Calling technical support
At times you might encounter an issue that requires technical support. When you call technical support:
Have the computer readily accessible.
Write down the computer serial numbers, product numbers, model names, and model numbers
and have them in front of you.
Note any applicable error messages.
Note any add-on options.
Note the operating system.
Note any third-party hardware or software.
Note the details of any blinking LEDs on the front of the computer.
Note the applications you were using when you encountered the problem.
When calling in for service or support, you might be asked for the Product Number (example:
PS988AV) of the computer. If the computer has a Product Number, it is generally located next to the
10- or 12-digit Serial Number of the computer.
On most models, the serial number and product number labels can be found on the top panel
or side of the computer and at the rear of the computer.
