Windows 10: Laptop takes a long time to turn on screen after waking up from sleep mode

As the title states, I have a Lenovo Legion Y520 that takes 5-6 seconds to turn on the screen after I open the lid to wake it up from sleep mode. Usually I just put up with it, but it took an exceptionally long 15 seconds today. I thought this was typical Windows behavior until I saw my sister open her sleeping XPS 15's lid and the screen turned on in, like, a second.

I'm running Windows 10 1909.

Here are some of the specs, if it helps:

• 
  Core i7 7700HQ
  
  
• 
  16 GB RAM
  
  
• 
  GTX 1050 Ti
  
  
• 
  C: drive is a Samsung 256 GB PCIe NVMe SSD.
  

I might be wrong, but I think the issue is display-related. I say this because, if I turn on the keyboard backlight and close the lid, it'll turn on immediately when I open the lid.

Windows 10 Upgrade 1903 64 bit Sleep Wakes Up on Multiple Computers

Someone suggested I look at all the drivers list before and after the upgrade. I did, nothing found/changed in drivers.

What I did discover was that after the KB4503327 upgrade, if I put the computer to sleep mode (via power menu,) I discovered the computer wakes up after the minutes set in the "turn off screen".
So, if the screen shutoff were five minutes and I put the computer to sleep, it would wake up after that amount of time, then turn the screens off after another time period of five minutes.

At this point, I have set the screen turn-off to "never" and any other sleep mode to "never".
Then, when I put the computer to sleep, it stays asleep.

This issue was never seen until this OS upgrade was installed in the system.

My next step is to upgrade the video adapter (something from 2007) to a new and different model adapter to see if that corrects this issue, or not. For now, my work-around is to set "never" in "sleep mode".
