## Preparing to Work Inside the Computer

| CAUTION: Before working inside your computer, read "Safety and EMC Instructions: Portable Computers" in your System Information Guide.

| 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: To avoid damaging the computer, perform the following steps before you begin working inside the computer.

1. Make sure that the work surface is clean to prevent scratching the computer cover.
2. Save any work in progress and close all open programs.
3. Turn off the computer and all attached devices.

| NOTE: Make sure the computer is turned off and not in suspend-to-disk or hibernate mode. If you cannot shut down the computer using the computer operating system, press and hold the power button for 4 seconds.

1. Make sure the computer is undocked.
2. Disconnect the computer from the electrical outlet.
3. To avoid possible damage to the system board, wait 10 to 20 seconds and then disconnect any attached devices.
4. Disconnect all other external cables from the computer.
5. Remove any installed PC Cards or plastic blanks from the PC Card slot.
6. Close the display and turn the computer upside down on a flat work surface.

| NOTICE: To avoid damaging the system board, you must remove the main battery and secondary battery (if present) before you service the computer.

1. Remove the primary battery from the battery bay and the secondary battery from the module bay, if a secondary battery is in use.
2. Remove any installed device in the module bay.
3. To dissipate any static electricity while you work, use a wrist grounding strap or periodically touch an unpainted metal surface.
4. Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by it edges or by its metal mounting bracket. Hold a component such as a microprocessor by its edges, not by its pins.
