make and model

the wireless needs a battery that is good in all such keyboards
replace that. first.
did it ever work, ?or are you missing parts. (receiver, Blue tooth)

On the F-keys at the top row of your laptop's keyboard, you may see a bluetooth symbol, or a "wireless" tower or "waves" type symbol. If you jave this key, hold down the Fn key (lower left corner of the keyboard) and then try different actions with this "wireless" key. Click it and see if a menu comes up or a bluetooth symbol appears or if different lights around the laptop go on and off.

Are the batteries in correctly? If so, have you re-synced the devices?

no ther is not requirement of drivers , as go to blue tooth icon detect the device pair it and it will start working

If there is no light on the Bluetooth keyboard it means there is a problem with it.

If the Bluetooth keyboard is not responding try to do the following:

1. Change batteries
2. Go to control panel
3. Click Bluetooth Icon
4. Delete the Bluetooth Keyboard
5. Click on Add new wireless device
6. Press the pairing device on the keyboard
7. Bluetooth keyboard will be detected
8. Follow the onscreen instructions

Hope this helps, Tried it several times and it works perfectly

This isn't a fun solution - the best thing I've come across is to hit both reset buttons (on the computer, and on the keyboard) until both are flashing - pull up your bluetooth settings (from control panel (I've got mine shortcutted into my task bar)), then disconnect the keyboard, and search for a new item - after the computer finds a new keyboard, connect using a new pairing code.

While this might not be the best solution, it works for me, and I don't know of a better one, or quicker!

Deleted the mouse from bluetooth and then added again.found info at

Normally Dell keyboard require a wireless uSB plug in that connects to your computer and there is usually a small button on both the keyboard and the end of the connector. Press them both. Normally preplacing batteries causes the connection to be disrupted.
