For the past month, I've been unable to put my laptop to sleep/hibernate or even shutdown through the power options in the start menu and the closing of the lid. However, if i use the laptop for a small duration (~1hr) it will act normally and the methods above work, but if i use it for a long period it doesn't. I have tried resetting my BIOS to the defaults, changing power options, unchecking fast start-up and updating drivers but nothing seems to work. My laptop is an Acer Aspire V3 and I am running Windows 10. Please help!
