In this guide, you will be shown how to replace a battery for a Dell XPS 16 9640 laptop computer. This repair may be needed if your computer is not turning on or has a reduced battery life.

While this repair is easy, it does require steady hands to avoid damaging important components.

Before you begin the repair, unplug and power off your laptop. For your safety, discharge the battery below 25% before disassembling your device. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

The first step is to locate the screws holding the back cover in place.
The red circles in the image highlights what the the screws look like, and where they are.
Use the torx screwdriver to remove each 3.0mm torx screw.
You will know when this step is fully complete when you have unscrewed a total of 8 3.0mm torex screws.
Be sure to place the screws together and in a safe location.

Now, pop open the back cover. The cover is attached to the body of the computer by several clips located around the perimeter of the computer, which is shown in the picture by the red square.
You should be able to use only your fingers to lift the lid, but in the case where you are unable to remove it, I recommend using a plastic pry tool to gently pry it open. This is done by wedging the tool under the cover and slowly pushing down until the clip comes undone. Do this to each clip until it comes off.

Be careful not to accidentally damage any components during this step and the next. This is avoided by not touching anything and being aware of where you use your tool.
