    My TI_84 silver edition is very slow. It takes forever for the characters to show on the Lcd. What is the solution?

    Thanks a lot

    I have to hold down the key for 3-4 seconds before the calculator responds

  • jparker671 Jul 16, 2008

    Same Problem. I have removed and replaced batteries, but I cannot remove the back up battery. How do you do it?

  • rda889 Sep 04, 2008

    I had the same problem, replaced the batteries (both types) and still didn't work. i went to the TI website here and found some info:



    http://epsstore.ti.com/OA_HTML/cskmbasic...



    It said that the slow key response could be due to a short in the I/O socket. I blew into it really hard, and it worked perfectly after that. I hope this helps. There is more trouble shooting info at the link above.

    all i did was take some compressed air and blow it into the I/O slot and now it works like a charm

    THANKS WHOEVER THOUGHT OF IT!!!!!!!!!!!!!!!!!!!!!!!!!!!


  • edgineer Sep 06, 2008

    We had the same problem with our new TI-84. The calculator was very slow to respond to key presses. I blew some compressed air into the I/O connector and now IT WORKS!!!! Thanks everyone.

  • Anonymous Feb 06, 2009

    Thank you so much. I'm a high school math teacher and I have had this problem with one of my calculators since we bought them. We called tech support and spend hours with them, but they were no help. But your solution worked and I'm SOOOOOOOOOOO HAPPY!!!

  • guillotine73 Mar 03, 2009

    I blow in the i/o socket, but it didn't work. I try blowing it really really hard, and it still didn't work.

    Any solutions, please help

  • ShinTwo Mar 28, 2009

    My TI 84 Plus Silver edition won't turn on. The blinking square that appears when you turn it on is very light. It is brand new, I have used it only three times. At first I thought it was the batteries, but after I put in the new batteries it still doesn't work. The screen appears very light.

Had the super-slow unresponsive problem. Held CLEAR button down: no change. Removed all batteries, reset memory: still didn't work. Reloaded the O/S: same thing. Blew into the hole: FIXED! Unbelievable! THX!

  • bendo33 Jan 21, 2011

    I tried everything! Looked on TI's website, followed instructions to reset, took out backup battery, nothing worked. BUT lo and behold! Upon reading the miracles that happened after blowing the I/O port did, naturally I did the same. And what do you know, it worked!! Haha I also took off the faceplate and blew into the rectangular crevices for good measure!

Believe it or not, but the compressed air solution worked. Before trying compress air, I tried several things. I changed batteries, including the backup battery. I tried the DEL and CLEAR solution. I reinstalled its OS. I reset the calculator. I deleted the GARBAGE file, but the only thing that remotely worked was the compress air. Thank you!!

Posted on Sep 10, 2012

Haha, I didn't think blowing into the I/O socket thing would work, but it totally did!!!! Thanks for everything who ever solved the problem.

  • ayin142 Apr 06, 2011

    I can't believe this as well! You gotta get the straw part into the hole and use compressed air to blow hard on the I/O hole. I can't believe this. My calculator has not worked for YEARS and just after following that instruction here, it works! =D THANK YOU SO MUCH!

It sounds like the calculator's flash ram is expired or faulty. When a particular bit in the flash is accessed more than an arbitrary number of times, it will no longer be able to accessed. the best solution is just to replace the calculator, you can find some real good priced used ones on ebay or www.usedcalculators.com

The TI website suggests (if all other things above didn't work) taking all the batteries out, even the backup batt. and leaving the unit empty for 5-10 min. Then reinstall batteries. This should return unit to factory settings.

If you just got it new then you should return it for an exchange or refund.

If it's a little older, it may be a bit too full (think of your computer running too many things, get's really bogged down.)
You can reset it by
2nd>mem(+ sign)>reset>ram(menu)>yes
or just go from factory defaults by
2nd>mem>reset>right 2x(ALL at the top of screen)>yes

if that doesn't work then I would suggest going to the TI website and getting the newest OS for your calc and installing that through TIconnect software.

Good Luck

The calculator writes 8 all over


During operation of the TI-Nspire handheld it may be necessary to reset the device. Circumstances which may require a reset include; keys not responding, device will not turn on or a garbled display. To reset the device:
• Remove the keypad (for TI-Nspire with ClickPad, TI-Nspire with TouchPad, and TI-Nspire CAS with Touchpad) or the battery door (for TI-Nspire CAS with ClickPad) and remove at least one battery from each column of batteries. After 2-5 seconds, reinsert the batteries but do not turn the handheld on.
For the TI-Nspire and TI-Nspire CAS handheld units with ClickPad:
• Hold down [home] [enter] [P].
• While holding these keys press [on].
For the TI-Nspire and TI-Nspire CAS handheld units with TouchPad and the TI-Nspire CX and TI-Nspire CX CAS:
• Hold down [doc] [enter] [EE].
• While holding these keys press [on].
Please Note: For TI-Nspire Family handheld units that contain rechargeable batteries you can alternatively hold the above keys while pressing the [reset] button on the back of the handheld rather than removing the battery for 2-5 seconds.
• The device will boot up as in the previous reset, but will display a menu with the following options. Please try options 2, 3, and 4 in that order.
• 1: Cancel - The most non-intrusive reset option; no changes are made, the unit restarts.
• 2: Delete Operating System - The operating system will be deleted without deleting any documents on the system.
• 3: Delete Document Folder Contents - This will delete the user's documents, but will not delete the OS. Selecting this option is the same as using the RESET hole on the back of the unit.
• 4: Complete Format - This will delete the OS and all documents for a total wipe of the handheld.
Please note that the second and fourth option will require that the OS will need to be reinstalled

Repair ti 84 plus silver edition


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. Does it?

How do you put the batteries in?


  1. Remove the keypad (for TI-Nspire) or the battery door (for TI-Nspire CAS) and remove at least 1 battery from each column of batteries. After 2-5 seconds, reinsert the batteries and turn the unit on. This will cause the unit to reboot the operating system.
  2. Remove the keypad (for TI-Nspire Family or TI-Nspire CAS Touchpad) or the battery door (for TI-Nspire CAS) and remove at least 1 battery from each column of batteries. After 2-5 seconds, reinsert the batteries and LEAVE THE UNIT OFF (do not turn on and then back off). If the TI-Nspire/TI-Nspire CAS is a Clickpad, hold down [Home] [Enter] [P], and while holding these keys, press [On]. If the TI-Nspire/TI-Nspire CAS is a Touchpad, instead hold down [Doc] [Enter] [EE], and while holding these keys, press [On]. The device will boot up as in the previous reset, but will display a menu with the following options. Please try options 1, 2, 3, and 4 in that order. ** The [Home] key is located at the top right of the TI-Nspire keypad and has a picture of a house on it.

I have a ti 84 plus silver edition calculator and the screen went black. how do i fix this


There are two possibilities:

1) Your screen may have been physically damaged. This is not repairable.

2) The second possibility is the screen contrast is turned too high. You can adjust the screen contrast by pressing either 2nd and then the up and down keys or Alpha and the up and down keys, depending on your model. You will need to do this repeatedly to notice a change.
