Power button sleep on Creators Update

mikolajek · 21 Jun 2017

I'm running Dell XPS 15 (9550) which I use for work. Finally our admins have upgraded McAfee which used to prevent Cretors Update from coming on my machine. Since a couple of days I'm running CU then!

I have "sleep" function linked heto t power button settings (in power settings) but it has stopped working since the CU upgrade. Now when I press the power button, the laptop y powers simply powers off instead of going to sleep.

I've checked the active power plan and all other power plans and in all of them the action bound to the power button is sleep. Seems like the power management bug...

Can anyone offer some advice on this?

So just to double check, your settings look similar to the attached image?

If so, then let's try a simple quick-fix attempt.
1) Change the When I press the power button to Shut down
2) Press the Save changes button
3) Restart the computer
4) Go back to this same location and change that option back to Sleep
5) Press the Save changes button
6) Restart the computer
7) After the computer starts up, press the power button
8) What happens?

Yes, they look exactly the same:

Unfortunately, the trick doesn't seem to fix the issue

. Even though the "Sleep" option is officially set, pressing the button still poers the device off...

Try this out; see what happens:

Running troubleshooter hasn't helped either

But somehow when I connected it to my home power adapter (exactly the same as my work one), the power button acts as intended! No idea why but I'll definitely examine my work power supply.

Go to Power Options
You will see 2 Preferred plans: Balanced & Power saver

For both, do the following:
Press Change plan settings
Press Change advanced power settings
Press the plus sign next to Power buttons and lid
Press the plus sign next to Power button action
Setting: Sleep
Press the plus sign next to Sleep button action
Setting: Sleep
Press OK

Remember, do the same thing for Power saver.

If it is a work machine, your IT group most likely stopped people from using Sleep, since it actually causes laptops to burn up from overheating when they suddenly wake up in a case and there is no way to cool them off.

Thanks bro67, but it's not the case - I've double checked it with our IT.

Surprisingly when I repeated procedure suggested in the originally reply by pepanee, the issue has gone! No idea why it didn't work for the first time, but this time it did.

Many thanks for your help!!!

Cool! I'm glad it worked the second time around.

You're welcome =)

Maybe the ACPI driver updated. Dell computers are known to act quirky for power drivers.
