Shutting Down Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Owner's Manual.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not
covered by your warranty.
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.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
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.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
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.
