SOURCE: Find the antilog on the TI-84 Plus for finding pH in chemistry problems

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

SOURCE: water damage on TI 84

try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .

it sounds crazy .

Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
.

Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.

Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.

It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).

beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.

This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.

TI 84 Plus had some water damage. Calculator works except for certain keys (0, ., (-) and enter. Any ideas?

If you're adventurous:
note the location of the non-working keys
take the batteries out
unscrew all screws from the back of the calculator
pull top and bottom halves apart (do this carefully so you don't break something) and hold calculator so keys and screen are down.
check for corrosion under non-working keys, it'll be a different color of metal on circuit board under keys
if you find corrosion use steel wool or some other mildly abrasive device to gently remove
reassemble calculator

I suppose they can be replaced. You should contact the TI Consumer Support Department at [email protected]. They will be able to tell you where in your area of residence you can have the calculators serviced and how much It will cost you.

I have heard about a Casio program that gives credit towards the purchase of Casio calculators in exchange of TI calculators. Here is the link to the trade-in program.
I believe it is worth investigating this. You may end up replacing the calculators at a lower price. Casio calculators are very good and less expensive than the TI. You will be surprised to hear that Casio is the inventor of the LCD screen.
