For the past few days, my Acer laptop keeps shutting down whenever I close the lid or when I try to put it to sleep. When I choose "sleep" and I close the lid, and when I open it again, it takes a long time to turn on and the acer logo appears and it reboots. When I open my browser, it says "system did not shut down properly" or something like that. I'm not sure if my computer is crashing every time I close the lid or not. I set "choose what close the lid does" and "choose what the power buttons do" in the power options correctly but it still doesn't work. I also updated the BIOS for my laptop. I've seen some people say that the laptop shutting down problem is sometimes because of the Intel Management Engine Interface but my laptop doesn't even have the Intel section in device manager. Please help me fix my laptop from shutting down when I press the sleep mode and also shutting down whenever I close the lid.
