This is going to sound super dumb put leave it in a bowl of rice for a couple days. Rice will obsorbe the water. Also, change all five of the batteries(the 4 AAA ones and the back up battery). And if that doesn't work, you're pretty much out of luck. However, don't rush to the store and buy a new calculator. If you're in college or know someone that is in college, do what I do. Go to a math or sicence lab professor and ask them for a calculator at the end of the semester. I'm getting a new 89 pretty soon and i'm kinda excited. Good luck with your calculator

Ti 84 water damage


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.

Unzip it. Transfer it to a Secure Digital card, then plug the card in the SD-card slot. Use the File Manager/explorer and move the library to the Memory location you want.

Ti-84 Silver Edition received water damage and cant be switched on


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.

I don't even know!


What i think is that your calculator has water damage. It is not dead. There still is hope. The slow response is due may be due to a short in your I/O port. Blow really hard in there that might stop the slow response. Other than that let it sit without the batteries to dry. Then put the batteries back in and if that doesn't work its probably what spongeboob said and your going to need to ditch it.

Lag + Doesn't shut off... (ti84plus)


the I/O plot matters. If blowing doesn't help, insert a stick or something into it. I had the same problem, and my TI 84 plus had already been extremely unresponsive and slow before, as I fixed the latter problem by blowing really hard into the I/O plot, I did the same to fix the new problem. For many times nothing happened. Then I insert a metal stick into it and gently hit it inside. In a short while, the calc was normal again!! Now my calc even turns on when it's been put off, with its cursor frozen. I simply use my little finger to dig/scratch the plot and see the lovely cursor beating again. PS Having such a funny calc is really bad, but every time you fix it you'll feel good

None of my buttons work except the ON button


Sounds like a possible short to me, But I don't have experience with that cause I have yet to test my calc with water if you know what I mean... The one thing that I can suggest is trying to connect with another persons calc and try the "send OS" command to see if that will reset your calc to a working state. Sorry to hear about the damage though.

Screen is half Black


The ribbon cable that controls the screen is damaged (or the liquid crystal has baked out... tis happens when the unit is exposed to high temps or long periods of direct sunlight). From my experience w/ these calculators they cannot be repaired.
