Question

Bluetooth saying turned off everytime I power up my Surface Pro

Ry 0

For some reason every time i open my surface pro now my arc mouse is not working but it says its connected and active with 75% battery. It's saying bluetooth is turned off but the slider is gray and slid to the right. Up until now everytime I turned on my surface it was already connected.

Hi Ry,

I understand how frustrating it is when Bluetooth is not working, especially since it used to just work and now interfering with your mouse. The Q&A Assist has given some excellent troubleshooting steps and you should try them out. In case it didn’t help, here are some other options:

1 - Disable power saving on Bluetooth (if it's available)

Right-click Start > choose Device Manager > expand Bluetooth
Double-click your adapter > look for Power Management option
Uncheck Allow the computer to turn off this device to save power
Click OK > Restart your PC and check the behavior again.

2 - Reinstall the Bluetooth driver

Go back to Device Manager > Bluetooth
Right-click your adapter > click Uninstall device
Restart your Surface > let Windows auto-install the driver.

3 - Turn off Fast Startup

Search in the taskbar and open Control Panel
In Power Options > Choose what power buttons do
Click Change settings that are currently unavailable
Uncheck Turn on fast startup > Save > restart the Surface.

4 - Reinstallation repair (keeping files and apps)

Open Settings > System > Recovery > Fix problems using Windows Update
Click Reinstall now > follow the onscreen instructions to reinstall Windows.

Disclaimer: This reinstallation can fix update issues without removing your files or applications. However, we always recommend that if you have important data, you should back it up.

If you’re not sure, let me know when you open Device Manager, does the Bluetooth adapter show normally, or does it disappear / show warning? It'll help narrow down the issue.

Haven't heard back from you for a while, Ry. If you have any updates on the situation, let me know and we will look into it together!

None of these have worked. Says Bluetooth is turned off while the slider is on then when you turn the slider to the off position it turns grey and won’t let you turn it back on

So what did you see in Device Manager? Is there a Bluetooth adapter or not?

In the meantime, open Settings > System > Troubleshoot > Other troubleshooters > Run the Bluetooth one.

Also, since you're using Surface, try running the Surface app and Surface Diagnostic Toolkit: Fix common problems using the Surface app and Surface Diagnostic Toolkit | Microsoft Support

Yes there’s a Qualcomm FastConnect 7800 Dual Bluetooth AdapterRan the troubleshooter, now running an update and I’ll let you know how it goes

Works after the restart, but once my surface wakes up after not using it for a few minutes no Bluetooth is working. All of it says connected and 100% battery including my arc mouse but none of it works. Then I turn Bluetooth off and the slider is greyed out and stuck in the off position

I admit, Ry, it’s kind of looking stale on my end too. I have some other suggestions but if they also don’t work, sorry but I’m also out of ideas at the moment. We may have to wait and see if other members of the community have better solutions to this.

1 - Force a full power reset for Surface

Shut down your Surface Pro

Hold Power button for 20 seconds

Let it turn on and off > Release when done

Wait for at least 10 seconds, then turn it back on.

Note: If you have an older gen Surface Pro (before the 5th), follow the steps in this guide Force a shutdown and restart your Surface | Microsoft Support

2 - Manually install Surface-specific drivers

Go to: Download drivers and firmware for Surface Pro | Microsoft Support

Select your Surface Pro model > click Download

Install the package and restart.

3 - Roll back Bluetooth driver (if still possible)

Since the issue starts recently, it might be the newer driver causing problem

Open Device Manager > right-click Qualcomm FastConnect 7800…

Open Properties > Driver tab > Roll Back Driver (if available).

4 - Disable Modern Standby

Open Command Prompt (Admin) and run: powercfg /a

Check if you see S0 Low Power Idle (Modern Standby)

If yes, press Win + R > type regedit > press Enter to open Registry Editor

Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

Right-click Power folder > add new DWORD:

Name: PlatformAoAcOverride

Value: 0

Restart your PC. If it doesn't change anything, remove it briefly.

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, first check out How to back up and restore the registry in Windows - Microsoft Support

Other possible causes I can think of include physical hardware wear or a regression introduced by the latest Bluetooth update. In the latter case, unfortunately the resolution would be to wait for fixes delivered through Surface/Windows Update, or Qualcomm.

Use the following steps to get the Surface Arc Mouse and Bluetooth working reliably again.

Confirm the mouse is actually paired and powered
- Press and hold the pairing button on the bottom of the Arc Mouse for 5–7 seconds, then release.
- If the light blinks, the mouse has power. If it does not, check or replace the batteries.
- While the light is blinking, on the Surface Pro go to Start > Settings > Bluetooth & devices and confirm the mouse appears as Connected. If it does not, select Add device > Bluetooth and pair it again.
If Bluetooth shows as off or stuck (slider greyed out)
- Turn Bluetooth off and on from Settings even if it appears on:
  1. Go to Start > Settings > Bluetooth & devices.
  2. Turn Bluetooth off, wait at least 10 seconds, then turn it on again.
  3. Try using or re‑pairing the Arc Mouse.
- Restart the Surface Pro to refresh Bluetooth drivers and services:
  1. Select Start > Power > Restart.
  2. After restart, check Bluetooth & devices again and test the mouse.
Remove and re‑pair the Arc Mouse
- In Start > Settings > Bluetooth & devices, find the Arc Mouse in the list.
- Remove it from the list of devices.
- Press and hold the mouse pairing button for 5–7 seconds until the light blinks.
- Select Add device > Bluetooth, choose the Arc Mouse, and complete pairing.
Check for Windows and driver updates
- Go to Start > Settings > Windows Update.
- Select Check for updates and install all available updates.
- Restart when prompted and test Bluetooth and the mouse again.
Rule out interference or device‑specific issues
- Temporarily turn off other Bluetooth devices connected to the Surface Pro and see if the Arc Mouse stays connected.
- If possible, test the Arc Mouse with another PC. If it works there, focus on Bluetooth configuration on the Surface Pro; if it does not, the mouse may be faulty.

If the Bluetooth toggle continues to appear greyed out or off after these steps, follow the broader Bluetooth troubleshooting guidance in Windows, including the automated troubleshooter, from the referenced articles.
