XPS 13 9365 = Sleep and Hibernate problem after Fall creator, computer goes to AIRPLANE mode

To be sure, I re-enabled the SATA controller in the Bios and my system reverted back to 2% per hour and 0% Hardware in Drips.  

You do not have to reinstall to change a M.2 drive to AHCI or disabled but you do need to use the msconfig.exe procedure to allow the system to reboot into Safe Mode after changing the controller.

I don't know which M.2 drive you have but some may not work as well as NVMe.  I was told the new Microsoft NVMe driver is better but you may lose some performance with certain drives.

Here is the link, let me know if you get the report OK.  The last 3 modern standby sessions were all done with hibernation set to never.  In the first, the "Disconnect from network on battery" was never.  The second was "Let Windows handle" and the last was to always disconnect.

Saltgrass,

That is remarkable! you're drawing about half my normal draw! That would make my laptop sleep go from 2 days to 4!  or about 6 days with a healthy battery that's reasonable. I'll take it! I'm running with the toshiba XG4 512GB drive. I'll try the switch later today. Can I share your sleep study with my Dell support ticket? I think they'd be very interested in this since I've managed to get them in contact with the Engineering team that maintains the 9365.

I've got the sleep study from you, so you can take that down now, thank you.

I haven't had a chance to take a performance report yet but my first sleep study with it changed over is quite a savings 375mw

  START TIME DURATION STATE ENERGY CHANGE CHANGE RATE % LOW POWER STATE TIME % CAPACITY REMAINING AT START  

I am not fully aware of the procedure. I used msconfig to set it to reboot into safe mode. Upon rebooting I disabled the sata controller. and then let it reboot into safe mode. that worked fine. I didn't see much to do so I rebooted back to normal and that worked. I haven't updated any drivers at this point. What are the next steps? The machine seems to run alright.

Saltgrass, I owe you a drink, seriously.

I'm not complaining I'll take a draw of 203mw which would give near 8 days on a fresh battery. My battery capacity is at about 27000mwh so.. that's why it's still near 1%/hr

Thanks All for your help  i have the same  issue  with this model  of laptop  XPS 9365   and  the RTC Reset solve the problem . 

The main problem was  that laptop  doesn´t shutdown and the battery drained all . 

some issues with  the bitlocker recovery but at the end   turn on enable  secure boot   resolves that . 

Great Thread  Great Solution  and Great work .,...

The new Bios update 1.3.1 does not seem to cause any problems as before.

i have the exact same problem after fall creators update. airplane mode and no hibernation. shut down is only possible when unchecking the fast boot option... It really **bleep** almost 6 month after the release of the 1709. 

new bios 1.31 did not change nothing

my solution: go back to previous windows build and be bothered by windows update notifications... 

i guess nobody here has found a simple one click solution yet right? 

Please DELL do something. 

EDIT it seems there is some kind of solution. It would be really cool if this is put in the title or so. Because its kind of a long thread to read through. However, whoever is responsible for this should get paid by dell if he/she not already is.

Tried it now... RTC reset did not change anything.

Can anyone tell for whom it worked on which BIOS version you reset ur RTC?

I had 1.3.1 installed when i updated to FCU and the same problem occurred, but the fix does not work.

Maybe i should try to downgrade the bios and reset the RTC and hope that the problem is solved. 

right now the FCU is not usable. it literally kills the battery. i only have the 1.2.1 Bios. is there a way to get back the older ones?

actually i found the 1.1 in my trash bin installed it and ran the RTC reset. 

At the first reboot i was in airplane mode again and i thought **bleep**... but then i tried to hibernate and come back to see whether i will be again in airplane mode. But actually it worked now.

So for everyone who already has installed the 1.3.1. For me the fix did not work on that version. I downgraded to 1.1 applied the fix and it worked. it's hilarious. 

Now i will go back to the newest version of the bios. 

Poor performance by dell, since also i was talking to some of their support dudes, without any result.

EDIT: 

After some restarts same behaviour as before. No hibernation, airplane mode occurs and shut down does not work. Only solution. Rollback to preivous Windows version 1703

For me the RTC reset does not work. The behaviour reoccurrs every time. I cannot stand it. Every week i need to do the rollback, because Windows automatically updates itself. its terrible. 

Could someone exactly describe under which circumstances the RTC reset resolved the issues? 

Thanks!
