A:AnswerHello John, Yes, you can use the Bluetooth in your laptop to use with the M650 L. Here's a link to the Getting Started PDF that will walk you through the setup: https://support.logi.com/hc/en-us/articles/4414458320663-Getting-Started-Signature-650L. - Richard from Logitech
A:AnswerNO, it only works with the Bolt receiver which is newer and different signaling than the Unifying receiver. Two different technologies and they will not "cross" connect with each other. If you look at the back of this mouse it has a little Lightening Bolt insignia on it.
A:AnswerHello David! The Signature M650 Wireless Scroll Mouse with Silent Clicks doesn't have the multi-device Easy-Switch feature no. If you're in the market for a mouse that offers this options, I would suggest checking the M720 Triathlon, the MX Anywhere 3 or the MX Master 3S mice. - Mathieu from Logitech
