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.
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.
