Monitor turns off after 2 minutes inactivity

My laptop monitor turning off after 1 or 2 minutes of inactivity. I have changed all power settings to appropriate times. At times, normally after a fresh restart, my screen saver kicks in correctly. However, after a few times of working correctly, my monitor begins to turn off again.

Here is the solution that worked out for me:

1. Click on the windows icon 
2. Type regedit 
3. Right-click on regedit icon, click Run as administrator 
4. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 
5. Double click on Attributes 
6. Enter number 2. 
7. Go to Advanced power settings (click on Windows button, write power options, click on Power Options, in the selected plan click on the Change plan settings, click on the Change advanced power settings). 
8. Click on the Change settings that are currently unavailable 
9. Click Sleep, then System unattended sleep timeout, then change these settings from 2 Minutes to 20 for example. That's it!
