Hi, 
I have an Acer Swift SF315-52, I bought last year, out of warranty for a few months now. For about a month or so after the screen timeout or after I close the lid (while powered, it won't enter sleep mode) the screen remains blank, and the keyboard is not responsive, except keys light (f8). The 2 LEDs on the left side (power and battery) are lit.
There is no other way to get out of this other than forcing a restart (hold down power key for a few seconds until shuts down).
OS is Windows 10 Pro 64-bit.
The event viewer doesn't show any critical events. However, I see no events previous to a restart (it depends on when I try to use it again). Among the first events created after forced restart is "The previous system shutdown at <time on ‎date> was unexpected".
