Bluetooth.ps1

Description

This script configures the computer to automatically disable Bluetooth when the computer goes to sleep, and enables Bluetooth again when it wakes.

It uses PowerShell to install two tasks in the Task Scheduler. The tasks trigger on Kernel Power events that signal the computer is entering and exiting Modern Standby.

The original PowerShell code to change the Bluetooth state was written by u/mkdr and shared in a reply on Laptop in sleep mode but bluetooth still on???. This script expands on that and adds a few quality of life features like an automated (un)install of the Task Scheduler tasks.

Disclaimer

Important

Your mileage may vary. It's possible the computer enters sleep before the task manages to disable Bluetooth. If that happens, your computer will, unfortunately, have Bluetooth enabled during sleep. Bluetooth usually then turns off and on again when waking, but also sometimes stays off and needs to be manually enabled again.

Requirements

• Windows 10 / 11
• PowerShell 5.1 (comes pre-installed with Windows)
• Modern Standby (if you're using legacy S3 sleep states you probably don't need this script)

Usage

1. Download Bluetooth.ps1 (make sure to save it as a .ps1 file).
2. Copy it to a permanent location (e.g. your home directory %USERPROFILE% or C:\, anywhere where it won't be deleted).
3. Use Explorer and find it in the folder from step 2 where you copied it to permanently.
4. Right-click the file and choose Run with PowerShell.
5. Allow administrative privileges when asked.
6. Choose Install (or any other action you want).
7. Done, the script is now active (but remember the Disclaimer).

Caution

If you want to delete the Bluetooth.ps1 file, do not forget to first run the script and select Uninstall to remove the tasks in Task Scheduler.
