to use it! If you have a desktop, you can also plug the wireless device to the mouse port. The keyboard and mouse work properly up to 5' away from the connected wireless device. If you can get the wireless device to work properly, you should have no troubles with the product.

The part that goes into the USB port is the mouse receiver. If it has a button on it, press it and then tuen your mouse over and press the button on the bottom of your mouse. This is the reset/connect button.
Hope this is of some help. Bud

Do you have any other wireless devices nearby? There could be interference between the different devices. Or as r_generato says, you might want to replace the batteries with new ones since reception distance is directly proportional to battery strength. Also, if you use rechargable batteries, they work at a slightly lower voltage and non-rechargeable, alkaline batteries will probably get better performance.
