Troubleshooting Your Workstation Case 2: Monitor Is Blank, MaxiLife Is OK HP x2100 INFO SERVICE NOTE Case 2: Monitor Is Blank, MaxiLife Is OK When the power button is pressed, the workstation appears to boot (sound from the hard disk drive and fan, and status LED is green), but the monitor is blank. • Hard disk drive and fan can be heard. • Status LED is GREEN. • MaxiLife status panel displays system booting. Before removing the cover, always switch off the display and workstation. Disconnect the power cord and any accessory cables. When checks have been completed, close the workstation and reconnect the power cord and accessory cables. Verify that the workstation boots correctly. Symptom... Power indicator light and hard disk activity light work but the screen remains blank. : Check that... The display is switched ON (LED is on). The monitor's power cord is correctly connected. The monitor's power outlet is working. The monitor's brightness and contrast settings are correct. The monitor itself is not faulty. The video cable pins are not damaged. You may need to update the Basic Input Output System (BIOS). How... Refer to the monitor manual for an explanation of the LEDs. Ensure the power cord is plugged into a grounded power outlet and into the monitor. Plug a light into the grounded power outlet and check that it comes on. Refer to the monitor manual if necessary. 1. Replace the monitor by a known working monitor from the same model of workstation. 2. If the monitor starts, contact HP Support or your authorized dealer. The monitor may need to be replaced. 1. Switch off and unplug the monitor. 2. Disconnect the video cable and straighten any bent pins. 3. Reconnect the video cable. 4.
