5.5 Calling Technical Support
At times you may encounter an issue that requires technical support. If after using the self-troubleshooting tools you still
cannot resolve your issue, note the following to help you locate the necessary information that will assist technical
support in resolving the situation.
• Be in front of your workstation when you call.
• Write down the workstation serial numbers, product numbers, model names, and model numbers before calling
and have them readily available.
• Note any applicable error messages.
• Note any add-on options.
• Note the operating system.
• Note any third-party hardware or software.
• Note any blinking LEDs on the front of the workstation.
• Note the applications you were using when you noted the issue.
• Be prepared to spend the time necessary troubleshooting the problem with the service technician.
NOTE: When calling in for service or support, you may be asked for the Product Number (example: PS988AV) of your
workstation. If your workstation has a Product Number, it is generally located next to the 10- or 12-digit Serial Number
of your workstation.
NOTE: Refer to section 2.6 “Serial Number and COA Label Location” for the location of the Serial Number label on
your workstation. In general, the Serial Number and Product Number label are located at the rear of the workstation.
