Labels
The labels affixed to the computer provide information you may need when you troubleshoot system
problems or travel internationally with the computer.
●
Service label—Provides important information to identify your computer. When contacting support,
you will probably be asked for the serial number, and possibly for the product number or the model
number. Locate these numbers before you contact support.
Your service label will resemble one of the examples shown below. Refer to the illustration that most
closely matches the service label on your computer.
Component
(1) Product name
(2) Serial number
(3) Product number
(4) Warranty period
(5) Model number (select models only)
●
Microsoft® Certificate of Authenticity label (select models only prior to Windows 8)—Contains the
Windows Product Key. You may need the Product Key to update or troubleshoot the operating system.
HP platforms with Windows 8 or Windows 8.x preinstalled do not have the physical label. Instead a
Digital Product Key is electronically installed.
NOTE: The Digital Product Key is automatically recognized and activated by Microsoft operating
systems when a Windows 8 or Windows 8.x operating system is reinstalled using HP-approved recovery
methods.
●
Regulatory label(s)—Provide(s) regulatory information about the computer.
●
Wireless certification label(s)—Provide(s) information about optional wireless devices and the approval
