It has a solar battery. It has to be in the light, either sun light or artificial light to operate. HOWEVER, if the battery is shot, it must be replaced. Take your calculator to any radio shack store and ask them to test the battery for you. If it is no good, they will be able to replace it for a fee.

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

Press [2nd] [LOG] to display the menu for logs and exponential functions. Select [LN]. Enter the (positive) number, close the right parenthesis and press [ENTER].

### It just won't work with the 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.

### Our t84 won't hold any battery life. we have changed both the lithium and the tripl a's and you can only use the calculator one and then its out of battery......what is going on?

Possibility: Some third-Party programs (games essentially) are installed on the calculator. They may be ill-designed and circumvent/turn OFF the Power saving features of the calcuator.Also, Texas Instruments recommends to use alkaline (non-rechargeable) batteries only.

### No display at all, does not seem to be turning on, yes I replaced the batteries.....any thoughts?

Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

### My TI83 won't turn on. I just put in new batteries

Having gone over a month without a response to my query, I assume my suggestion to change the screen contrast solved the problem.

### New batteries and won't turn on

You might want to check the batteries, and make sure that they're in the correct way. If they are, then you either purchased bad batteries, or your 83 suffered a catastrophic failure/broke

### It's "frozen". won't change from the screen its

Try to reset it by taking out the batteries and leaving to sit for a minute or so, if that doesn't work take out the small battery as well and leave it sit, if you're still stuck you can call ti-cares (800-842-2737) they're generally very helpful.
