Diagnosis guidelines

If you encounter a problem with the computer, monitor, or software, the following sections provide a list
of general suggestions that help you isolate and focus on the problem before taking further action.

Diagnosis at startup

Verify that the computer and monitor are plugged into a working electrical outlet.
Remove all diskettes, CDs, or USB drive keys from your system before turning it on.
Verify that the computer is turned on and the green 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. Note that not all monitors are
equipped with LED lights to indicate their functionality.
Turn up the brightness and contrast controls of the monitor if the monitor is dim.
If the computer has multiple video sources and only a single monitor, the monitor must be
connected to the primary display 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 source in Computer Setup (F10).
