My Dell Precision 3480 seems to lose 12% of the battery overnight. The machine is stuffed into backpack as I use the machine for field use. Never used to be a problem so I wonder if the motherboard has developed a fault.
Do you turn the laptop off before putting it into the backpack? If not, you should because if it is left on it will reduce the battery.
