Are you teaching in a tech classroom? Frustrated by the powerpoint remote not working? To check if the batteries (2 AAA’s) are the problem, pull the little receiver out of the hand held device and press the laser button on top of the remote. If the light comes on, then the batteries are fine. If the light does not come on, the batteries are dead and need to be replaced.
Is the red light laser pointer working but your slides are just not advancing? the batteries are fine, but you may have it plugged into a port that is not working with the receiver. Try one of the USB ports that is on the front of the computer, or the USB port that is on the back of the keyboard. See the picture above. Do Not plug the remote receiver into the monitor. See the picture above.
