Preventing static electricity discharge

    The components inside your computer are extremely sensitive to static electricity, also known as electrostatic discharge (ESD).

    Caution

    ESD can permanently damage electrostatic discharge sensitive components in the computer. Prevent ESD damage by following ESD guidelines every time you open the computer case.

      Before opening the computer case, follow these guidelines:

    Turn off the computer power.
    Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal part of the computer.

      Warning

      To prevent risk of electric shock, do not insert any object into the vent holes of the power supply.

      Touch a bare metal surface on the back of the computer.
      Unplug the power and modem cables.

        Before working with computer components, follow these guidelines:

      Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam.
      Remove components from their antistatic bags only when you are ready to use them. Do not lay components on the outside of antistatic bags because only the inside of the bags provide electrostatic protection.
      Always hold expansion cards by their edges or their metal mounting brackets. Avoid touching the edge connectors and components on the cards. Never slide expansion cards or components over any surface.

        Warning

        To avoid exposure to dangerous electrical voltages and moving parts, turn off your computer and unplug the power cord before opening the case.

        Replacing the system battery

          If the computer clock does not keep time or the settings in the BIOS Setup utility are not saved when you turn off the computer, replace the system battery.

          Replace the battery with the same or an equivalent of the original battery that was in the computer.

          Caution

          Danger of explosion if battery is incorrectly replaced.

          Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

          To replace the battery:

            1. Enter the BIOS Setup utility, according to the instructions in "Using the BIOS Setup utility".

            2. Write down all the values in the menus and submenus, then exit from the utility.

            3. Following the static electricity precautions, "Preventing static electricity discharge", open the computer case using the instructions in your user's guide.

            4. Press the battery retention clip and lift the battery out of the socket.

            1. With the positive (+) side of the battery towards the positive (+) label on the outside edge of the system board, press the new battery into the socket until it snaps into place.

            2. Close the computer case.

            3. Plug in the power cable and peripherals.

            4. Turn on the computer.

            5. Enter the BIOS Setup utility, according to the instructions in "Using the BIOS Setup utility".

            6. In the BIOS Setup utility, restore any settings that you wrote down in Step 2.

            7. Save and exit the BIOS Setup utility.

          Using the BIOS Setup utility

            The BIOS Setup utility is used to determine the basic settings for your computer. These settings include basic system hardware configuration, system resource settings, and password security. These settings are stored and saved even when the power is off.

            Caution

            The options in the BIOS Setup utility have been set at the factory for optimal performance. Changes to these settings will affect the performance of the computer.

            Before changing any settings, write them down in case you need to restore them later.

            To enter the BIOS:

              1. Restart the computer. Your computer displays the message, "To change system settings press the F1 key."

              2. Press F1. The main menu of the BIOS Setup utility opens.

              The following illustration shows the main menu screen of a typical BIOS Setup utility. Your system BIOS Setup utility may vary slightly from the illustration below.
