From your description it could be the battery compartment it does not conect on the main circuit
if you can open and check the connectors it might be loose
if it will not help and you still want to fix Calculator let me know

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 hold the diamond key. Press and hold the + key for a few seconds and see whether the screen becomes legible.

If this doesn't do it, please reply to this post and we'll go on from there.

Turn the calculator on (or at least press the ON key). Press and hold the diamond key, then press the + key repeatedly to see whether the screen darkens.

If this doesn't do it, please reply to this post and we can try other things, though they may cause the loss of the contents of memory.

If this doesn't do it, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does the calculator turn on now?

When I turn the switch on, ti-89 titanium does not turn on.


If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.

The only option or keys that will work is the ENTER key and the arrow keys. Try to get your arrow key to work by arrowing down and hit enter hopefully change you to something different.
Next, if at all possible can you hit the MODE key or get into the mode. If you get into the MODE select F3 and then arrow down twice or all the way to the bottom and at APPS Desktop select 1:OFF and then hit the ENTER key. Next, What I really think you need to do is reinstall the Ti 89 OS software. To do so you would need to connect to your computer or another Ti 89 Titanium to your Ti 89 Titanium. If you have Ti connect computer software (from the Ti site) connected to your Ti 89 Titanium it might help you more in troubleshooting any further problems too. You might be able to delete corrupt files that would free your calculator up and start running better.
