Re: keyboard does not respond

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...

Re: keyboard does not respond

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

Hype optical mouse model no. HY-7005-WMA 2.4GHz isn't working properly, wont connect to any device. How do I get the adapter signal to read on my laptop?

So you're saying you've tried connecting to other devices to no avail?
Might be worth reading the direction carefully. Sometimes there's a reset/rescan button(small) on the mouse that needs to be engaged after everything is plugged in.

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!

Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it to Reset/Connect the mouse to the receiver and work properly.

Hope this helps you. 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.

GE Wireless mouse & keyboard

are both keyboard and mouse communicating with a single wireless devices, or each has it's own? sometime you need to sync the signal to the wireless device. but do this first... ask your sister if the mouse was working before she gave it to you, there is a possibility that the mouse is broken/no working. if it's an optical mouse, the mouse that has lights sensor, make sure it lights up...
