Take the keyboard and its receiver (&driver if necessary) to another machine. If it works there then it is a driver issue with your computer. If also dead then time to go shopping.

Hi Mark...is it only one of the [SHIFT] keys that is non-operational? If so, please see the instructions I've posted for a similar problem:Number 1 appears to be stuck

It's quite likely this solution will fix your problem as well, but if not, please let me know and we can try a few other solutions.

Do a Hard Reset method to clear the keyboard and mouse settings and reconnect it back to your computer:

• Remove the batteries from the keyboard
• Press the Connect button on the receiver for 10 seconds.
• Press the Connect button on the mouse.
(You might need a pencil tip or other small tip to press the connect button.)
• Insert the batteries back into the keyboard.
• Press the Connect button on the receiver.
• Press the Connect button on the keyboard.
Hope this helps

Please rate this solution, thanks!

try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.
dust causes static which causes lots of problems with a computer and its parts
scroll to the bottom toolbar (bottom of screen) right click you can select task manager applications also processes you will see whats running on your computer you might have a virus also select users you will see who is using your computer
you might have to many programs loading at start up or you might have a virus run your antivirus program then
click start control panel keyboard hardware then properties you should see driver details,you will have options to update driver,roll back driver,uninstall
make sure you have the driver for the keyboard before uninstalling the driver
make sure the lead is good and has a secure connection diconnect the keyboard then reconnect it then reinstall the driver
try uninstalling a few unnecessary programs then click start run type cmd then type chkdsk/r/f which will scan for and attempt to fix any bad sectors and automatically fix any corrupt files on your hard drive then defragment your hard drive
as for the mouse
make sure the battery is good (has full charge)also you might test the usb device for the mouse is inserted correctly into the usb port (if applicable)

i've experienced the exact same problem :
mouse working ok, but i was unable to get any response from the keyboard.

i tried to update the drivers, i tried reinstalling the drivers on a clean boot, nothing would do. but then i tried to use my computer with a classic usb keyboard, which caused xp to detect both keyboards on startup, without managing to install either of them.

so that's how i found out my problem, which i hope is also yours, was that the proper driver for usb keyboards is not signed. so somehow xp would refuse to use it. forcing a manual install of that unsigned driver on both keyboards made the both of them finally work.

so if you have not tried that yet, i suggest you to reinstall your keyboard driver
without letting windows select the driver automatically (forgive any clumsy translation, i'm running a french version) :

1. find your keyboard in the device list (configuration panel > system > hardware > device list)
2. right click on it, go to properties, and choose reinstall driver
3. the installation wizard is then launched, tell him you wish to specify the location of your driver
4. in the second step of the wizard, tell him not to search for the driver, you'll select it manually from the list
5. in the list that appears next, select Human Interface Devices (my driver was in the HID section)
6. among the drivers in that section (there were 2 in mine), one of them is not signed, select that one and install it.

that's how i got my keyboard to work, hope this may be helpful to you in any way

look just after the F12 key, there should be an insert key on that model keyboard, may be hard to spot or in a different colour writing.
If you still cant find it, use the on screen keyboard's insert key

1. Click on Start and click on "Run"

2. Type osk and click OK.

3. You will see the On Screen Keyboard (OSK)
