Windows locking into sleep mode

Question

2 days ago i upgraded my windows 10 to build 1903 , since then ,

randomly and during any activity (gaming , watching a video ..etc) , 

screen with the word "locking" in the middle appears for half a second and my laptop goes into sleep mode 

and then i have to turn it on again 

this never happened before the update , i tried to reset and fresh start but, nothing worked , and now i can't get back to previous build 

what do i do ? 

HELP , PLEASE

SOLUTION 

Hey guys

So, I solved the issue (for me, at least) a long time ago but forgot to report back. My apologies

Basically,

Settings -> power and sleep -> additional power settings -> change advanced power settings -> battery

Then, change critical battery action and low battery action to do nothing both on battery and plugged in

I don't know if others already solved the problem In a different way, but i Hope that helps

Have a good day

It's a concern because there is no message "Locking" that I have seen in WIndows 10, and the only way to lock is to use the Lock button in Sign Out options from your Profile link above the Start button, which essentially puts up the Lock Screen to force signing in again.

Look through Settings > Apps > Apps & Features list to see if there's anything installed for Locking the screen.

Did you run full scan with Download and install Malwarebytes from https://www.malwarebytes.com/mwb-download/ ?

Then check System files for damage by running System File Checker from https://www.lifewire.com/how-to-use-sfc-scannow...

I gave you every other thing possible for locking, sleeping, suspending the screen and none of those were engaged.

I believed you are asking for the picture of this screen? Sorry for the blurry image because this screen appeared really fast like half a sec so I have to record with my phone and cut it out from the clip. But this is technically what happened to me and everyone.

I'm sorry but it's a little strange to see even a Windows MVP like you haven't seen this screen before.

This is caused from the update, not malware. Same thing is happening to me after the update.

Answer 4

I dont have "nothing" as an option, its just hibernate or shutdown.
