Dell HR675 owner manual Troubleshooting the Keyboard or Mouse, 135

Action

1Check the system and power connections to the monitor.

2Determine whether the system has an expansion card with a video output connector.

In this system configuration, the monitor cable should normally be connected to the connector on the expansion card, not to the system’s integrated video connector.

To verify that the monitor is connected to the correct video connector, turn off the system and wait for 1 minute, then connect the monitor to the other video connector and turn the system on again.

3Run the appropriate online diagnostic test (see "Using Dell PowerEdge Diagnostics" on page 163).

If the tests run successfully, the problem is not related to video hardware. If the tests fail, see "Getting Help" on page 175.
