About Add-on Card Installation
Your computer may have one or more open expansion slots, depending on the model configuration. An expansion slot
enables you to install add-on cards to expand the functionality of your system. The length of the add-on card should not
exceed 9.05 inches.
Add-on card configuration varies by model. Some models, such as Configure-to-Order (CTO) systems, may contain
preinstalled add-on cards.
Observe the proper safety precautions when you add cards to your Sony computer. See Before upgrading your
computer .
Installing an add-on card
1. Shut down your computer and turn off all peripheral devices, such as your printer.
2. Unplug your computer and any peripheral devices.
3. Remove the cover. See Removing the cover .
4. Locate an available expansion slot. Remove the slot cover's screw, and then remove the slot cover.
When removing a slot cover, be careful not to damage components on the system board or add-on
cards. You may need to temporarily remove add-on cards or other components that may be next to the slot cover
you want to remove.
