•If your computer gets wet or is damaged, follow the procedures described in "Solving Problems" in your User’s Guide. If, after following these procedures, you confirm that your computer is not operating properly, contact Dell (see "Getting Help" in your User’s Guide for the appropriate contact information).

SAFETY: Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard use may result in injury.

CAUTION: Viewing the display or external monitor screen for extended periods of time may result in eye strain.

For comfort and efficiency, observe the ergonomic guidelines in the "Appendix" of your online User’s Guide when setting up and using your computer.

This portable computer is not designed for continuous operation as office equipment. For extended use in an office, it is recommended that you connect an external keyboard.

SAFETY: When Working Inside Your Computer

Before removing or installing memory modules, Mini PCI cards, or modems, perform the following steps in the sequence indicated.

NOTICE: The only time you should ever access the inside of your computer is when you are installing memory modules or a Mini PCI card, modem, Bluetooth™ card, or reserve battery.

NOTICE: Wait 5 seconds after turning off the computer before disconnecting a device or removing a memory module, Mini PCI card, modem, Bluetooth card, or reserve battery to help prevent possible damage to the system board.

1Shut down your computer and turn off any attached devices.

2Disconnect your computer and devices from electrical outlets to reduce the potential for personal injury or shock. Also, disconnect any telephone or telecommunication lines from the computer.

3Remove the main battery from the battery bay and, if necessary, the second battery from the module bay.

4Ground yourself by touching any unpainted metal surface on the back of the computer.

5While you work, periodically touch the unpainted metal surface to dissipate any static electricity that might harm internal components.

SAFETY: Protecting Against Electrostatic Discharge

Static electricity can harm electronic components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as a memory module. You can do so by touching any unpainted metal surface on the back of the computer.

As you continue to work inside the computer, periodically touch any unpainted metal surface on the back of the computer to remove any static charge your body may have accumulated.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

•When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

•When transporting a sensitive component, first place it in an antistatic container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
