I had the same problem nothing worked after raplacing the batteries. The problem with me was dirt/dust in the IO-port, I put the nozzle of the vacuumcleaner on IO-port and turned the cleaner on for a few seconds. After that the calculator worked like a charm.

7 letter word with the letters a u f n h c u e h c a u d w

very good
you give a list of letters that you want to use in a maths class
I would have thought that with letters , the class would have been a english class and numbers for a maths class
or maybe you are doing the theory of probability and want to know how many words could be made from those letters

My TI-83 PLUS wont turn on

Remove one battery from the calculator and then press and hold down the CLEAR key while re-installing the battery. While continuing to hold down the CLEAR key, press and hold down the ON key. If this doesn't work, then hold DEL and then ON. If unsuccessful, remove all the batteries, including the lithium watch battery, and leave the calculator like that for a while.

This is documented in the TI-83 Plus Guidebook, but unfortunately, not many people know about it.

If that doesn't work, send it to TI for repair. They probably won't even charge you!

I am getting the wrong results when performing some basic FV math problems. Doy you have any math problems that would help test my calculator?

It might be more efficient to make the calculator perform a self-test. Here is the procedure.

Verifying Proper Operation (Self-Tests)

If it appears that the calculator will not turn on or otherwise is not operating properly, use one of the following procedures.

1. With the calculator off, hold down the [ON] key and press [X] (the multiply key)..
2. Release the [ON] key, then release the [X] key. This initiates a complete test of the calculator’s electronic circuitry. If everything is working correctly, within about 25 seconds (during which the word RUNNING the display should show –8,8,8,8,8,8,8,8,8,8, and all of the status indicators (except the * battery power indicator) should turn on. If the display shows Error 9, goes blank, or otherwise does not show the proper result, the calculator requires service.

Tests of the calculator’s electronics are also performed if the [+] key or the [divide] key is held down when [ON] is released. These tests are included in the calculator to be used in verifying that it is operating properly during manufacturing and service.

If you had suspected that the calculator was not working properly but the proper display was obtained in step 2, it is likely that you made an error in operating the calculator. We suggest you reread the section in this handbook applicable to your calculation — including, if appropriate, appendix A.

Here are some examples from the manual (there is overlapping in the first two screen captures)

About the only other solution I can think of is to take out the backup battery if you haven't already done so. Might work.
