Coffee spill in calculator

Hi, I spilled coffee in a new Sharp desktop calculator this morning. Is there anything I can do to revive it. I have turned it upside down, sprayed it with the canned air and left it unplugged to dry. Is it hopeless?

Re: coffee spill in calculator

I've wetted a wide variety of gadgets, and I've found that generally- not always mind you- leave it to dry for a few days, it could come right on. DO NOT plug in the machine until you're certain there's no remaining liquid inside, and when you plug it in do so at your own risk; be aware that some conductive mineral in your coffee might have been deposited inside, across a circuit and short the whole thing. A short may result in fire. You can make the process alot safer by plugging into a GFCI outlet (one of the ones with the breaker built in, like in a kitchen). I've had calculators and phones, cellphones, a playstation and even a network card survive a drop into water (and other liquids >

Sharp EL-1197PIII Calculator won't print using the blank ink. Ribbon is correctly installed.

I still have to believe that your ribbon is not quite seated properly on this. I would check that again. If this is not a "cartridge" then Check to see if it is upside down.

The screen on my calculator is upside down how do I turn it back?

The calculator may have been subjected to a hacking procedure from the Internet. Try to find an antidote (on the Internet) or buy another calculator. You can also enter your calculation without looking at the screen, and when a result is found turn the calculator upside down to read the result.

Soda was spilled on sharp el1179p

do not power on the device, it is crucial that you leave it to dry and as soon as possible put it in a bag of rice. The rice will absorb the moisture in the device. You should give it about two weeks (the longer the better) and you should have completely removed all battery components at this point if there are any. After a generous waiting period of two weeks or so, take it out of the rice and give it a try. I spilled a full 8 oz cup of hot coffee RIGHT into my laptop keyboard and it immediately shut off but I followed the above steps and I am using it right now just fine and it is a year later. Good luck!

Coffee was spilled on the calculator. How can it be fixed?

I am not sure if you will depends on how much water coffee reached the motherboard inside. Sometimes you can open them up with a screwdriver and let it air out for 24hrs and then try. If after 24hrs it doesn't come back on you might have to get another one. It truely depends on if anything shortened out.

Graphing calculator got coffee spilled on it

Your only hope is to open the case and wash out all the coffee with plain water. Don't forget to clean all the keys and switches under them. Dry and reassemble. This is a last chance procedure and may fail.
Don't spill liquids on electronic gadgets as the result is either much work or must replace.

Sharp calculator

I had the same problem happen to me. What I did was carefully take the calculator apart using a T-10 Torx screwdriver to remove the back cover. I then used a compressed air can and blew air into all the crevices and holes in the calculator. I was able to dry almost all of the soda the spilled, however some of the soda dried and turned into somewhat of a sticky mess. I was able to carefully wipe the sticky parts clean with a tissue. After doing all of that my calculator worked perfect.

My Ti83 silver edition will not turn on.

I'm not sure if this will help you patchesb7; it sounds like your calculator is having issues :(
This will help others whose calculators suddenly won't turn on anymore, even after changing the batteries.

This will return the calculator to the way it was when you got it out of the package. Any data or programs have stored since will be lost.

Step 1: Remove all four AAA batteries.

Note: You will have to hold down the CLEAR button while doing Steps 2 and 3. Do not let go until after you have pushed ON in Step 3. I found this easiest to do by holding the calculator upside in my left hand with my pointer finger holding the CLEAR button so the ON button was easier to access.

Step 2: Hold down the CLEAR button (located under the arrow keys) and reinstall the AAA batteries.

Step 3: Press ON button and then let go of both buttons. The screen should say the RAM has been cleared. Press CLEAR to continue.

Don't know what model of Sharp you have but most sharps you can take keyboard apart and clean the rubber keypad magnets and the mylar circuit with warm water. let dry and reinstall. Check to see if Coke did not get in other parts. Do not use anything strong such as thinner. Rubbing alschol is good because it evaporates. Good luck
