    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!

    Same problem - followed factory instructions to install drivers -> USB receiver plugged in -> Batteries put in (brand new)

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

    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

Help with my Logitech keyboard and mouse. I only have the keyboard and the mouse do i need anything else to get start?

You need the wireless signal receiver. Cordless mice and keyboards send out a signal that needs to be picked up by your computer. Most of these systems plug into your USB. Here's a photo: moondogwst75.jpg
It should look something like that device on the mid-right side of the photo. That device will pick up the signals. It plugs into your USB. I hope this helps!

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.

MS Notebook Wireless Mouse 6000

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.

Keyboard and touchpad

Have you attempted to use an external mouse? - USB - if so does that work?
if it does - Click on START - Control Pannel - Keyboard (& Mouse Respectively) - Click on the hardware Tab - Select the relevant Key Board, Click on Properties - this will give you a device status - if is is not working properly - click Trouble shoot & follow the onscreen instructions. - If is "Working Properly" click on Drivers - check your driver is updated, or roll back.

If you happend to be on a server and the keyboard and/or mouse have stopped responding - you will need to restart (The Server). Ensure that the Keyboard and mouse are on PS2 connections and not USB - the Severs do not like USB Connected Comms Devices. I have found if there are wireless mouse's &/or Keybourd's &/or any USB connected Mouse/Keyboard, they tend to somehow interfere with each other (i.e. the sever with one of the terminals) - only remedy I have ever managed to make work is restart.

Hope this helps
