    Please read the description carefully. To ask it another way: the automatic power down (APD) feature automatically powers down the ti 84 plus, causing the signal to ti connect to be lost. How do I disable the APD feature to prevent the signal from being lost?

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

SOURCE: How do I turn off the vertical asymptote feature?

Hello,
There is no vertical (or otherwise) asymptote feature on a TI84PLUS. It seems to you that the calculator is drawing the asymptote. However when you plot a CONNECTED Graph a line is drawn from one point to the next: The last point on one side of the asymptopte is thus connected to the fisrt point on the other side, effectively mimicking the drawing of the asymptote.
To get rid of this spurious effect, draw dotted graphs, but you will see fewer points, because the points are drawn at constant intervals in X. This is set by the Xres variable, in the Window configuration screen.

Hope it helps.

SOURCE: how do you put degrees mins & secs in a ti 84

The DMS symbols are available under the ANGLE menu
Press [2nd][APPS] (ANGLE)
Under that menu you find the degree and minute symbol. To enter the seconds unit you use the key sequence [ALPHA][+] (")
To enter 1deg 15 minutes and 37 seconds
1 [2nd][APPS] [1:deg] 15[2nd][Apps][2:'] 37 [ALPHA] [+]

To enter a number in decimal degrees (eg 15.37)

  1. If angle unit is the degree just enter 15.37
  2. If angle unit is the radian , you must specify the angle unit as degrees: To enter 15.37 degrees you type 15.37 [2nd][Apps][1: degree] [ENTER].
To convert from DMS to DD and from DD to DMS, you use the sequence [2nd][Apps][4:|=>DMS].

When i turn my calculator on it says "RAM cleared". It is then very slow . . . what is wrong and how can I fix it?


Hi yeager anna,

Since the calculator operates slowly even after the RAM has been cleared, I'd say, "Your OS must be corrupt." You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix this problem by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries when installing the new OS. If you need additional instructions your welcome to read my Ti 84 Plus solutions. I pretty much tell how you can install the new OS with another Ti 84 Plus calculator or, connecting the computer to the calculator to install the new OS. You can view my solution to install OS by clicking, "Ti 84 Plus OS installation." Just stroll down to oneplusgh's solution at that posting and, I cover a lot of topics you may need advice on to install the new OS.

If you need instructions to downloading and installing TI Connect on a XP or, Mac computer click, "TI Connect on a XP or Mac computer." I realize this posting was for a later OS but, this link will take you to the latest TI Connect software and, newest OS too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

If you need instructions to downloading and installing TI Connect on a Windows 7 computer click, "TI Connect on a Windows 7 computer." Just follow Procedure 3. You can also get instructions at this link on how to install the Ti driver to link computer and calculator. I realize this link instructions were for a Ti 89 calculator but, they will work for a Ti 84 Plus too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

My instructions is geared to save you a lot of hardship. No matter if your having to install Ti Connect or, the newest OS for your calculator. I do not use TI OSDownloader because, TI OSDownloader might not give you the newest OS for your calculator. My instructions will. If you have any questions just post a comment and, I'll respond quickly.

Hi purzabumafu8,

You need to re-install the Ti 84 Plus OS on both calculators, ASAP!!! You can fix these problems by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the USB or, IO link ports. Then they can send you a copy of their OS, while you receive it on your Ti 84 Plus. Hopefully, your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work. Link the two calculator together through the USB or, IO link ports with the proper cable. If don't have another reliable calculator to connect too, you'll have to connect the calculator to a computer to download the OS, goto Procedure 5. If your downloading off another calculator goto Procedure 1.

Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.

Procedure1. Procedure to linking to another calculator.
On their calculator press, [2nd][Link][G] [Right-Arrow]. On your calculator press, [2nd] [Link] [Right-Arrow] [Enter] and, then press [ENTER] on their calculator too. Their calculator should say, "TRANSMIT" and, your's will say "Receiving." Then on both calculators once transfer is complete press, [2nd][MODE] to quit and, return to the Home screen. If the OS was transferred then your finished with these procedures. If your calculator won't turn on or, is locked up try the Procedure 2, below.

Procedure 2.

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
"Waiting...Please install calculator software now". If calculator did not turn on or, is still locked up goto Procedure 3, unless already did Procedure 3, then goto Procedure 4. If you calculator does come on and is responding and, your connect to another calculator goto Procedure 1. If you calculator does come on and is responding and, your connect to a computer goto Procedure 7.


Procedure 3.

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. Goto Procedure 2.


Procedure 4.

If the above process did not work. Try re-doing the Procedure 2, and, this time extend the time in Procedure 3, by 5 minutes to 10 minutes before you put all the batteries back in the calculator. These calculators can be a little stubborn at times so, keep trying Procedure 2.



Procedure 5.

If you can't find a calculator to connect too, you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS.
Procedure 6. Procedure to installing the latest Ti84 Plus 2.55v. MP OS. TI OSDownloader does not always install the latest OS.
You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". 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 Ti84 Plus family operating system will download to you.
Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed. If your calculator will not turn on or, is locked up goto Procedure 2. Or else goto Procedure 7.

Procedure 7.
Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.
Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install. Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.

I jus bought a TI-84. when i turned it on it said RAM cleared. now there's a blinker on the screen. every time i press a button, nothing happens. whats wrong with this brad new calculator


You need to re-install or, update the Ti 84 Plus OS. Since you just bought the calculator it is unusual that it is already to that point of clearing the RAM. You can connect a computer and your Ti 84 calculator together once you downloaded and, installed Ti Connect software on the computer. That way you can use the Ti OS Downloader that comes with Ti Connect software to install the newest Ti 84 Plus OS. Or, if you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84.

Get this problem fixed as quick as you can. You do not want your OS to fail any more than what it already has. If you can not find another calculator to connect too, then you can connect through your computer. You may have a long road ahead of you getting the Ti Connect software and, drivers working right. Just remember to come back to your posting here and, post a comment of what ever is failing. This will notify me right away and, I'll walk you though it if necessary.

My TI-84 calculator says "Garbage Collecting" and won't work, how should I reset it?


Found at www.epsstore.ti.com

What can be done if a TI-83 Plus family or TI-84 Plus family calculator displays Garbage Collecting... for more than 20 minutes?

The garbage collection allows the cleanup of unused archive memory. It deletes unarchived variables from the user data archive and it rearranges the remaining variables into consecutive blocks. When a variable is unarchived, the Archive free memory amount increases immediately, but the space is not actually available until after the next garbage collection.

If garbage collecting is more than 20 minutes, the calculator has possibly locked up and will need to be reset.

The reset procedure will delete all the items that are in the memory of the graphing calculator. Use the reset procedure below:
• Remove 1 AAA battery.
• Press and hold down the [DEL] key.
• While holding down the [DEL] key, replace the AAA battery, and press the [ON] Key.

The message Waiting... Please install calculator software should appear. At this point, it will be necessary to reinstall the calculator's operating system.
• Connect the calculator to the computer using the TI Connectivity Cable or DirectUSB Cable.

Please post if this was helpful...
• In Windows®, click on Start >> Programs >> TI Tools >> TI Connect >> TI OS Downloader.
• In MacOS® X, open Hard Drive >> Applications >> TI Connect >> TI OS Restore.
• Follow the directions on screen to reinstall the calculator's operating system.

My calculator drains a set of four batteries with every use. Why?


I am not sure what every use means: duration, programs running etc. But that drainage is properly excessive. TI estimates that with 2 hours a day of usage, the batteries should last a school semester.

Possible causes of rapid drainage.
The most common causes of rapid battery drain are mismatched batteries
  1. Batteries of different brands
  2. Batteries of different types (alkaline (1.5V + rechargeable NiMH 1.2V)
  3. Batteries of different charge levels (new batteries with old ones)
  4. Negative charge build up
Another cause of rapid battery drain is the use of third-party programs: Certain of them keep large amounts of data in memory. Some of them are tweaked to bypass the TI power management scheme and disable the TI APD (automatic Power Down ) after 5 minutes of inactivity.

Possible remedies
  1. Remove all batteries (main batteries and backup battery)
  2. Leave them out of calculator for about 15 minutes. (Beware that this will clear the contents of the memory and that data will be lost along with all applications installed). However Applications cam always be reinstalled once calculator returns to its normal state.
  3. The possible benefit of the removal of all batteries is to make the negative charge build up disappear.
If that fails
If the foregoing steps fail to restore the calculator to its normal behavior, you may have to contact TI Customer Assistance by filling out and submitting a customer assistance form.
