Additionally, something to tell me whether my PC will go to sleep or not if left alone. OP's problem happens to me every so often that I need to make sure the PC is indeed going to sleep before heading out.
- monkeybutton 4y agoNothing like packing up your laptop at the end of the day, clicking "sleep" and wondering if it actually will cooperate or if you have open it back up and close random tabs and programs till it does,then waiting for the fan to audibly stop before putting it into a bag!
- shbooms 4y agoit's gotten to the point now where laptop manufacturers tell you not to put sleeping/hibernating laptop into a bag at all due to amount of heat they still generate even while sleeping [0]. Only those that are fully shut down should be placed in a bag (according to them).

- monkeybutton 4y agoI miss hibernation. Real, write the contents of RAM to disk and shut-off completely type of hibernation.
- mike_hock 4y agoMine still does that.
- sameerds 4y agoI am confused. It's still around, right? It might be disabled by default on Windows, but you can always modify the power setting to enable hybernation? I set mine up and replaced "sleep" with "hibernate" in every setting I could find, like power button, lid close, idle timeout.
- em3rgent0rdr 4y agoAs I understand on current windows, the normal power off is actually hibernate.
- lupire 4y agoThe problem is with sleep (and the "active" sleep "S0 Low Power" that will check email) and Modern Standby, which uses software to choose when to Hibernate, so might not. Hibernate S4 itself is fine, except the risk of physically triggering wakeup.
- Firmwarrior 4y agoI think on Windows you can run powercfg /requests I'm not sure about linux or Mac though
- ksherlock 4y agoOn MacOS, Activity Monitor has a "Preventing Sleep" column. From the command line, "pmset -g" or "pmset -g assertions" has useful information.
- lupire 4y agoNow we need a menu appplet, cute icon, and name like Lullaby.
- Too 4y agoAnother super useful powercfg flag is /lastwake to tell you why the computer woke up from sleep. Has helped me identify flaky input peripherals or timers many times. Worst was an HP laptop with a wonky touch bar for media controls, that would frequently ghost press and wake the computer, even when in hibernate and with the lid closed.
