My calculator is not turning on. I have bought new battery and it is still not working. can you please tell me what i should do? i have a TI-83Plus

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.


If this doesn't do it, reply to this post and we'll go on to the next step.

The 86 has more memory. It also has some advanced calculus capabilities the 83 doesn't. However you're much more likely to see examples for the 83 in textbooks and other references.

Good Luck and please rate 4 thumbs up for the free answer

I am inserting a copy of an earlier post to a question similar to yours. Ignore the steps you already tried. I will add a few comments at the end just for you case. Please read the post till the end.

A Try this before thinking of repairs.

1. Push the ON button.
   
2. Even if you see nothing, press the [2nd] key and release it.
3. Press and HOLD the UpArrow key until the screen darkens.
4. You may have to keep pressing UpArrow for a little while before you see anything.

B If that does not work

1. Remove one of the AAA batteries.
   
2. Press and hold the [CLEAR] key.
   
3. While holding [CLEAR], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. The calculator should display the message "RAM Cleared".
   
6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".

C. Third option

1. Remove batteries including the backup battery for 5minutes.
   
2. After the 5 minute period, reinsert all of the batteries and
   
3. turn the calculator on.
   
4. Adjust the contrast if necessary.

D. Last option

The last option requires the reinstallation of the system. So to use it you must download the TIConnect 1.6 software from education.ti.com. You must have the TI USB SilverLink or the TI Black serial cable ready.You must be connected to the Internet.

1. Remove one of the AAA batteries.
   
2. Press and hold the [DEL] key.
   
3. While holding [DEL], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. The calculator should display "Waiting...Please install calculator software now".
6. Connect the TI Connectivity cable between the computer and the calculator.
7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OS Downloader.
8. Follow the on-screen directions to reinstall the calculator's OS.

If the message "Error! Press any key to turn unit off. Then turn unit back on." appears on the graphing calculator, quickly, remove one battery from the calculator and reinstall it while the transfer is taking place.

You have several ways to connect the calculator

• Serial Black cable that used to ship with the TI 83 Plus. It connects to a serial port on a computer and to the I/O port on the calculator. It requires the Graph Link software available on the TI web site (Downloads, Software and Apps, Connectivity)
• USB Silver Link cable. It connects a USB port on the computer to the the I/O port on the calculator. It requires the TI connectivity software, also available on the TI Web site.
  
• A USB mini A to mini B cable to connect two units.
• An I/O cable to connect two calculators through their I/O ports.

If you do not have any type of USB cable (SilverLink, Mini A/B to Standard USB) you cannot use the USB option. You can however try to connect your calculator to a similar one through the I/O ports. If you have the I/O cable you can transfer the OS of a working calculator.

Another solution is to buy the accessory cables from the TI Online store. The I/O cable is not very expensive ( about 5 $) and the TI silver Link about 25 $. If you are a student, ask fellow students who have other types of TI calculators (TI 83Plus, Ti84 Plus, Voyage 200 PLT, TI 92/92 Plus) to lend you their TI Silver Link cable. Ask your teacher.

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 at all. 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.

i found this somewhere else on this website
and it worked for my broken ti-83plus which had same odd startup symptoms.

Remove one of the AAA batteries.
Press and hold CLEAR while reinstalling the AAA battery.
Continue holding CLEAR button and press ON.
Release buttons and press CLEAR again.
Calculator should be normal mode now. ;0)

Firstly check the battery compartment for any sign that the old batteries have leaked. Look for signs of corrosion, white powdery deposits on any of the contacts? You can clean the contacts with a little alcohol or a light abrasive. Also check they are in the correct way round!! Next you can reset the calculator as described on page 740 of the manual which you can download below: http://education.ti.com/guidebooks/graphing/83p/83m$book-eng.pdf The full reset of the calculator is as per this diagram:
