Been using this Laptop over 3 years (Acer V3 731). In all that time Hibernate has worked. A couple of days ago it just stopped working. I've added no softeare or peripherals. I've googled for hours and tried all suggestions but nothing has worked. All my settings are set to Hibernate and Hibernate appears in the shutdown menu. Looked through the BIOS but see nothing that should affect this problem. Don't know what to do next. If it worked for over three years it should be able to work again. Any help will be very appreciated--I really miss it.
