@legion02, I dont use sleep, I shut down the system, more if I put it in a bag to carry it to an other site. It's logical that the system still in Standby also need ventilation.
With modern systems with an SSD a Cold start is only a few seconds slower than to start from Sleep mode, because of this the last mode isnt really necessary, apart a cold start from power off avoid a lot of crap in memory and reset the counter of using time to zero, save battery and is healthier for the system.
No, it doesn't make sense that a system in sandby would need ventilation. The power draw is very low (not enough to need cooling).
The issue isn't that it's heating up in standby, the issue is that the system wakes from sleep for no reason within the bag.
This did happen to a lesser extent with the older, slower sleep method (S3 sleep), but recent Intel chips and UEFI firmwares have disabled this.
@kylemsguy @pizzahoe @mechoman444 @catfish @frostwhitewolf @CorruptBuddha @legion02, maybe, it is clear that the standby power is very low, depending on the active modules, and that it does not need much cooling.
Although in a closed space with the ventilation slits covered, it is possible that heat can accumulate. Normally for the laptop to wake up from standby requires a clear intervention, such as pressing a key or opening the screen, not very likely when in a case
That's the entire issue. Windows laptops with modern standby will wake from sleep without user intervention. It's a bug that still hasn't been fixed.
@kylemsguy @pizzahoe @mechoman444 @catfish @frostwhitewolf @CorruptBuddha @legion02, the only cause may be that some process is still running. In Windows quite possible with so many telemetry and threads of some stupid services, which causes so many new words that you invent to disable them on a new PC.
If the default configuration causes random wakeups that drain the battery while it's in my bag, then it's a bug in the OS. This should never happen.
@kylemsguy @pizzahoe @catfish @frostwhitewolf @CorruptBuddha @legion02,It sure is a bug if the system wakes up without user intervention, this shouldn't happen.
But I think that the cause is that some service remains active, this would explain that the system wakes up but also the heating.
Therefore, while MS does not fix this, it would be advisable to shut down the system to avoid this. This, if you use an SSD is not such a big difference to boot it.
It's great that those considerations work for how you use a laptop, but that's not how me or my colleagues or family members expect them to work.
Sleep should work the way it's advertised and does work on Macs. The only significant voltage drain should be the memory modules that need it to maintain state. It used to work this way on windows and Linux for that matter.
@legion02, and it usually does on Windows and Linux as well, and it shouldn't be a warm-up reason. But if it is put in a bag that prevents ventilation, even a weak voltage can heat up the Laptop. The same if it is used for example, which I see sometimes, to use it on top of a cushion or on the knees, because this covers the ventilation slits, the same also if they are covered by dust.
In any case, something is wrong if the Laptop gets hot, except in heavy use, eg in gaming or similar.
Yes, the thing that's wrong is windows modern standby.
@legion02, Yes, this confuses many that turning it off with the default power button enters a Quick Start modus, well this, in Stanby. Normally nothing happens, apart from continuing to drain battery life and naturally it can get hot if put in a bag.
This currently with an SSD does not make much sense, since there is not much difference between Cold Start and Quick Start, same as I always desactivate Hibernation and Index service, 2 of the worst Memory hogs. Index also not needed with an SSD.
