I manage a few hundred Windows notebooks. Probably about half of them have issues hibernating. Despite the fact that they are identical systems, identical image, etc. I just tell everybody to shut it down before you put it in your bag. Otherwise we end up with overheated, melted laptops. It's always been this way in my experience. Windows is certainly better than it used to be at this, but I would be willing to believe that the hardware vendors aren't implementing things properly. I guess that's the downside of not controlling your hardware.

Are you sure it is Windows not Chrome?

If you closed the lid while Chrome is running, it prevents Windows from sleeping.

Chrome has a very parasitic relationship with it's host OS's. Stopped using it when it halved the amount of hours a brand new MacBook lasted on a battery. My apologies for the webdevs that have to maintain Safari compatibility for me but the difference is just too big to ignore.

While it probably still loses to Safari in a Mac battery benchmark overall, Chrome is much better today in this regard than it was a few years ago - the gap isn't what it once was.

At this level, do you have "premium" access to Microsoft support? At some point the company actually listens to you, right? What happens when you contact them, get ahold of a person, and say "yeah we paid you $300k in license fees the last 3 years. This pretty basic feature of your product doesn't work. Can you fix it for us?"

Do they really just tell you to go pound sand when a corporate client asks them for support?

I'm guessing they tell you to call Dell or HP because that's who's responsible for whether hibernation works on their specific machines.

What enterprise security tools do these systems run? What Anti-virus? Systems management? Logging? Hardware diagnostics? What group policies have you set?

Windows is far from perfect, but these other tools that are supposed to help you are more often the source of site-wide problems like what you've described.
