Does your XPS 15 9570 get hot and drain its battery while asleep? Dell has a workaround, but you may not like it.
Has your XPS 15 9570 overheated or had high battery drain while asleep? If not, there have been multiple reports of such behaviour occurring following the removal of S3 sleep last year. Dell is reportedly working towards somehow fixing the functionality that it removed, but that is no consolation for those who have upgraded their XPS 15 9570 beyond BIOS 1.3.0 and are being forced to use Modern Standby. Redditors like u/mkdr have done great work to demonstrate how poorly implemented Modern Standby is on the XPS 15 9570, but until now there had been official word on the issue.
Dell is now suggesting a workaround for high battery drain and overheating before it finds a permanent solution, which subverts using Modern Standby altogether:
Research modern standby and turn it off, that should solve.
This may sound simple, but it further diminishes the functionality of an expensive laptop. If you disable Modern Standby and switch to a different system sleeping state, then be prepared to make compromises. System Power State S1 and S2 both have higher power consumption than Modern Standby according to Microsoft, and your machine will take at least a second or two longer to wake up too. Switching to System Power State S4, also known as hibernation, eliminates the power consumption issue but the system must load from a hibernation file. These are often large, and you may have to restart your device if the hibernation file cannot be loaded.
Moreover, waking from hibernation takes a lot longer too. Lastly, you could simply switch off your machine every time you put it to sleep. Again, this is wholly inconvenient and is incongruous for a laptop as expensive as the XPS 15 9570.
In short, there is no good solution here and disabling Modern Standby is not one of them. Frank Azor has also made another suggestion though; propose his sacking. He could do with a holiday, apparently.
