XPS 13 9360, Not shutting down or sleeping properly

Have you tried.

• Install official NVIDIA proprietary drivers
• Edit /etc/default/grub 

sudo nano /etc/default/grub

make sure that the GRUB_CMDLINE_LINUX line has the following items:

GRUB_CMDLINE_LINUX="nouveau.blacklist=1 acpi_osi=! acpi_osi=\"Windows 2015\" acpi_backlight=vendor mem_sleep_default=deep"

• update grub:

sudo update-grub

• reboot
• after computer has restarted, try suspending to see if it wakes up normally

I assume you're using Windows?

I had a similar issue with the 9550. Using the Event Log I found that it tried to wake up a couple hours after going to Sleep to automatically switch over to Hibernate, but work up instead (backpack hot!!!). Subsequently, it wouldn't want to Sleep/Hibernate/soft Shutdown, as you say. Hard Shutdown worked, until next occasion.

Workaround: set "Hibernate After" in advanced power profile settings to Never (0). Also reflash BIOS (can be same version), because this seems to reset something.

Mind this make time to battery dead shorter, because Sleep uses more power than Hibernate. For longer periods use Hibernate directly (but for me it isn't exactly 100% certain to wake up from it). 

This sounds like a legitimate solution - I will give it a try and let you know if it worked

@samos1111 I tried your recommended solution but it didn't work for me - I still have the same issue even after I adjusted the power settings and reflashing the bios

@samos1111 How do I check which sleep version it's using?  

Sorry, it might be an unrelated problem. Unfortunately, sleep etc issues are difficult to debug. Try checking Event Viewer / System log for suspicious events. You can also try debugging using the powercfg command options (in admin command prompt window).

Firstly, check out if your laptop is using old S3 sleep or new Modern Sleep / Connected Standby.

I'm noticing the clock on my Dell XPS keeps malfunctioning too and I'm not sure why - to restore it I have to keep going to Adjust Time & Date -------> Turn Off "Set Time Automatically" --------> Turn it back on to reset it to current time.  

Anyone have any more suggestions in regards to a resolution to this problem

I just updated BIOS to 2.11 which was released yesterday for XPS but still experiencing same issue.  Anyone have suggestions b/c it's kind of annoying to have to reset the clock and also do hard shutdowns every time.  

Hi jess2020,

Thanks for posting.  Apologies that your system is not performing as expected.

Please check for any hardware issues by running Dell SupportAssist, making note of any error messages encountered and post back.  If there are none, then it could indicate either a software or driver issue.

Try turning off Fast Startup by right clicking Start button to open Power Options>Additonal Power Settings>Choose what Power Buttons do>Change settings not available then uncheck Fast Startup, Save and Exit, restart PC, then try Shutdown. 

If you still require assistance and the system is under warranty, you may contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.

If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service request. 

@robert p I tried that before but I will try it again - I don't think it would do anything b/c it was working fine before with Fast Startup on which is the default and recommended mode for XPS systems.  I also ran SupportAssist and it hasn't detected any issues

The battery doesn't seem to be draining overnight anymore after unplugging from monitor and outlet.  There is some battery drain but it seems to be the same as if it was in sleep mode.  The start menu shut down and sleep still do not function properly.  The clock still has to be constantly reset.
