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 as explained here. 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
Note that newer laptops use Modern Standby and are missing the Power Management option. If you are using Modern Standby then your bios is configured to use S0. Some BIOS allow S3 to be selected instead of S0. If not, then this article explains how to disable it. If you decide to try disabling using any of the methods explained, be sure to set a restore point in Windows to make it easy to return to s0 state.
