Current work sent me a Dell Lattitide 7330 with Windows 10 Enterprise. It's not a bad little machine. Light, small, obviously designed to be portable. One of the first things I noticed was after I closed the lid to suspend on a full battery, walked 20 minutes to the library intending to work there and opened it to find the battery down to 80% already! Not a great start. As the lid settings are to sleep on closing the lid when on battery, I figured out the same idea as the article: Unplug power and external display first, wait a bit, then close the lid. I thought that was working, but after enough tries doing that, only to find it stayijg hot for hours in my bag, I'm confident the unplug-then-sleep method is unreliable. I've tried going to the Start menu's power icon and clicking 'sleep". That often doesn't work. It turns things off, eventually, but the fan keeps going and it stays hot about half the time. Sometimes it doesn't even bother pretending, and the power light stays on. I've tried to change the lid settings to Hibernate. Not available: Lid settings are set by remote policy, not user configurable except by local admin access to override policy, which I don't have. Under the Start menu's power icon there is no Hibernate option, of course. Doing "powercfg /a" as in the video, I see S1, S2, S3 and Hybrid Sleep are all "does not support". I'm reluctant to change BIOS settings on a work laptop managed remotely with a strict security policy. It seems I'm doomed to take the laptop out in the library and coffee shops and find it drained and very hot sometimes, even if I charged it before going out. But unpredictably. So I haven't found a reliable way to make this Dell laptop sleep yet. Hibernate and S3 are unavailable. I suspect Shut Down might be the only option, but it's a bit drastic and I'm not confident even that will always work.
