Dell Latitude 3410 Battery Issue
I have a Dell Latitude 3410 and my battery has started acting weird. Twice now it has suddenly dropped from around 36–38% straight to 6%, and Windows immediately showed the low battery warning. While charging, it also stayed stuck around 78% for a while and then suddenly jumped to 100%.
I checked the battery report and it actually recorded the sudden drop. Battery health is around 86%, and my BIOS is already up to date. Does this sound like a bad battery, a calibration issue, or something else? Has anyone experienced this before?
