You have just completed installing more memory in a laptop computer. You boot the computer and log on. When you try to use the trackpad to open the Start menu, the mouse pointer does not move.
What should you do?
1. Remove your ESD wrist strap.
2. >>Reboot the computer and enter CMOS to change the input device.
3. Verify that a mouse is not connected to the PS/2 port.
4. Verify that the Fn key is not pressed.
Explanation : You should remove your ESD wrist strap. The trackpad works using static electricity. Therefore, if you are wearing an ESD wrist strap, it will not be able to sense electricity in your fingertips. A similar problem can occur if a user has long fingernails.
The Fn key does not affect the trackpad. It is used to toggle the functionality of certain keys.
You cannot change the input device in CMOS. The computer will use the trackpad as its input device automatically.
When you attach a mouse to a PS/2 or USB slot, the trackpad will still function. Therefore, verifying that a mouse is not connected to the PS/2 port will not solve the problem.
