That is asking too much. The calculator is not supposed to take a bath no matter how short. Try to have it repaired, if at all, but do not expect that to be free of charge.

SOURCE: TI-83 screen is black

The "color" on your screen reset to dark. You can adjust it by pressing "2nd" and the "up" arrow (or "2nd" and "down" arrow) repeatedly.

SOURCE: Horizontal lines obstructing the second half of the ti 83 calculator screen, anyone know repair tips?

I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.

Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.

SOURCE: I downgraded my TI-Nspire's OS

I had this same problem myself and I had to look everywhere to find a solution. You will have to remove the current OS from your device. Heres how.

http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=101985&nUsePub=NO&jttst0=6_23871,23871,-1,0,&jtfm0=&etfm1=&jfn=ZGC81E19298A9321E38D51491551F331C8CCDA6801E50CC672F84B3EFDF0F6ACEF9DD42026E6C2FF1F9579670CF87CEAF79D

I couldnt use option 2 for some reason and had to use option 4 (complete format, luckily I had backed the files up earlier) but once it was reformatted the device showed up in the software and told me to update the OS. From here you just install the latest OS as you would normally.
The problem with what you and I did is that previous OS versions (1.7 in my case) dont support the keypad, you may be able to use the older version with a different keypad but I'm not sure.
Anyway, I hope you can fix it, good luck.

My TI-nspire cx cas calculator says operating system not found. Install OS now. Can someone fix this problem?


Have the TiNspire Computer Link installed on your computer.
Download the OS from from education.ti.com
Connect your calculator to the computer with TINspire Computer Link. Run the software. It opens an explore type window. Under the TOOLS tab find Install OS. If it does not connect to the Internet, point the software to where you stored the downloaded OS.

My Calculator is saying operating system not found. Install OS now. How do I install Os?


To transfer the operating system to the handheld, connect your handheld and computer with a USB Connection Cable and use TI-Nspire™ Teacher Software with TI-SmartView™ or TI?Nspire CX Student Software (Windows® / Mac®).
This is the link that will download the OS (it's free) to your computer:

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

How to get the ti nspire cx to give square root answers


You can not achieve this with the Ti-nspire cx. Only the CAS version will give the square root form. On the CAS there is an option in the settings called "EXACT" under calculation mode. The cx does not have this mode.

Hi, I have a problem with ti-nspire cx cas.


The Ti Nspire CX CAS has a built in battery. It must be recharged. If you plug it in a wall socket or in a USB charger you should be able to use while it is being recharged.

Im getting the wrong answer for when i try to solve for a trig inverse on the ti nspire cx


When you are dealing with trigonometric functions and their inverses, the results depend on the angle unit (degree, Radian, Gradian).
To set the correct angle unit (the one required by your problem)
  1. Turn calculator ON
  2. Press Menu key.
  3. Press 5:Settings>2:Settings>1:General
  4. On the second line Angle, there is a drop-down menu you activate by pressing the Right Arrow.
  5. Select Degree, Radian or Gradian and press Enter.
  6. Using the down Arrow move focus to the bottom of the screen where you can Make Default, or OK.
  7. Press one or the other.
  8. Validate your selection if asked.
