I can help fix your problem, just follow these steps and you will be able to shut your laptop lid and the screen will not turn off.
- Right click the battery in the bottom left and then click "Power options"
- On the option you have active, click "Change plan settings"
- Click "Change advanced power settings"
- Find where it says "Power buttons and lid" then click it
- Click "Lid close action"
- Change "On battery:" and "Plugged in:" to "Do nothing"

This should make it so when you close your laptop lid, the laptop screen will stay on and it will not fall asleep like it usually does.
Have a good day!
