Solved Why Wont My Ti84 Plus Ce Turn On At All Ti 84 Plus Ce
Chosen Solution The calculator is plugged in and the light on the side is glowing orange, but the screen is black like it is off and doesnt change whatsoever Hmm, hopefully the answer is just you need to plug the cable into the USB port harder, or try a different cable. Can you try a different power source? ie instead of using the charger brick that came with the calculator, plug it into your laptop (or vice versa)....
