Question about Texas Instruments TI-89 Calculator
I've had my TI-89 Titanium for a few months now and have been using it fairly frequently for Calculus and Physics. However, I've noticed in the past few days that whenever I try turning it off (using 2nd + On), it doesn't turn off. Instead, it turns off for a second and turns right back on. I tried RAM resets and took out regular and backup batteries, all to no avail. Anyone, pleaseee?
1) Update the OS from the TI site.
2) check if button is sticking(not necessarily just the plastic button, but what it hits on the inside... you can clean the contacts on the inside of the calc with a Q-tip and rubbing alcohol.)
I don't have much experience with this specific calculator but those are my best bets.

You may get
Memory Error when you try to access an archived variables. From the other hand
Memory Error message is displayed if there is not enough free RAM to access the
archived variables. For correcting Memory Error message use the 2ND then MEM to check RAM free size and 2ND then
VAR-LINK to determine the size of the archived variables that you want to
access. As the third step for correcting this problem deleting unnecessary variable
from RAM and archiving large variables or programs. By the definition, the RAM
free size must be larger than the archived variables

Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.
You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.
Procedure to installing the newest Ti 89 Titanium OS 3.10v.
You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. 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 Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.
Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.
Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the  key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.
Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.
