Troubleshooting Your Computer Troubleshooting Techniques Keyboard and Pointing Device Problems If the pointer is difficult to control • Adjust the pointer controls: click Start, Settings, Control Panel, then double-click Mouse. If the pointing stick doesn't work • Don't move the pointing stick while the computer is rebooting or resuming from Standby mode. If this happens, try the following: • Press a key on the keyboard to restore normal operation. • Suspend and resume operation using the blue sleep button. • If an external mouse is connected, the pointing stick is normally disabled. You can change this setting with the BIOS Setup utility-see "Using the BIOS Setup Utility" on page 86. • Restart the computer: click Start, Shut Down, Restart. If the scroll button doesn't scroll in some applications • For Windows 2000, some applications do not support the default type of scrolling used by the scroll button. You can use Mouse in Control Panel to make the scroll button work like a standard middle mouse button in all applications. If a PS/2 scroll mouse doesn't work • The mouse must automatically replace the pointing stick for the mouse's scroll feature to work. In the BIOS Setup utility, make sure the PS/2 Pointing Devices option in the System Devices menu is set to Auto. See "To run the BIOS Setup utility" on page 86. • Suspend or shut down the computer before you attach the scroll mouse, so that it will be detected properly. • Test the keyboard and pointing stick with the e-DiagTools diagnostics-see "Testing the Hardware" on page 162. If the embedded numeric keypad doesn't work • To type numbers, make sure Num Lock is on. • Make sure the embedded Keypad Lock (Fn+F8) is on-or that you press and hold the Fn key to temporarily access the embedded keypad. 148 Corporate Evaluator's Guide
