Last July I upgraded my EliteBook 8540w from Windows 7 to Windows 10. I had to solve some small problems, but afterwards everythink works fine, except hibernation. There are no special drivers for Windows 10 and this laptop in the HP web (all drivers are for Windows 7, even if they work fine with Windows 10). Is there any way to manage to activate hibernation in EliteBook 8540w with Windows 10 installed?
