Shutting Down Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.
1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
2. Shut down the computer.
3. Ensure that the computer and any attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, press and hold the power button for 4 seconds.
4. If the computer is connected to a media base (docked), undock it. See the documentation that came with your media base for instructions.
5. Disconnect any telephone or telecommunication lines from the computer.
6. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a microprocessor by its edges, not by its pins.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with
locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and
aligned.
