Troubleshooting Solving Hardware Problems • Ensure the keyboard is connected to the keyboard connector rather than the mouse connector on the rear panel of the workstation. • Ensure you are using a PS2 keyboard rather than a USB keyboard. • Replace the keyboard with a known working unit to ensure the keyboard itself is not defective. Monitor Doesn't Work If the display is blank, refer to "Display is Blank" on page 31. If the display works properly during the Power-on-Self-Test (POST), but goes blank when Windows starts, the display settings in the operating system may not be compatible with your monitor. To correct this, restart your workstation in VGA mode: • Windows 2000 or Windows XP: When prompted, press F8 and start the workstation in VGA mode. After the workstation is up and running, change the display settings in the control panel (Start > Settings > Control Panel). Refer to your operating system documentation for more information. Mouse Doesn't Work If your mouse does not work as expected: • Ensure that the mouse cable is firmly connected. See "Connect the Components" on page 11. • Ensure that the mouse is connected to the mouse connector rather than the keyboard connector on the rear panel of your workstation. • Ensure you are using the correct driver. The driver for the HP enhanced mouse is provided with all Windows preloaded systems as well as on the HP Workstation Recovery CD-ROMs. However, drivers are constantly being updated. You can download the latest driver from the HP web site (www.hp.com/go/workstationsupport). • Clean the mouse ball with a dry, lint-free cloth if the cursor moves sporadically. • Replace the mouse with a known working unit to ensure the mouse itself is not defective. 32 Chapter 2
