Unfortunately you have to reinstall them. They are lost forever. Once your ram clears everything that is unarchived is deleted there is nothing you can do to recover them. Just re-download them

Error memory when loading calculus made easy on ti-89 titanium


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

My daughter dropped her TI-84 plus. Two batteries came out. When powered on it said "ram cleared" and all her programs and manually entered formulas are gone. Apps are still there, but not...


I'm sorry to tell you that your daughter is out of luck :(
In the ti calculators, most data is stored in ram. this includes programs, variables, etc. the RAM is kept in its current state by battery power. But, when that battery power is lost the ram reverts to its normal state, erasing all data stored in it.
you best bet is going to be to re enter all data possible as fast as possible in time for testing
hope that helps :)

I'm using the t and z test on my TI-84 Plus graphing calculator. When I go to enter data it will only let me enter in the standard deviation and mean but then it gives me an error message that states ERR:...


You do not have enough memory free. You will need to clear RAM and possibly delete programs to free up space.

Pressing [2nd][+] will take you to the memory management functions. From this menus you can delete from Programs, Applications and can also reset your RAM. Doing any of these should help free up enough memory.

When I press any key on the calculator it takes about 2 seconds before anything comes up on the screen. The batteries are new. Any idea what the problem is?


Hello,
The RAM may be quite full. Reset it: Press [2nd][MEM][7:Reset][1:All Ram][2:Reset] [ENTER][ENTER]. Clear the message RAM Cleared by pressing [CLEAR]

If you do not want to reset the RAM you can try to clean it. Press [2nd][MEM][2:All]. A list of all memory comtents appears. The applications, programs or data that are archived have an asterisk to their left.

In the list, select an item you want to delete and press [DEL].
If item is archived, you select it, and press [ENTER]. The asterisk should disappear, The item can now be deleted.

I suggest you select a few items to delete and press [2nd][QUIT] to allow garbage collecting to peoceed.
Delete some other data (apps, programs, ) and press [2nd][QUIT].

Hope it helps.

I need to reset my TI-89 Titanium


There is several ways to reset the Ti-89 Titanium calculator. Other than the one shown to you by K24674, just hit [2nd] [MEM] [F1] instead of [diamond] [MEM] [F1], then:
Press [1:RAM] then select [1: All RAM] or [2: Defaults] and [ENTER] to reset the RAM.
Since you didn't give him four thumbs up because, he did what you stated. I'll tell you other ways to do a reset. The reason is because, you may have a locked up calculator that seems impossible to reset.

Push [2nd] [MEM] then [F1] [3] [ENTER] for yes to reset everything.

If your have downloaded 3rd party shells, games and programs and your calculator is locked up, you may need to take out all the batteries including the small circular one for about 4 hours or more.

If this doesn't work you will have to deal with it, possibly by deleting out what you can to free the calculator up to start operating properly, and re-installing the OS software.

Actually most people don't even need to reset their calculator memory. It is usually just a single variable that their using that is what hanging them up. Just execute the NewProb command to delete all single variables in the folder that your working in by pushing [2nd] [F1] [2] [ENTER]. This only deletes single variables a to z. This method is unlikely to miss you up with other programs, functions that are not archived or can be mistakenly deleted on your calculator. Works real good while working out of the main folder. Hope this helps you!

When i press most buttons it gives me the message ERR:MEMORY i cant access memory so i cant reset ram or delete . also i can not connect to my cpu it says TI-84 plus Silver Edition detected, but couldn't...


From the TI knowledge base and FAQ

How do I correct ERR: MEMORY on a TI-83 family or TI-84 Plus family graphing calculator?

An ERR: MEMORY is given when there is not enough memory to perform the instruction or function. To increase available memory by deleting the contents of any variable (real or complex number, list, matrix, Y= variable, program, Apps, AppVars, picture, graph database, or string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu.
• Press 2: Mem Mgmt/Del.
• Select a variable or data that needs to be deleted and press [ENTER].
• Use the arrow keys to move the cursor next to the item, and then press [DEL]. The variable or data should now be deleted from the memory.
When deleting programs or Apps, a message asking for confirmation will appear. Select 2:Yes to continue. To leave any variable screen without deleting anything, press [2nd] [MODE].
Notes:
With the exemption of programs and Apps, no warning will be given to verify the deletion.Some system variables, such as the last-answer variable Ans and the statistical variable RegEQ, cannot be deleted.

Hope it helps.

TI-84 Calc is FROZEN


I'd try hooking it to the computer using ti connect explorer and see if deleting the programs there would help. I had a calculator that did the same thing and never did fix it. But if your memory can be delete and reinstalled it might work.

Garbage collect error on a ti 89 Titanium calculator. The problem is, is that I cant archive what needs to be archived so that it wont be deleted when I garbage collect to free up space


Hello,
You can interrupt the program by removing one of the main batteries. Put battery back in calculator and turn it on. You may have to adjust contast with [2nd] and [UpArrow] keys or [2nd] and [DownArrow] keys, pressed in sequence and repeatedly until contrast is adjusted.

Reset all Ram.
If you remove apps one at time, and let garbage collector work after each deletion of apps, it may run faster and will not hang.

Hope it helps
