Introdução
If your Dell Latitude 7285 2-in-1 has trouble turning on, shuts down unexpectedly, or no longer holds a charge, the internal battery may have reached the end of its lifespan. Lithium-ion batteries degrade over time with repeated charge cycles, and once the battery can no longer store adequate power, replacement becomes necessary.
To access the battery, you’ll need to remove the display panel from the tablet.
Make sure to power off the device completely, remove the detachable keyboard, and unplug the charger before beginning this repair.
