A:AnswerI'd suggest you get into contact with whatever company you sent your laptop to for service, or contact Logitech. I haven't had this happen but it would really suck to have to spend that money again for just the dongle.
A:AnswerHi Idpmail, you are correct! The only difference between the two is the mouse option with the MK270 Combo. Since it's the holidays, it's very possible that the combo is less expensive right now. So snag it so you can save some money! Hope that helps! -N from Logitech
