Calculator won't turn on

"You should probably refer to this guide. ;)

As for the reset button, there is none on the regular TI 84 Plus. You need to remove one of the AAA batteries, then remove the backup battery. Hold [ON] for 10 seconds then reinsert the batteries. This should clear your RAM. You can also refer to this video if you would like a video representation of the guide."

Take out the AAA batteries.Hold the on button for 10-20 secondsPut the batteries back inPress the on button againThen it should come back on as “RAM CLEARED”.
