Dell XPS 13 7390 Battery Replacement

Introduction

If your Dell XPS 13 7390 has lost its ability to hold a charge, you probably have a dead battery that needs to be replaced.

A working Dell XPS 13 7390 battery provides power to your computer. Laptop batteries discharge more quickly after a large number of charge cycles. If you notice that your battery is discharging faster than usual, perform a battery calibration to accurately determine its charge capacity. If you continue to notice large drops in charge percentage, you should replace your battery.

A punctured Dell XPS 13 7390 battery can start a fire. If your battery is swollen, take appropriate precautions.

Be sure to turn off your device before you begin.

I have an xps 13 7390 and when I perform step 1 - prying open the base cover - the computer turns on. I searched the internet for how to configure my PC to not automatically power on when the lid opens (even when it's only opened 1/4 of the way it tries to turn on) and my BIOS does not seem to have a Power On - Lid Open on/off option. Any suggestions? Thanks.

UPDATE - My XPS 7390 does, in fact, have a LID Power on/off option through the F2 Function. This gets you into BIOS and it was all the way at the bottom of the Power Management option. Apologies.

This guide is better and more accurate than Dell’s website. Just replaced the battery DHGH8 (4-cell 52 Wh, 7.6 V) in my XPS 7390 with no problems.
