I just bought my XPS 15-9570 with BIOS 1.2.2 installed, and I updated it to BIOS 1.3.0. I realized that the "sleep mode" option is now gone. I need to set this to "Force S3" sleep to prevent the laptop from waking up randomly, or don't go to sleep properly. So can I do that in the new BIOS?
Solved! Go to Solution.
"At this point when checking `powercfg -a` it would say S3 is supported and S0 Low Power not available."
Didn't show up for me when I first tried, but somehow it worked after the third time. Seems like it needed a proper restart in between. My laptop is now sleeping... thank you!!
The problem doesn’t occur with me so I cant reproduce it. My best guess would be to do the following:
it might be happening if the network adapter is allowed to be disabled to save power on hibernation and/or sleep. To uncheck the setting, follow the steps.
It could be that the power multimedia settings are messing with the sleep settings. I can reproduce your problem with a second screenattached by making a change in my power settings. So maybe that is set the way I set it to reproduce the problem.
Go to: Control Panel -> All Control Panel Items -> Power Options -> Edit Plan Settings.
Click on advanced power settings.
In advanced settings go to Multimedia settings -> When sharing media -> prevent idling to sleep
Not sure if this is the fix so remember how it was set before you change it.
I just logged in to say THANK YOU! I'm so happy to have normal sleep back. Last night I had charged my laptop to 100%. I got to work this morning about 10 hours later, and my laptop had 64% battery left! Found this solution, and battery life is back to what it should be. Thanks!
