Thank you for letting me know.
Since it’s a new laptop and you’re connecting the mouse directly via Bluetooth, let’s try a few quick checks:
- Open Settings > Bluetooth & devices and make sure Bluetooth is turned on.
- Put your mouse in pairing mode (usually by holding down the power or connect button until the light blinks).
- Select Add device > Bluetooth, then wait for the mouse to appear and try connecting.
If issue persists please try "Fix Bluetooth problems in Windows" https://support.microsoft.com/windows/fix-bluetooth-problems-in-windows-723e092f-03fa-858b-5c80-131ec3fba75c
Let me know how it goes or if you have any further questions or concerns.
