Turning Off Your Computer
1. Shut down the operating system:
a. Save and close any open files, exit any open programs, click Start® Shut Down.
b. Select Shut down® OK.
The computer turns off after the operating system shutdown process finishes.
2. 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 4 seconds.
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: Some of the parts described in this chapter may be replaceable by a certified service technician only and are not customer-
replaceable.
NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.
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: 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 pull-tab, 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.
1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
2. Turn off your computer (see Turning Off Your Computer).
3. Disconnect any telephone or network cables from the computer.
4. Disconnect your computer and all attached devices from their electrical outlets.
5. Remove the battery (see Replacing the Battery).
6. Press the power button to ground the system board.
Hard Drive

1. Follow the procedures in Before You Begin.
2. Turn the computer upside-down, and remove the two screws that secure the hard drive carrier to the chassis.
3. Slide the hard drive carrier out of the computer.
NOTICE: To prevent damage to the computer, perform the following steps before you begin working inside the computer.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall connector.
NOTICE: To prevent damage to the system board, remove the main battery before you service the computer.
CAUTION: If you remove the hard drive from the computer when the drive is hot, do not touch the metal housing of the hard drive.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

Memory
You can increase your computer memory by installing memory modules on the system board. See Specifications for information on the memory supported by
your computer. Install only memory modules that are intended for your computer.
The computer has two memory module connectors labeled "DIMM A" and "DIMM B." DIMM A is located on top of the system board (under the keyboard), and
DIMM B is located on the bottom of the system board under the memory module cover. If only one memory module is installed, it must be installed in DIMM A,
as configured from the factory. If you did not order additional memory, DIMM B is empty. Generally, if you add memory, you add by installing a memory module
in DIMM B. If you are upgrading memory, you may need to remove and install memory modules in both DIMM A and DIMM B, depending on the extent of the
upgrade.
To install a memory module in DIMM A:
1. Follow the procedures in Before You Begin.
2. Remove the hinge cover (see Hinge Cover).
3. Remove the keyboard (see Keyboard).
4. Ground yourself by touching one of the metal connectors on the back of the computer.
5. If you are replacing a memory module, remove the existing module:
a. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.
b. Remove the module from the connector.
