Click the Windows 'Start' button
Click Control Panel
Click Mouse
Check that some "action" is associated with the SECOND (usually the RIGHT) mouse-button.

Try the mouse on some other computer, to see if the button works on that computer.

there will be a button on your mouse. Press it to sync the settings with your laptop and it should start to work.

or else

click start
right click my computer

hardware
device manager
?mouse and keyboard
scan for hardware changes

You replaced the batteries. Okay. Did you install drivers for the mouse from a CD? Are you using Windows XP? Do you notice any change if you use the mouse on a darker surface as opposed to lighter surface? If the computer installed the drivers for you, then you might want to delete them in Device Manager (might be called something like HID-Compliant Mice. Single click on that entry, press the delete key. You might have to reboot your PC after that. From there you might have to unplug, then plug in the mouse again and you should notice the driver reinstalling. Give it a second and all should be good.

*Access the Device Manager by right-clicking on My Computer, select Properties, go to the Hardware tab and select Device Manager.
