I have an Acer Aspire e5-575g-53vg that is about one year old running Windows 10. My only modification is a recent screen replacement after I cracked it closing it on a pen. Recently I have noticed my laptop has started going to sleep (screen turns black, desktop state is still saved) without warning. I have noticed that this occurs only when I am using my laptop on my lap, and seemingly more frequently at odd angles, like when my knees are up and the body of the laptop is held at more of an upright angle than vertically. I wonder if it is a hardware problem but I would have no idea where to start to troubleshoot it.
 
Solution
Try checking the cable that connects the display. Disconnect it completely (at both ends) and then reconnect it. See if that resolves it, as a loose connection can easily cause this.
