Hi Scott Hughes1,
Thank you for reaching Microsoft Community. I understand that you're having trouble connecting your Surface Mouse to your Surface Laptop. Let's work together to resolve this issue.
Before we proceed, I would like to confirm. Is this the mouse that you have: Buy Surface Mobile Mouse – Microsoft Surface?
Is this the first time that you are trying to connect or pair the mouse to a device, or this used to work before and suddenly issue occurs?
If you press and hold the pairing button at the bottom of the mouse for 5 seconds, does the LED light starts to flash?
How about other Bluetooth accessories, are you able to connect or pair them to your Surface? This is for us to isolate if the issue is with the mouse or the Surface itself.
To troubleshoot, first let's check if your Surface Laptop has Bluetooth turned on. To do this, follow these steps:
- Go to Start menu and click on Settings.
- Click on Devices.
- Click on Bluetooth & other devices.
- Make sure that Bluetooth is turned on.
If Bluetooth is turned on and you're still unable to connect your Surface Mouse, let's try resetting the mouse. Here's how:
- Press and hold the pairing button on the bottom of the mouse for 5-7 seconds until the light on the bottom of the mouse starts flashing.
- On your Surface Laptop, go to Start menu and click on Settings.
- Click on Devices.
- Click on Bluetooth & other devices.
- Click on Add Bluetooth or other device.
- Select Bluetooth.
- Select Surface Mouse from the list of available devices.
- Follow the on-screen instructions to complete the pairing process.
Here is an article also that you can check for more details in setting up the Surafce Mobile Mouse: Set up Surface Mobile Mouse or Microsoft Modern Mobile Mouse - Microsoft Support
Let me know how it goes.
