XPS 13 (9365) lifting the lid wont wake from sleep

I'm not able to find any setting to change this behaviour. Closing the lid will send the laptop to sleep, but when lifting the lid it does not wake the device. The only way to wake from sleep is with the power button. 

How can I fix this?

Under device manager > system devices > ACPI lid there are no power options to configure

Under power & sleep > change advanced sleep settings > change when the device wakes or sleeps > the only lid action that can be configured is 'close'

powercfg/ wake_armed > "NONE"

powercfg/ wake_from_any > ACPI lid is listed as a device that can wake the computer. 

 

Any help appreciated. This is extremely frustrating.

Hi @pacca91, you are looking in the right area for this information and it would normally be listed under the power management tab for the ACPI lid. As there are no power management options available in the device manager for the lid, this means that the function is not supported on the system.

Thanks for the response Alan. 

Can you please provide any guidance on why this is the case? That is a very unsual and counter-intuitive design choice for a modern laptop (I would almost say it is unique to this specific device - lift to wake is a standard bit of functionality). 

Further to that, cmd inquiries suggest the ACPI lid is enabled somewhere in the system BIOS, but it has been disabled by Dell somewhere along the way. There is no physical reason why this functionality would not be supported.....

The 9365 does not go into sleep mode but a low power mode called Modern Standby.

It will go into hibernation and shutdown, but sleep is not allowed.

If you have the system in laptop mode, when the display turns off it drops into the low power mode and stays there until or if it goes into hibernation.  The display will return by tapping the space bar if the system is still in low power mode.  Such things like Cortana or an Active Pen or Bluetooth mouse may also be able to bring back the display.

The theory is a Low Power mode will save more energy than sleep but still allow the system to be Instant on.

The linked Microsoft video is older and a little out of date but does describe the operation of a Modern Standby system.

Hi @pacca91

This choice has likely been made based on chassis type, components used, i.e reed switch / HALL sensor, sensor placement, availability of space within that chassis or a combination of those factors. Ultimately the decision will be design or engineering based. I suspect it's the functionality in the HALL sensor or reed switches that we use that prevents this.

I had a look at half a dozen different notebooks between my system and my colleagues and none of them have wake on lid functionality. These were all standard notebooks rather than the 2 in 1 design of your 9365.

If the system senses the lid being closed, it's likely it can also sense it being opened ... but if it has not been configured to do anything with the latter, it will simply ignore it.

Re: XPS 13 (9365) lifting the lid wont wake from sleep

I just bought an XPS 15 9570 and was wondering about the same issue: opening my laptop won't wake it up.   This is a usability oversight for a $2000 laptop!

My MacBook Air 11" from 2013 wakes up in 2 seconds when I open its lid.
