HP Z238 User Manual

Before you call for technical support
WARNING! When the workstation is plugged into an AC power source, voltage is always applied to the
system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet and allow the internal system components to cool before you
touch them.
If you are having problems with the workstation, try the appropriate solutions as described in the previous
sections and summarized below to try to isolate the exact problem before calling for technical support.
●
Check the power LED on the front of the workstation to see if it is ashing and listen for a series of
beeps emanating from the workstation. The
ashing lights and/or beeps are error codes that will help
you diagnose the problem. Refer to the Maintenance and Service Guide (English only) for details.
●
If the screen is blank, plug the monitor into a dierent video port on the workstation if one is available.
Or, replace the monitor with a monitor that you know is functioning properly.
●
If you are working on a network:
◦
Use a dierent network cable to connect your workstation to the network.
◦
Connect a dierent workstation with a dierent cable to the network.
If your problem is not resolved, the network jack on your workstation or the network wall jack might be
faulty.
●
If you recently added new hardware, remove the hardware.
●
If you recently installed new software, uninstall the software.
●
Comprehensive online technical support is also available at http://www.hp.com/support.
●
If the workstation will turn on but will not boot into the operating system, you may run the “pre-boot”
diagnostics utility, HP PC Hardware Diagnostics. Refer to Setting up, backing up, restoring, and
recovering Windows 10 on page 15 for more information.
●
If the workstation will boot into the operating system, there are two possible tools that provide self-
solve diagnostics and online chat features (if internet access is also available).
◦
If you have HP Support Assistant, you may access it from the Start screen by clicking the HP
Support Assistant app, clicking My computer, and then clicking Diagnostics.
◦
If you do not have HP Support Assistant installed, you may access HP Instant Support Professional
Edition at http://www.hp.com/go/ispe.
You may also access the Business Support Center (BSC) at http://www.hp.com/go/bizsupport for the latest
online support information, software and drivers, for proactive notication, and access to a worldwide
community of peers and HP experts.

If it becomes necessary to call for technical assistance, be prepared to do the following to ensure that your
service call is handled properly:

●
Before calling, write down the product ID number, workstation and monitor serial numbers, and the
failure ID produced by running the diagnostics if applicable.
●
Spend time troubleshooting the problem with the service technician.
●
Remove any hardware that was recently added to your system.
