If your laptop is unplugged and you find the battery has significantly drained overnight, one or move devices are drawing power. Windows allows some devices to continue to draw power. it is also possible that a Windows update replaced a device driver with one that is not power efficient.

Some devices that can cause to cause power drain:

USB hubs that can allow charging of devices
Thunderbolt port that can be used to dock with
The Intel Management Engine may tasks some device to maintain power.

Run the following command from the windows administrators command prompt

powercfg -devicequery wake_armed

for example the following devices are enabled even if the PC is turned off

They are all drawing power EVEN WHEN LAPTOP IS TURNED OFF.

You can disable these devices using the device manager as explained in step 1 here
