SOURCE: My TI-89 Calculator will not turn on.

The damage was battery corrosion. If you CAREFULLY take a damp(not dripping wet) rag and wipe the contacts of the corrosion you may have luck. The batteries just leaked, Very common especially for cheap "Heavy Duty" batteries. Alkalines seem to hold up better in a discharged condition. I hope this helps.Do wash your hands after the cleaning. A q-tip may also be of help. Just wet it and squeeze most of the water from it.

Hello,
You should ( a suggestion) reset the OS by pressing the button on the back of the unit.

If that does not work, you may consider reinstalling the OS. The procedure as described in the TI Knowledge Base is as follows.

What steps are required to reinstall the TI-Nspire family operating system?

To reload the device’s OS using a computer with TI-Nspire Computer Link:
• Connect the TI-Nspire device (with the Nspire keypad) to the computer using the USB Standard A to Mini B cable.
• Open the TI-Nspire Computer Link software. The select device dialog should appear, and detect the device.
• Either drag the OS file (available in the ‘downloads’ area at education.ti.com) onto the TI-Nspire File Browser portion of the window, or click Tools -> Install OS.
To reload the device’s OS using another TI-Nspire or TI-Nspire CAS device:
• Connect the two devices using the USB Mini A to Mini B cable. The end marked A should be inserted into the sending unit, while the end marked B should be inserted into the receiving unit.
• On the sending unit, access the document chooser by pressing [Home] [7]. Once in the document chooser, press [Menu] and choose 9:Send OS…
NOTE: Users can only send an OS to a unit of the same model. Users cannot send an OS from a TI-Nspire to a TI-Nspire CAS.
Please see the TI-Nspire guidebooks for additional information.


Hope that helps.

Does not power up after corroded batteries are replaced.


Sometimes these is corrosion on the contacts from the corroded batteries. Try cleaning it off with some sandpaper. Make sure to thoroughly wash your hands after or use gloves!

Good luck.

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.

• 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

If the TI-Nspire/TI-Nspire CAS is a Clickpad, hold down [Home] [Enter] [P], 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 fixed several TI calculators for a school that had loose or corroded battery contacts. Cleaning the contacts and bending them a bit to get a good grip on the batteries got them going. You can try this on yours and see if you have any luck. Also try another set of batteries on the off chance one of the new ones you installed is bad (it does happen, and isn't one of the first things you'd think to check) or use a battery tester. If the batteries are good and the calculator still doesn't work, something inside has failed. Either go for the refurb or (if that specific model isn't required for school) see what similar brands and models are available. There might be something suitable for less than the TI price.
