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.
