Steps:

1. Remove the eight M2 5mm screws that secure the base cover using a Phillips #0 screwdriver.

2. Loosen the three captive screws that secure the base closer to the hinges.
3. Do not attempt to remove the three captive screws! You need only to loosen them. They're supposed to stay on the base cover.

4. Carefully pry the base cover using an iFixit opening tool in the crevice near the hinges. Guide the pick along the edges and slightly lift upwards as you go along.
5. Do not start from the speaker end of the edges when opening, or you may cause further damage to your device!

6. Carefully remove the base cover from the laptop.

7. Detach the tab connecting the battery to the system board using your fingers or a pair of tweezers.
8. Peel off the adhesive tab holding the cable to the device.

9. Flip the device over. Press and hold the power button for a few seconds to discharge any leftover electrical current.
10. You may leave the screen open if further repair is needed, or close it if you are only replacing the battery.

11. Dell's official service manual does not mention of the 5th screw located near the middle edge of the battery closer to the touchpad.
12. Flip the device back over.
13. Remove five 3 mm screws that are securing the battery using a Phillips #0 screwdriver.
14. Lift the battery upwards to remove it completely.
