I'd suggest you check Battery's status and health in the Battery Meter App. Please right click battery icon at taskbar, and then click on battery health. It should say Your Battery Is Performing Normally, if it say anything else then you most likely need a new one. Secondly, check battery status, if there's a checkmark in box by Enable Dell Extended Battery Life then uncheck it and restart computer.
