 info: Windows 10 home version 10.0.19042 Build 19042 
Laptop: Acer nitro

Sleepmode settings: 30 minutes on battery, 1 hour on 
electricity
Since 2 weeks my 
laptop has an issue where it enters sleepmode seemingly at random. It 
has happened three times so far. The only program I installed right 
before this started happening was bitdefender (antivirus, safepay and 
vpn software), but I’m not sure if that can have anything to do with 
this.
The first time this happened
 I was only running ms teams (and attending a meeting), and the screen 
turned off and on a few times before the device went into sleepmode. 
That would almost be normal (if there was no flicker) because I hadn’t 
touched my laptop in 15 minutes, which was my limit for sleep mode. 
After the first time I did edit the times to half an hour.
The
 second and third times it went right to sleep mode without blinking so 
they might be separate issues. I’m not sure what I was doing the second 
time, but the third time just now I was typing in a word doc while 
attending a meeting when it happened. During the 2 last times my laptop 
was plugged in and on a good surface. It didn’t seem to be overheating 
any of the times, it just seemed to be the normal temperature when I 
checked my nitrosense (program for fan control where you can see 
internal temp) afterwards.
I 
haven’t really tried to fix the issue because I don’t really know what 
is causing it, or how to find what is causing it. I did try to put my 
energy settings back to standard values, but that’s not possible because
 the button is grey. Can anyone help me find the issue and solve it?
