Windows 10 Sleep/Lock Problem

This advice did not work for me.

Some one wrote this.... just upgraded to Windows 10 and my monitor will not come back from Sleep or Lock Mode without turning off the computer and rebooting.

I am and I am having the same problem with not coming back from sleep mode. If I press the on off button the monitor will come back on
but everything is locked up and then I have to turn it off on the tower. And then turn it back on. What I have found to work is turning the power options to never turn off or sleep and then just turn off the
monitor during the day and then just shut it off at night.

 

PC hibernates / goes into sleep mode upon logout / screen lock

I am using my work computer. It's a laptop with a power connection (not running on battery.) The laptop is hocked up to two monitors (a total of three monitors, counting the laptop's own screen - I usually keep my laptop closed, however.)
Since I am at work I always lock the screen when I leave my computer. (I use the windows+L shortcut to lock the screen.) This all works fine.

However, after about a minute the computer goes into sleep mode / hibernation. At least I think it does, because the two monitors goes black - and it takes a few seconds to "wake up the system" (the monitors doesn't come back to life immediately when I press a key on the keyboard / move the mouse, as they would if a screen saver was active.)
This is very annoying if I step away from my computer for only a short while (like going to the bathroom.)

Here's what I want:
With power (not running on battery):
When I lock the screen, I want the screen to stay on for 1 minute, then go to screen saver for 15 minutes, then go to hibernation/sleep mode.

Without power (running on battery):
When I lock the screen, I want the screen to stay on for 1 minute, then go to screen saver for 5 minutes, then go to hibernation/sleep mode.

My best bet is that this is some sort of power saving scheme thingie, but I can't seem to figure out how to configure it to do what I want. Can someone please help me with a step-by-step guide to configure my system the way I want? Thank you.
