This sleep thing appears to be nonexistent on specific laptops. For the Dell XPS 9500, pressing the power button will simply turn off the display, making you think that the laptop is asleep but it's not. Opening the lid will turn the display on and will simply be where you left off. Hence, I have read a lot of things online where many owners have put the laptop in their bag and be confused why their laptop is so hot/warm. I believe it's also a Windows version specific thing. On Windows 10 version 2004 and after, supposedly this sleep state got eliminated so that the CsEnabled registry entry doesn't work anymore to disable s0, what is known as modern standby, even if you add it. Interestingly enough, my old laptop was still able to sleep just fine despite upgrading to version 2004. Then again, it's a Dell XPS 9560, so again it just might be certain laptop models that don't have it.
In any case, I think it's really dumb that it's not available for my new laptop and so I guess I have no choice but to either hibernate or shut it down. That's a shame too. I'm very used to putting my laptop on standby/sleep and then quickly resuming where I left off. Hibernate is mostly the same, the difference is that it saves way more power due to being in a much more minimal state than standby/sleep but it's also slower in continuing where you left off. Or, I might just reach out to Dell support and see if they can help me with my issue. After all, I do have a 1 year warranty, meaning until next October.
