XPS 15 7590 - Bluetooth option to (not) wake the computer grayed out
This is a one week old 7590. The Bluetooth mouse wakes the computer from Sleep mode on any movement, effectively making Sleep unavailable (and potentially causing the computer to overheat if ventilation is blocked).
The 'Bluetooth Properties' menu shows "Allow this device to wake the computer", but it is grayed out. I've experimented with pretty much every setting I could find (there is no power management tab associated with the mouse device) to no avail.
Checking "Allow the computer to turn off this device..." doesn't help.
Is there a fix for this (short of using Hibernate instead)?

Bluetooth does not control the wake up option. The Mouse does--Device Manager, Mice & Pointing Devices, Your Mouse, Properties, Power Management.

Thanks for the suggestion.
Unfortunately, as noted there is no Power Management tab associated with any of the items under "Mice and other pointing devices".

After some research, it appears that this is due to a Microsoft Windows 10 "improvement" called Modern Standby.
Modern Standby is an attempt by Microsoft to make computers act like cell phones, and perform background processing while "asleep" (but not really asleep). Unfortunately, Microsoft did not appear to have taken into account that laptops/notebooks generate a lot more heat than do cell phones.
https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby
According to Microsoft, to change this after the the OS has been installed requires a fresh installation:
"You cannot switch between S3 and Modern Standby by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install."
Maybe Dell could ship computers with traditional S3 standby enabled instead of Modern Standby, but that is a moot point...

Hi,
Open Device Manager, by pressing Windows Key + R key combination and inputting devmgmt.msc in the Run dialog box and hit Enter.
In the Device Manager, expand the Mice and other pointing devices, right-click on the device and select Properties for which you’re facing the issue.
Now in the Properties window, switch to Details tab, select the Property as Driver Key and could you please check the Value(Ending value) Or please share a picture so that we can have it reviewed.

Thanks for the reply. It would be great if it turns out to be a driver issue, and not a result of Microsoft "Modern Standby."
I'm assuming you want the mouse associated with Bluetooth, per below. (There are two other HID-compliant mice, both on "I2C HID Device" and a PS/2-Compatible mouse.)
For this device:

For the sake of others experiencing this serious bug, Dell Support confirmed that the issue is due to Microsoft's Modern Standby "feature".
The response indicated: "In this Windows feature, the system is designed to wake up if there is any background activity trigger (that can include wireless connections, Windows updates, system maintenance, etc)."
The suggested workaround is to use Hibernate instead of Sleep.
