How to Disable Bluetooth in Modern Standby (S0 Sleep)

Has anyone figured out how to turn off Bluetooth when the laptop enters Modern Standby (S0 sleep)?

My new Dell XPS 9640 keeps turning back on after putting it in sleep. From event viewer I found it was waking due to the Bluetooth mouse. An option to turn off Bluetooth in S0 sleep seems to be a no brainer - Windows has the option to turn off Network Connectivity in S0 sleep, but not Bluetooth that I can find.

My searches haven't turned up any option or regedit which disables Bluetooth in S0 sleep. I did find a script for the problem which uses task scheduler, but it fails to work as the laptop enters sleep before the script runs. I set the wireless card to disable "allow the device to wake the computer" and enable "allow the computer to turn off" the WiFi/Bluetooth card and it didn't help.

On my previous Dell I just enabled S3 sleep and it worked. However, the XPS 9640 doesn't have S3 sleep support. If I disable Modern Standby (S0 sleep), the computer will only hibernate.

I'm not happy with a low battery and an overheated laptop in the bag if I forget to manually disable the Bluetooth before putting it in standby.

I wonder if this issue is dependent upon the BIOS. On my Lenovo laptop, I can NOT get it to come out of Modern Standby with a Bluetooth mouse while the lid is closed. With the lid open, the Bluetooth mouse will bring the laptop out of standby.

Kind of hard to notice if a laptop wakes with the lid closed. That said, same here with my Lenovo laptop.... no wake issues, Testing it now with the lid open and laptop put in sleep mode. This is Lenovo's latest ThinkPad X1 Carbon laptop, so yeah, modern standby supported.

With that, @ the OP, if the laptop is still under warranty, you might have it checked out. The other alternative is the check the Dell forums.

Good luck.

I'm sure that this varies from laptop to laptop, but it is super easy on mine. On the side of the laptop is located an LED. Steady on is powered on and fully awake. When it flashes slowly it is in standby.

Welcome to the forum.

If you’re switched on enough (above my head) maybe you could disable hibernation and create a task to start a string of batch files. Would take some work and searching in that direction

Agree - I plan to check with Dell using my warranty, but don't hold out much hope for them to have a fix :(

Good idea - I may try this as a last resort.

Same here - 2024 ThinkPad Carbon X1 (12th Gen). And I didn't think about it from that perspective until you clarified.
