Windows 10 tip of the day: Why does my battery drain while sleeping?

Does your laptop or tablet run out of battery while it’s supposed to be asleep?

You can find out why thanks to a fairly obscure but relatively new feature in Windows.

Step 1: Open a command prompt in adminstrative mode

Step 2: Go to a temp directory (like cd\temp)

Step 3: Type powercfig /SleepStudy

This will create a file in the current directory.  Open that file in your web browser and you will find out why.

Common causes:

  1. Notifications. Even while sleeping, the Windows notification system (WNS) does stuff.  Turn off as many unnecessary notifications as possible.
  2. Your type cover can wake the machine inadvertently.
  3. Your network card. Make sure you have the latest firmware and network drivers.

Good luck!

Good tips, Brad!

Does the title of the post infer a daily tip? That would be so cool!

Not daily but frequently I hope.

Also if you disable your camera in the hardware, NSACIAFBI can't use it to spy on your every move, you fucking terrorist.

Better your battery drain while sleeping than your bladder.

Apparently this only works if your computer supports connected standby. http://www.howtogeek.com/217255/use-the-hidden-powercfg-tool-to-optimize-battery-life-on-windows/
