Mouse without dongle won't pair
I have a Dell Latitude E7440 laptop that supposedly supports a bluetooth mouse without a dongle. I've tried two different mice that don't require a dongle, but neither would show up in the pairing list. I do know how to pair bluetooth devices, but never had this problem where the device doesn't show up in the pairing list. I'm currently using a mouse with a dongle, but I'd like to free up the usb port. Any ideas?

What version of Bluetooth does the mouse require? This is a relatively old system and if the mouse needs a newer level of bluetooth support, you may need to upgrade the bluetooth (or wifi/bluetooth) adapter in the system.

@ejn63 This is a refurbished laptop. Using Bluetooth Version Finder V1.5 app, I found Dell Wireless Bluetooth Device is version 4.0, which is the same as the mice I tried. When checking the version, another item showed up: "Dell wireless 375 Bluetooth module version 3.0", but I'm not sure what that is.

Additional info. Refurbished laptop running Windows 10 Pro. Bluetooth version 4.1. One of the mice I tried was a Logitech M240. I returned the other mouse, so not sure what model that was. I know it was a generic dongleless mouse.
