My new TI-84 Plus Silver Edition will not turn on most of the time...only on certain occasions. I have put brand new batteries in it. Is there a way I can reset it to turn it on or is it simply a defective calculator?
TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on.

If you're willing to lose all the contents of memory, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does the calculator now turn on normally (you may have to adjust the screen as described earlier)?If you're willing to lose all the contents of memory, remove all four AAA batteries.

If this item is new I would return it, from what you have said the Graphic Calculator has had microprocessor ic failure and there is nothing you can do but return it.
Hello, The most likely reason is that the backup battery is drained. Change the backup battery. When you get the Ram Cleared message, just press [CLEAR] to erase the message and start using the calculator. Hope it helps.
You may need to reset calculator. Take ou the batteries and the backup battery. Leave them out for about 8 hours. Then put everything back in. Hopefully this will work.

No, that did not work either.

That didn't change anything either.
