    • While holding the switch in the open position, lift out the battery.

    • If you plan to work on any internal laptop components, press and hold the power button for 5 seconds. This will dissipate any residual charge on the motherboard to prevent electrical shock when you begin to handle it.

    • Using a Phillips head screwdriver, remove the screws shown in the image. They all have the letter "P" next to them.

    • Carefully unplug the connections shown.

    • Don't forget the display cable. It is slightly to the right of the Dell logo at the top.

    • Also, the wireless cables on the right side may prevent moving the upper case out of the way.

    • Once the screws have been removed and the connections unplugged, use the plastic opening tool to gently separate the panel from the lower case.

    It probably better to leave the small blue battery to the left plugged in for the Bios Chip. Just lift the batter out of its holder and move it out of the way as the cover is moved. If unplugged the computed will ask you to run setup when you start the computer.

    • Remove the plastic case by gently bending back towards the screen. You can bend the screen all the way back if that helps.

    • For the motherboard the optical drive will be removed already. However for the lower case it is not necessary that it be taken out.

    • If you are having trouble removing the upper plastic case (and LCD) from the lower case, there may still be a wire connected to the Wi-Fi adapter. Turn the laptop over, open the Wi-Fi module access panel and remove the + and - leads for the Wi-Fi antenna.

    Need to add a caution when rotating the cover to be careful with the hinge post on the right side. you can snag the GPU heat pipe as you rotate the cover. So watch the maneuver.

You can tell which if the system has 1 or 2 cooling fans. Systems with discreet graphics will have a second cooling fan in upper right as shown in the picture. Integrated graphics will not have the same video card as shown nor a second cooling fan. The motherboards are pinned out to support the fans as well as the base which has a open air flow vent.
