The Dell Cordless iTouch keypad on my husband's computer has somehow disconntected. I replaced the batteries but it still won't work. I've restarted the computer and it still won't work. There doesn't seem to be a connect button on the keypad back. How can I get it to reconnect?

There is not of troubleshooting you can do with this .... Only two steps

Check the cable from the reciver to the back of the computer.
Check the battery on the keyboard and mouse.

On the right hand side top of the keyboard there should be a connect button. press the keyboard and receiver button to together for 5 sec.
Same button you will find on the back of mouse, try the same it will sink the mouse too.

If still not working, buy a new one.
Kindly rate the answer

Good Luck & Thanks

If you can synchronize the mouse to the receiver but not the keyboard, or vice versa, please use the following steps to synchronize all the devices together.
1. Remove the batteries from the keyboard.
2. Make sure you have the mouse synchronized. To do this, press the connect button on the receiver, then press the connect button on the mouse.
3. Open the iTouch Configuration Panel by double clicking the iTouch icon in the Systray.
4. Click the Cordless tab.
5. Click the Connect button in the Control Panel. A dialog box will appear instructing you to press the connect button. Before you do, you should re-insert the batteries.
6. After inserting the batteries, press the connect button on the keyboard.
7. Verify both devices function correctly.

The button is a pin hole button (you may need a pencil). It should be located on the right hand edge , and not on the bottom side like on other wireless keyboard not on the top). His location is on the side in correspondence of the space between the number pad and the indicator panel
