Windows Label
This Microsoft® Windows label provides the product key for your copy of Windows. You will need this information if you ever reinstall Windows.
USB Connectors
Although any USB device can be attached to either the front- or back-panel USB connectors, Dell recommends using the front-panel USB connectors for devices
that you frequently connect and disconnect, such as USB digital cameras and gaming controllers. Use the back-panel USB connectors for devices that you
rarely connect and disconnect, such as USB printers, scanners, mouse, and keyboards.
Headphone Jack
Use the headphone jack to attach headphones and most speakers for listening to all sounds in your computer including your CD player and system sounds
such as beeps.
Service Tag
This label lists your computer's service tag and your Express Service Code (if applicable). If you call Dell technical support, use your Express Service Code to
route the call directly to the correct support personnel. The Dell technical support staff will ask for your service tag.
