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 49. 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, refer to the section entitled "X server Parameters" on page 34. 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 13. • 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. You can download the latest driver from the HP web site (www.hp.com/workstations/support). • 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. Audio Doesn't Work The internal speaker is deactivated when you use the output line jack on the rear of the Workstation. If you have connected the multimedia keyboard's audio out (green) connector to this jack, you must connect speakers or headphones to the multimedia keyboard for audio output. If you don't have speakers or headphones, disconnect the keyboard's audio out connector from the back of the Workstation to enable the internal speaker. 50 Chapter 3
