Sir I have bought this Logitech combo, I have left the dongle to the laptop and kept in the bag . It was bent slightly and it was not connecting What should I do sir.
Try to reset your driver or change the battery of your keyboard/mouse and see if it's working. Otherwise, order another one, and baki tho aap samjhdar ho ge hi :)
