Calculator won't turn on...
« on: December 01, 2009, 03:42:42 pm »
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
Quote
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.

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?
