Calling support
At times you might encounter an issue that requires support. Before you call 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 lights on the front of the computer (tower and desktop
configurations) or on the side of the computer (all-in-one configurations).
● 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: The serial number and product number labels can be found on a pull-out card at the side of
the display.
