Question about Texas Instruments TI-84 Plus Calculator

Problems with TI - 84 plus

For no reason whenever I press a button the calculator takes some time (10-20 seconds) to carry out the command or respond.
The amount of time varies with the buttons, and some buttons don't work at all (or the calculator just doesn't do anything).
I have replaced the four AAA's and the SR44SW cell, but it has made no difference. Also, sometimes when you turn it on it comes up with the words "RAM Cleared." Any suggestions? I bought it from Calcutronics an ebay seller so it isn't new but hopefully still under warranty.

    My T1-84 is acting up. When I turn it on, it says RAM CLEARED. It takes about 10 seconds of pressing on any button for it to take. I've replaced the batteries but still won't work. Help?

    No I still haven't found a solution, hopefully a replacement is on its way,but I haven't heard from Calcutronics as yet. Good luck!

  • jaygees1 Apr 18, 2008

    Yep tried all of the above . It comes on for a second then says replace batteries and turns off. The next time it comes on , its back with the ram cleared message......go figure...........have been on the TI website and tried their suggestions but no luck.

    I had the problem but thanks Kit1094 your solution fixed it.

  • Becca Hammer Oct 07, 2008

    that was the same exact thing that happened to me but if you do blow in the I/O thing it fixes it but for me it only worked for 10 secs

  • Anonymous Oct 10, 2008

    I had the same problem. Tried everything deleting memory, programs, resetting everything. Reloaded OS, tried everything. Then saw this solution for blowing in the I/O port and I thought no way but give it a try anyway.. Blew it out and now it works great.. Thanks for sharing!

I actually fixed mine!!!! The same thing happened to me. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard (you may want to use compressed air, but I didn't have any onhand), and it works perfectly now!!!!!!!!!! I hope this helps.

I cant figure out how to be able to take a fraction and subtract it to another fraction on my TI-84 PLUS calculator

Given two fractions a over b and c over d, you can subtract the first from the second by entering
( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER

My TI-84 plus silver edition calculator is not responding. Whenever I press a button it takes forever to put it up on the screen or it doesn't work at all! I need some serious help with this. I tried...

Hi purzabumafu8,

You need to re-install the Ti 84 Plus OS on both calculators, ASAP!!! You can fix these problems by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the USB or, IO link ports. Then they can send you a copy of their OS, while you receive it on your Ti 84 Plus. Hopefully, your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work. Link the two calculator together through the USB or, IO link ports with the proper cable. If don't have another reliable calculator to connect too, you'll have to connect the calculator to a computer to download the OS, goto Procedure 5. If your downloading off another calculator goto Procedure 1.

Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.

Procedure1. Procedure to linking to another calculator.
On their calculator press, [2nd][Link][G] [Right-Arrow]. On your calculator press, [2nd] [Link] [Right-Arrow] [Enter] and, then press [ENTER] on their calculator too. Their calculator should say, "TRANSMIT" and, your's will say "Receiving." Then on both calculators once transfer is complete press, [2nd][MODE] to quit and, return to the Home screen. If the OS was transferred then your finished with these procedures. If your calculator won't turn on or, is locked up try the Procedure 2, below.

Procedure 2.

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
"Waiting...Please install calculator software now". If calculator did not turn on or, is still locked up goto Procedure 3, unless already did Procedure 3, then goto Procedure 4. If you calculator does come on and is responding and, your connect to another calculator goto Procedure 1. If you calculator does come on and is responding and, your connect to a computer goto Procedure 7.

Procedure 3.

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. Goto Procedure 2.

Procedure 4.

If the above process did not work. Try re-doing the Procedure 2, and, this time extend the time in Procedure 3, by 5 minutes to 10 minutes before you put all the batteries back in the calculator. These calculators can be a little stubborn at times so, keep trying Procedure 2.

Procedure 5.

If you can't find a calculator to connect too, you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS.
Procedure 6. Procedure to installing the latest Ti84 Plus 2.55v. MP OS. TI OSDownloader does not always install the latest OS.
You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.
Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed. If your calculator will not turn on or, is locked up goto Procedure 2. Or else goto Procedure 7.

Procedure 7.
Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.
Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install. Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.
If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.

I have a TI-84 plus silver edition. there was a notice on my screen saying that batteries were low. I replaced them, and when I turned it back on, the RAM was cleared, but the screen acted like it was...

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 that isn't it, then remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries and turn the calculator on. (You may have to adjust the contrast as described above.)

Where is the equal sign on the ti 84 plus

hello sir, Press "second" "math", and it should be the first thing listed. If you need other commands hit "second" "0" that will enter the catalog and you can press any letter (without hitting alpha) to jump to that letter in the list.

My TI-84 Plus Silver Edition stopped working

That actually is a result of water damage. You probably need to replace it, or see about getting it taken apart and dried if the water damage was recent. DO NOT take it apart yourself. Go somewhere and ask if that is possible.

sounds like your backup battery is dead.. and maybe the clear or del key stuck down as either way it could wipe the program.. The solution i think is to hit the TI website and get the software reload and directions to reload it from there.

My TI-84 Plus always turns off randomly

Try resetting the calculator to what I will call the "factory settings", do so by holding the "CLEAR" button, and while holding it, take out the batteries, then put them in
