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 online diagnostic test. See "Running the System Diagnostics" on page 125.

If the tests run successfully, the problem is not related to video hardware. If the tests fail, see "Getting Help" on page 133.

Troubleshooting a USB Device

Use the following steps to troubleshoot a USB keyboard /mouse. For other USB devices, go to step 4.

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 non functioning USB ports are enabled.

4Replace the keyboard/mouse with another working keyboard/mouse.

5If the problem is resolved, replace the faulty keyboard/mouse.

6If the problem is not resolved, proceed to the next step to begin troubleshooting the other USB devices attached to the system.

7Power down all attached USB devices and disconnect them from the system.

8Restart 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 44.

If your keyboard is not functioning, you can also use remote access. If the system is not accessible, see "Disabling a Forgotten Password" on page 132 for instructions on setting the NVRAM_CLR jumper inside your system and restoring the BIOS to the default settings.
