I have a TI-84+ SE.
For some reason, the calculator gave me an option to group archived programs. Curious idiot that I am, of course, I immediately try it out. The screen flashes random displays for about a second, then fades to white. On button unresponsive. Batteries pulled, re-inserted, tried again: nonresponsive. Swapped with another calculator's. The other calculator didn't respond when it was turned on. (Batteries probably drained...!) My calculator didn't do anything either.
So now I'm in a bit of a hard place. I have a VERY important math exam on Saturday (today's Tuesday). Any ideas? There's also quite a bit of stuff on my calculator that I would like to recover, if possible.

Good luck.
I don't know what happened, but it sounds like this:
from: http://ourl.ca/3687
TI-83+SE OS 1.13 and 1.14 (no clue about OS 1.15 through 1.17)
Grouping archived files
Trigger: Have the archive memory be saturated, which means close to GarbageCollection time (when archiving starts taking a long while)
Effect: The closer to a garbage collection you are, the more archived files will show up in the GROUP menu when selecting files to group. At first, very few files will show up, but eventually, every archived program shows up. DO NOT TRY THE FOLLOWING IF YOUR WARRANTY IS VOID. I WON'T HOLD RESPONSIBLE FOR DAMAGES CAUSED TO YOUR CALC! THIS IS EXTREMLY DANGEROUS!!!!!!!Grouping such file causes bad effects ranging from RAM Clears to bricked calc (the first time I intentionally did this, I had to return my calc to Staples with the receipt to get a new one in exchange. The second time I accidentally selected one of these files when doing a backup of one of my game I was working on and the calc simply locked up, but it could have been worse, altough I think the calc was still under warranty at this time)
Fix: Garbage Collect. If you grouped such bad files, do the battery pull trick then press ON, else, do it again while holding DEL then follow instructions on screen. Else, try reinstalling the OS. If that fails too, take your calc back to the store with your receipt.
Workaround: Update to another OS.
Mabey try an OS resend.
Did you take out all 5 batteries (including the backup) and try leaving it face down for a while?
-
How do you reinstall the OS if the calc doesn't turn on? I'm confused.
-
Good point. I'd try taking all the batteries out a hoping it will work.
-
I've taken out the four AAA batteries, but don't have (easy) access to a screwdriver at school, so I couldn't try the silver one.
Won't pulling that clear all memory?
-
Mabey. I don't remember. I did it once, but I forget what happens.
Did you try taking one battery out and holding [del] and [On] as you put it back in?
-
Crashes
Not fun. An unavoidable part of assembly is the crashing. Some minor glitch in the program, a logic error, whatever...the end result is the same: ka-boom!
Panic Level
1 Press [ON].
2 Open the battery case, take a battery, and swivel it on the springy terminal.
3 Take out all four batteries and re-insert them.
4 Take out all four batteries and the lithium backup—you'll need a small phillips-head screwdriver (the screw is pretty dang long).
5 Take out everything and let the calculator sit on its face for a couple hours to let the power drain out.
6 Get the reciept and take the calculator back to the store. If they refuse to exchange, make the best of a bad situation and get a TI-86 or 89 this time. Oh, and instead of just throwing the thing away, position it on the sidewalk, and have it and a baseball bat repeatedly attempt to occupy the same co-ordinates in space-time. The spritzing LCD oil does wonders for that ancient bloodlust.

Mabey one of these works. For the record, I don't agree with #6.

It will clear all RAM, but not archive (or OS).
-
No. 6 sounds satisfying...
Anyways, I managed to get the battery pull + DEL trick to work. I'm still not sure if I'll keep my archive/group, but that's all that matters right now.
Thanks so much - will let you know how it goes! (My parents were no help at all - they thought I dropped it. -_-)

Yay! It works! Hopefully there woln't be any long term damage. (Altough I doubt if there will be any.) :)
-
Cheers! OS reinstall worked... so somehow battery trick + DEL works even when your calculator doesn't turn on. And I got all my programs (well, archive) back! (Including my radical simplifying program, which is incredibly handy. :P)
Now, to fix this damn mouse on my computer that stopped working...
-
:)
On to the next problem...
Edit: Did you try turning the power on to your computer while holding down delete? (jk :P)
-
Graaagh. It doesn't work even after a reboot. (And holding down the Del key. :P)
I'll get along well enough with the accessibility feature that lets you control cursor with number pad. Unfortunately, it doesn't adequately control my cursing... at the failure of my mouse to work. ;)
-
Okay, it turns out that it was out of battery. Bad timing. *headdesk*
Last question - What is respect, and how did I get +2?
-
Respect is how much people respect you. I think yours can from one of your posts about Illusiat 13. To give people respect, click the thumbs up in the upper right of a post.
What os number is your 84+se?
-
I am glad you got your calc to work again. This is probably the most dangerous TI-OS glitch ever. I didn't even knew the TI-84+ also had it. In my case, even resending the OS still failed, so I had to take the receipt and take my 83+SE back to the store.
Curious idiot that I am, of course, I immediately try it out.
Don't worry, this is the first thing I tried immediately when archived stuff showed up in my group menu on my SE. I was curious how funky the calc would act before RAM clearing. :P
I am the kind of person that have left my calc run on a Blue Screen/Lines Of Death (caused by bad ASM program) for over 3 minutes a few times x.x
As for respect, Omnimaga has a system like Youtube comments rating. People can gives thumbs up or thumbs down to comments, but unlike Youtube, all these positive and negative votes are kept track of and added together, so you can see the total for everyone below their profile. Some french PHPBB forums like TI-BANK got this too, altough you can also know how much negative and positive votes someone received and given
-
What's the Blue Screen of Death?
-
Sometimes, when an ASM program crashes, the calculator will enter into something called test mode. Basically, the entire screen will turn blue (yes, colors) and the LCD will start leaking on each sides of the screen until you remove a battery for two seconds to trigger a reset. It is not recommended to leave the calc in a BSOD state for an extended period of time as it can damage the LCD.
On the regular 83+ calculator, instead of the entire screen turning blue, only a few horizontal blue lines, which can also eventually damage the LCD, will appear.
-
2.43 now. I think it's the most recent version.
Thanks again! :)
-
Calculator BSODs sound... interesting.... I've never messed around with ASM much (mostly Codex and some xlib) and you've convinced me to keep not messing around with ASM (and messing up my calculator). :P
-
So in other words, either TI did not fixed the group glitch on later 83+SE OSes after all, or the glitch returned on the 84+ only. I just don't recall seeing it happen on my 83+SE OS 1.18. I only ever saw it on 1.13 (probably the most buggy TI-83+ OS ever) and 1.14
-
Hmm, I don't want a bsod... Is that the same mode as [mode] [alpha] [S ] ? Or is it a compleatly different mode?
Insorak, I'm happy your calc works. :)
Edit: Silly strikethrough! I had to change it to [S ]. :D
-
Totally different mode.
-
LCD test mode is obtained by sending the byte $1F (there are a few other valid ones, though) to the screen command port (10h). It causes an excessive amount of energy to be sent to the LCD, which makes the crystals turn blue. Not healthy...
Mode+Alpha+S is merely a self-test to check if everything works properly.
-
In other words, the LCD power level is OVER 9000!!!
-
So now why in the world would that feature be included if it hurts the calculator ??? Another one of TI's blunders? Actualy has a good reason? Or actually unintentional? I never actually got to find out :)
-
It's part of the LCD chipset. It'd cost more to remove it.
-
That said, I think in generaly, if you don't let test mode running for too long, it shouldn't cause too much harm.
There's also something you can do with test mode that is triggered by changing the contrast from a high to very low value in an instant. It only works on the 83+SE, 84+ and 84+SE, though. When doing so, the calc seems to quickly flash to black (like, during 0.01 second or something) then display dissapears. To me, it seems like test mode is being triggered during a centisecond approximately, when this happens (kinda similar to when you turn off a TI-89, where blue lines shows up for 0.1 second before display dissapears). If you use xLIB to quickly change the contrast back and forth from low to high value through a loop, the entire screen will turn blue instead of a wave effect like on the 83+. However, it will not be as blue as in test mode, and liquid crystal will not leak outside the screen display limitations. Plus, it can be stopped by simply ending the loop or pressing ON. This can be sort of useful for special magic animations in certain games.

ah i see. That raises my opinion of Ti from -23 back up to -22 :)

lol! Why so bad?
-
With what Texas Instrument did this summer about the key factoring and what they did to the TI-84+ hardware in April 2007, it's very easy to have such low opinion about them now.
-
That and their low customer service :P
(a lot of it was just humor anyway though (^^,)
