Turning Off Your Computer
NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.
Save and close any open files and exit any open programs.
Click Start , click the arrow , and then click Shut Down.
The computer turns off after the operating system shutdown process finishes.
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 operating system, press and hold the power button for at
least 8 to 10 seconds until the computer turns off.
Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
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 processor by its edges, not by its pins.
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.
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 electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as a connector on the back of the computer).
NOTICE: To help prevent damage to the computer, perform the following steps before you begin working inside the computer.
Ensure that the work surface is flat and clean to prevent the computer
cover from being scratched.
NOTICE: To disconnect a network cable, first unplug the cable from your computer, and then unplug it from the network wall jack.
Disconnect any telephone or network cables from the computer.
Disconnect your computer and all attached devices from their electrical
outlets.
NOTICE: To help prevent damage to the system board, you must remove the battery from the battery bay before you service the computer.
NOTICE: To avoid damage to the computer, use only the battery designed for this particular Dell computer. Do not use batteries designed for other Dell computers.
Close the cover, turn the computer over, and place the computer on a
flat surface.
Slide and click the battery release latch.
Slide the battery out of the battery bay.

Remove the four M3 x 3-mm screws and slide the hard drive away from
the bay.
NOTICE: When the hard drive is not in the computer, store it in protective antistatic packaging (see "Protecting Against Electrostatic Discharge" in the Product Information Guide).
Replacing the Hard Drive
Remove the new drive from its packaging.
Save the original packaging for storing or shipping the hard drive.
NOTICE: Use firm and even pressure to slide the drive into place. If you use excessive force, you may damage the connector.
Slide the hard drive into the bay.
