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