Turning Off Your Computer
1. Shut down the operating system:
a. Save and close any open files, exit any open programs, click the Start button, and then click Turn Off Computer.
b. In the Turn off computer window, click Turn off.
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, turn them off now. 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.
1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
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.i
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as
authorized in Dell's product documentation, or as directed by Dell's online or telephone service and support team. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
NOTICE: 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: 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.
2. Turn off your computer.
3. If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.
4. Disconnect any telephone or telecommunication lines from the computer.
5. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
6. Remove any installed PC Cards from the PC Card slot.
7. Close the display and turn the computer upside down on a flat work surface.
8. Slide and hold the battery-bay latch release on the bottom of the computer, and then remove the battery from the bay.
9. Remove any installed modules, including a second battery, if installed.
10. Remove the hard drive.
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 slots, DIMM A and DIMM B. DIMM A (located under the keyboard) holds the basic memory module as configured from the factory.
If you did not order additional memory, DIMM B (located on the bottom of the computer under the options door) will be empty. Generally, if you are adding
memory, you will install a memory module in DIMM B. If you are upgrading memory, you may need to install memory in DIMM A and B depending on the extent
of the upgrade.
Memory Module DIMM B

NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.
NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.
NOTICE: To avoid damaging the system board, you must remove the main battery before you service the computer.
