I have an Asus Vivobook. In windows 8 I used sleep mode all the time. after the upgrade to windows 10 whenever the computer enters sleep mode either by closing the lid, automated or manual, when I wake it it restarts. I entered the BIOS and the AHPC (am I pronnouncing it right?) mode was enabled, and was the only option. I looked through the computer power options, but I can't find anything. Help someone? =]
