My Dell XPS 13 9350 has been shutting down instead of sleeping (when lid closed or power button pressed) since the last update from the Dell Update app.
Prior to this, I was also getting the laptop going into flight mode when it went to sleep.
Any suggestions regarding each of the above issues?
Thanks for writing to us.
Please check the power settings options and also under advanced power settings and change as needed.
Do update the BIOS and video drivers and let us know how it goes.
If none works, then try doing a system restore to an earlier date when the system was working fine.
Do provide us your system tag#, email address and name via private message,by clicking on my name in blue and then select send a private message
I actually fixed it myself prior to your advice.
I uninstalled the video driver. When I went to power options, there was no setting available for sleep, however the sleep was working properly.
I then reinstalled the video driver and all was working properly again.
