Locating ID labels
To assist in troubleshooting, product, serial, and authentication numbers are available on each computer.
●All workstations have a serial number (unique for each workstation) and product number. Have these numbers available when you contact support.
●The Certificate of Authentication (COA) is used only for systems preinstalled with Windows.
●A service label shows the build ID and Feature Byte strings, which are needed for system board replacement.
In general (tower and desktop configuration), these labels can be found in the top, rear or bottom of the chassis (your workstation might look different).
