No power with new batteries


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.

Ok, so i replaced the batteries in the calculator.. And now it wont even turn on. Brand new batteries and everything, Any suggestions?


Hey this sounds like the classic contrast problem.
But first make sure that the batteries are good and that they are installed with the proper terminals alligned correctly
Second, and this is the classic problem, turn on the calculator and then press second and up. The screen should begin to darken and you should begin to see the cursor.
If you go to far or in the even that the screen is dark, lower the contrans by pressing second, 2nd, and then holding down.

Hope this helps
Happy Calculating

TI-89 won't turn on, even w/ new batteries


Try a hard reset:

Press and hold the 2ND, Left, and Right keys.
Press and release the ON key.

Be aware that this will clear all RAM.

Won't turn on


Most likely nothing is broken at all. 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.
