Troubleshooting the Video Subsystem

1Check the system and power connections to the monitor.

2Check the video interface cabling from the system to the monitor.

3Run the appropriate Embedded System diagnostic test. See "Running the Embedded System Diagnostics" on page 140.

If the tests run successfully, the problem is not related to video hardware. If the tests fail, see "Getting Help" on page 149.

Troubleshooting a USB Device

Use the following steps to troubleshoot a USB keyboard and/or mouse. For other USB devices, go to step 5.

1Disconnect the keyboard and mouse cables from the system briefly and reconnect them.

2Connect the keyboard/mouse to the USB port(s) on the opposite side of the system.

3If the problem is resolved, restart the system, enter the System Setup program, and check if the nonfunctioning USB ports are enabled.

4Replace the keyboard/mouse with another working keyboard/mouse. If the problem is resolved, replace the faulty keyboard/mouse.

If the problem is not resolved, proceed to the next step to begin troubleshooting the other USB devices attached to the system.

5Turn off all attached USB devices and disconnect them from the system.

6Restart the system and, if your keyboard is functioning, enter the system setup program. Verify that all USB ports are enabled. See "Integrated Devices Screen" on page 45.

If your keyboard is not functioning, you can also use remote access. If the system is not accessible, see "System Board Jumpers" on page 143 for instructions on setting the NVRAM_CLR jumper inside your system and restoring the BIOS to the default settings.
