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.
NOTE: 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.
NOTE: 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.
