PCNs give customers advanced notice of changes to their product, such as an updated BIOS version that they may need to qualify prior to the change taking place. The latest PCNs are located at: http://www.hp.com/go/workstationsupport. Helpful hints If you encounter a problem with the workstation, monitor, or software, the following general suggestions might help you isolate and focus on the problem before taking further action. At startup ● ● ● Verify that the workstation and monitor are plugged into a working electrical outlet. Remove all optical discs and USB drive keys from the drives before powering on the workstation. Verify that the workstation is turned on and the power light is on. If you have installed an operating system other than the factory-installed operating system, check to be sure that it is supported on your system by visiting http://www.hp.com/go/quickspecs. Verify that the monitor is turned on and the green monitor light is on. Turn up the brightness and contrast controls of the monitor if the monitor is dim. If the workstation has multiple video sources and only a single monitor, the monitor must be connected to the source selected as the primary VGA adapter. During startup, the other monitor connectors are disabled; if the monitor is connected to one of these ports, it will not function after Power-on Self Test (POST). You can select the default VGA source in Computer Setup (F10). 80 Chapter 4 Diagnostics and troubleshooting
