HP Z1 Maintenance And Service Guide

Diagnosis guidelines
If you encounter a problem with the computer 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 external monitor (if connected) are plugged into a functional AC
power outlet.
●
Remove all CDs or USB drive keys from your system before turning it on.
●
Verify that the computer is turned on and the power light is blue (normal operation) and not red
(error state).
●
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.
Diagnosis during operation
●
Look for blinking LEDs on the side of the computer. The blinking lights are error codes that will
help you diagnose the problem. Refer to the
Diagnostic LED and audible (beep) codes
on page 83 section of this document for information on interpreting diagnostic lights and
audible codes.
●
Check all cables for loose or incorrect connections.
●
Wake the computer by pressing any key on the keyboard or the power button. If the system
remains in suspend mode, shut down the system by pressing and holding the power button for at
least four seconds, and then press the power button again to restart the system. If the system does
not shut down, unplug the power cord, wait a few seconds, and then plug it in again. If it does
not restart, press the power button to start the computer.
●
Reconfigure the computer after installing a non–plug and play expansion board or other option.
●
Be sure that all required device drivers have been installed. For example, if you have connected a
printer, you must install a printer driver.
●
If you are working on a network, plug another computer with a different cable into the network
connection. There might be a problem with the network plug or cable.
●
If you recently added new hardware, remove it and see if the computer functions properly.
●
If you recently installed new software, uninstall it and see if the computer functions properly.
●
Upgrade the BIOS. A new release of the BIOS might have been released that supports new
features or fixes your problem.
●
Press the Caps Lock key. If the Caps Lock LED toggles on or off, the keyboard is operating
correctly.
