Windows 10 won't wake up from sleep

[Melvin Butt]

I have power settings to shut the screen off after 15 min. and put PC to sleep after 20 min. After returning to the PC after more than 20 minutes the PC won't wake up when I move the mouse or type on the keyboard. How do I wake the PC? This only happened since I installed Windows 10.

Thanks
Mel

It is probably the hibernate function holding it. You could try, to wake it up, just briefly touching the on/off button.
However, if you have no interest in the hibernation, you could, as I do, turn it off.
Right click the start icon
Select the Command Prompt (Admin)
Copy and paste powercfg /h off

If you have any apprehension about this, repeat the process but substitute the "Off" for" ON"

I may have the answer. Go Settings, System and then Power and Sleep, then Additional Power Settings. Will probably show Balanced, click on change plan settings. Assume we've all opted for computer never turning off the display and never going to sleep. Now click on Change Advanced Power Settings, click on Hard Disk. My computer had been set, by default, to turn the Hard Disk off after 20 minutes. Now changed it to 180 minutes

Same problem: machine can't wake up from sleep mode

I changed the assignment of "Power Button" in "Advanced Settings" from "Sleep" to anything else. Sadly "Wakeup" is not an option. Once I reassigned the Power Button to "Do nothing" a couple of mouse clicks successfully ended Sleep Mode. Running

Windows10 on an HP Envy 23. Did not update any drivers or software for this fix.

I got to the needed settings this way:

Windows Key or select Windows icon
Settings
Power & Sleep
Additional power settings
"Preferred plan(s)" is pre-selected as "Balanced" and I did not change it
Select "Choose what the power buttons do" on the LHS vertical menu
Change assignment from "Sleep" to "Turn off power" (this selection was my choice but there are others you may prefer)

Yes this was a very frustrating problem

y HP was updated to windows 10 pro recently
then got 2 problems simultaneously :

1.my HP won't shutdown (black screen but the on/off button indicator keep on)

I did these steps, it worked...

- go to "control panel"
- click " system and security" or "hardware ans sound"
- click " power options"
- on the left side of the screen, click "choose what the power button does"
- click "change settings that are currently unavailable"
- on shutdown settings, uncheck "turn on fast startup (recommended)"
- click "save changes"

2.after sleep mode, my HP won't wakeup (screen keep black when the on/off button indicator is on)

do these steps

- go to "control panel"
- click " system and security" or "hardware ans sound"
- click " power options"
- on the left side of the screen, click "choose what the power button does"
- click "change settings that are currently unavailable"
- on shutdown settings, uncheck "turn on fast startup (recommended)"
- on password protect when wakeup, click "don't require a password"

restart your computer, when you find its worked
do the final steps to re-active power options, as follows:
