Introduction

Use this guide to replace the battery in your Dell XPS 17 9710.

Lithium-ion batteries inevitably degrade over time, so if you're noticing reduced battery life, or that your device doesn't power on without being plugged in, it's probably time to replace the battery.

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 replacement. If your battery is swollen, take appropriate precautions.

For optimal performance, after completing this guide calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your laptop until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

Tools

Step 1

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 replacement. If your battery is swollen, take appropriate precautions.
Power off and unplug your laptop.
Close the display and flip the entire laptop upside-down, with the hinge facing away from you.

Step 2

Use a Torx T5 screwdriver to remove the eight 4.4 mm-long screws that secure the lower case.
The lower case is further secured by various clips that must be released before removal.

Step 3

Insert an opening pick at the bottom left corner, between the lower case and the chassis.
Insert the flat end of a spudger into the gap created by the opening pick.
Pivot the spudger up to release the first set of retaining clips.
Repeat this process for the bottom right corner.

Step 4

Insert an opening pick into the gap created on the front edge of the laptop.
Slide the opening pick around the entire perimeter of the laptop, prying up intermittently, until the lower case fully releases from the clips on the chassis.

Step 5

The lip of the lower case is very sharp. Handle it with care, and try not to slide your fingers along any of the edges.
Lift the lower case up and off of the chassis to remove it.

Step 6

Use the flat end of a spudger to pry the battery's connector up, directly out of its socket.
Alternatively, grip the battery connector pull tab with your fingers and lift straight up to disconnect it.
During reassembly, line the connector up with the socket and push down gently with a finger to reconnect it.
The connector should seat in place with minimal resistance. If it feels difficult to reconnect, realign the connector and try again.

Step 7

Remove the seven 4.1 mm-long Phillips screws that secure the battery.

Step 8

Use the flat end of a spudger to lift the front edge of the battery until you can easily grip it with your fingers.
Whenever you use a spudger or other sharp tools near the battery, be very careful not to accidentally poke or puncture it.
Lift the battery up and out of its recess to remove it.
