Windows 10: High power draw after waking computer from sleep

Hi,


I have a Lenovo Legion Y540 that after waking from sleep draws a lot more power than it does after a fresh restart. Below are images from a utility that monitors power draw, and you can see how how drastic a difference there is between waking from sleep and after a restart. Often, after restarting, my time remaining on battery will either double or quadruple.


After waking from sleep settled on about 16000 mW a few minutes later:




After a restart Idled around 9000 mW before dropping:

wake from sleep issue in windows 10

Hi,

Thank you for posting your reply. Apologize for the delay in response.

I suggest you to check which devices are configured to wake up the computer from sleep by following the steps below:

• Right click on Start icon and select Command Prompt (Admin).
• Type the command line below:

Powercfg /devicequery wake_armed

3. Check if the devices (Keyboard, Mouse, Ethernet cable) are listed.

If the system is not going to sleep and going to Hybernate, the only option to wake up is to press the Power button.

Hope the information is helpful.

Hi Bill,

There's a possibility that the settings that enables your Space bar to wake your computer up from sleep was reset after updating Windows. If this what had happened, we suggest that you just re-set it up. See the steps below on how to do
so:

• Press Windows key and type keyboard in.
• Click on Keyboard option and a pop-up windows should show up.
• From there, go to > Hardware tab > Properties >
  Change settings > Power management > Allow this device to wake the computer >
  OK/Apply.

Try the if the steps did work and let us know any updates.

Did all the steps exactly as shown above and "Allow this device to wake the computer" was already selected.

I think you might have miss-understood the problem. It appears that the computer is waking up, but it doesn't re-connect to my display. I have to turn off the display and turn it back on to get my display to to re-connect. This was not a problem prior to
the last Win 10 upgrade.
