Check the control panel in two places:-

1. Pointers to see if you can use the existing driver, it maybe disabled there, or the settings need to be changed.

2. If it is disabled or unusable in pointers go to device manager and check if there is a yellow balloon next to the mouse, if so you have to replace the corrupt mouse driver software. global download gateway com

borrow another mouse go to control panel and change mouse settings if that doesnt work change mouse

is it a mouse settings prob, or mouse pad?

See if the mouse pad has been accidentally turned off. This can be done via the "Function" button on your Gateway laptop. To enable your mouse clicker again on your Gateway, head on over to the "Control Menu" in Windows and double-click on the "Control Panel" icon. Click on the "Mouse" option under the "Printers and Other Hardware" tab. In the next menu that pops up, click on the tab listed as "Device Settings." From this menu, you should be able to locate a listing for the mouse pad on your Gateway laptop. Click on this listing. From here, you should be able to enable the mouse again. Click "OK."

Head over to the official Gateway site online (see Resources). The above enabling of the mouse device under "Device Settings" may not have worked. Make your way to the "Software and Drivers" area of the site.

Check over your Gateway manual and find your specific serial number for your machine. Enter the number into the Gateway site when prompted and check to see if any driver updates exist for your mouse on your machine. If so, click to download the update, and then double-click the file on your computer to install it. Restart your Gateway laptop to have the changes take place. Your mouse should now work.
