Here’s how to do it. It’s quite a few steps but if you do them one by one it should be manageable and will hopefully resolve the blank laptop screen issue for you:
Click start and type ‘power’ in or use the taskbar search if you have this enabled.
On the right choose ‘additional power settings’.
Choose ‘change plan settings’ then ‘change advanced power settings’.
Under the sleep option on the list, set allow hybrid sleep to off for both AC and batteries.
Come out of the plan settings and on the left of the power options window go to choose what the power buttons do. Click change settings that are currently unavailable, then uncheck turn on fast startup.
Save the changes, close all windows and reboot your computer.
This should hopefully fix the problem for you at the expense of a few seconds extra boot time
