This guide shows you how to replace the CMOS battery in your Dell XPS 15 9575 laptop.
The CMOS battery powers your laptop's BIOS firmware, which is responsible for booting up your computer and configuring data flow.
You can tell if your CMOS battery has died if your laptop has difficulty booting up, if drivers disappear, and if your laptop's date and time are incorrect.
Check out the Dell XPS 9575 Troubleshooting page for more help narrowing down your issues to the CMOS battery.
Before you begin this repair, turn off your laptop and unplug it from the charging adapter. As an extra precaution, unplug the battery connector from the motherboard or remove the battery before you start.
