Re: calculator is frozen

Well, not a long time ago I have had a similar trouble regarding to my Texas Instruments Calculator Voyage 200. It was forzen too doing some calculus. Also, one friend had a similar problem regarding to the fozen calculator... I fixed it by reading in the manual that it can be reset!!!...There is a combination of keys that you can press to reset the calculator...this obligates the calculator to load the OS from the EPROM memory where is this basic sofware!!!... If I do not remember wrong the keys are: 2nd + Lock + on/off keys!!! But try to look for the manual and in some part of it is those key combination!!! Good Luck!

Re: calculator is frozen

For a long time, I was resetting my calculator (TI-89 Titanium) upon encountering an assembly-program error, by taking out all the alkaline (AAA) batteries, replacing them with a single, almost dead battery, taking out the backup battery, putting it back in place, and then putting the good alkaline batteries back in. Recently, however, I found out about another method, which is much less involved (for one thing, it doesn't require a screwdriver, unlike my previous method, for which one is required in order to remove the battery cover for the backup battery, as the battery cover is screwed down). After some searching, I found in TI's official guidebook for my calculator (Part 2, the electronic version of the guidebook) where it says exactly what to do if the "TI-89 Titanium appears to be 'locked up' and will not respond to keyboard input. "The following action clears RAM. This erases all [unarchived] data, programs, and user-defined variables, functions, or folders. "Press and hold [left arrow key], [right arrow key], and [Second key]. Then press and release [ON]. "The following action clears RAM _and_ Flash ROM. This erases all data, programs, user-defined variables, functions, folders, Flash applications, and the user data archive. "1. Remove one of the four AAA batteries. "2. Press and hold [(-)] and [)] as you reinstall the battery. "3. Continue holding [(-)] and [)] for five seconds before releasing." (From page 952 in Appendix B: Technical Reference)

When you unarchive a program, you extract it from archive memory and load it into the RAM or working memory. However that is limited. Depending on the other data or junk that clutter the RAM, there may not be enough RAM left to load another archived program.
Clear the RAM , delete what you do not need or transfer it to a computer as backup.

Same as last time

Be reasonable in what you say especially when you seem to infer a blinding truth. If your screen were broken you would not be able to "FIX" it through a connection to another calculator.
I know. Sooner or later you will post another similar question so better learn what the real problem is.
Casino swamps your memory and messes up you calculator. If no more memory is available you cannot get any response from any key.

Play Casino as much as you want. Stop the game before you win that fateful 120000 dollars. Reset the Ram and play again.
Reinstalling the OS by connecting the calculator to another unit effectively reset the RAM and kicks casino out of memory.

To reset the RAM before the calculator is completely frozen, press [2nd][MEM][7:Reset][1:All Ram][2:Reset] [ENTER]

Can not get it to start up after putting in all five new batteries. screen is full of wierdness but will turn on/off.

Where that ''weirdness'' is coming from, I cannot say, but you can press the CLEAR key to clear the screen. Reset the calculator Ram.
Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Press [CLEAR] to erase the "Ram Cleared" message.

Make it a habit to exit thid-party programs/games after each use. They have a tendancy to get stuck in RAM, thus preventing you from using your calculator.

Hope it helps.
Thank you for rating the solution.

RAM Cleared

This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.

Garbage Collecting from hell

Hey soccerman
don't worry man, It's probably just frozen. So try hitting on. This MIGHT break the garage. Do what ever you have to do to try to get it to stop. I can't say how important it is to try to get it to make it stop. If you take out the batteries it will stop but if it's truly frozen it's likely it might come back to the same screen then you will be royally SCREWED. so if you get it back to the normal screen you need to try to get rid of some stuff.
calculators are much like computers they have RAM and a hard drive. However the hard drive is just called ARC space. so your computer is trying to get rid of stuff aka garbage collect so that it can find more space. so you need to hit 2nd then + then go to memory manager and delete some stuff. most archived programs run around 16,000. so like when i fix people calculators i often delete TI sample and TI problem simulator. that should free up enough space for you. then archive your games so that they won't get deleted. (you archive stuff by hitting enter when your in memory manager) it doesn't matter as long as you run them through mirage. that will give you more ARC and RAM space. just to let you know. when you make these changes it will garabe collect again or defragment. don't freak out just let it do it's thing. GOOD luck hope this helps. tell me if it doesn't work i'll try to help again

Garbage Collecting

graphing calulators work much like computers. The have RAM space so they can remember what you have done recently and stuff like that. So when it's garbage collecting it means it's trying to find more space. This generally means that you don't have much much ARC or RAM space left. You can see this under your memerory manager. (2nd + enter) then you can reset your calculaor(2nd plus 7 1 2) or you can go to memory manager and unarchive your programs. Fur an example you have TI 84. Most new TI 84 have sientific tools. so if you don't you it take away the archive (*) by pressing enter and then hit DEL. the more RAM space and ARC space should make it so it doens't garababe collect. Hope this works. i can help you more if this doesn't work. GOOD LUCK
