Ok, after going through 2 years being used 10 hours per day every day of the week, being dropped a few times in my day of hi school (2002-2003), going through torture such as letting BSODs run for 10 minutes by running prgmA without installing Ion first, the making of more than a dozen of my RPGs, as well as a lot of other programs, it seems my 6 years old TI-83+SE is heading toward the end of its life.
Two days ago I put in fresh new Duracells in my TI-83+SE, and used my calc for about 15 minutes, then turned it OFF. No program has crashed.
Today the batteries were dead. And the same thing happened with the previous set of batteries, altough it took one week before I notice.
I don't know if it,s the batteries that had problems, because I tested every batteries and they were all dead, then I changed the entire set. I am curious if it could be the lithium battery that is dead, because when trying each batteries before changing the set I got two RAM clears when turning the calc back ON. However, I don't recall reading anywhere that a dead lithium battery can drain AAA's power like this. All I remember reading is that a RAM clear would occurs if I changed the AAA's when the lithium one is either dead or removed. This leaves me skeptical.
I am wondering if anyone else had any idea if this could be the lithium battery that cause that massive power drain? Maybe I missed something while reading?

| I don't think a dead lithium battery could drain other batteries, especially if they're not directly connected. However, I would try changing the lithium battery first, and then going back and replacing the main AAA batteries. If that doesn't work, something may be wrong with the circuitry, reversing the battery contacts and somehow draining the batteries. I dunno, but I'd try changing the lithium battery. |

Well, one thing that could happen if the lithium battery is dead, is that the calculator relies on the AAA batteries for power that the backup battery would normally provide (when the calculator is turned off). This could be responsible for the battery drain, although I'm just guessing.
I would try replacing the lithium battery, and see what happens. |

| Yeah I made the same suggestion on omnimaga before it shut down but I doubt he will ever see this thread anyway. |

I don't think that is responsible, if the lithium could last longer than the AAAs at it, then everything would be small batteries. |

A battery could provide a small voltage and still last longer than a larger voltage battery. So, the backup battery doesn't provide enough voltage to run the calculator, but it's possible it can outlast the AAA batteries.
However, I don't think the calculator ever relies on the backup battery for ordinary power. It just uses it to refresh ram while the AAAs are removed. So I don't think that a dead backup battery could cause any problems other than a ram clear when you swap AAAs. I'd say your calculator is probably damaged some other way. Sorry

Were they completely new batteries? Also, were they from the same package/brand or not? What brand(s) were they? Were they rechargeable? Have you tried replacing the lithium battery?
We might be able to help you a bit more if these questions are answered... |

| Ok as said in the Omnimaga topic a few days ago I tried with new lithium batteries and new AAAs (good ones), and at first things seemed fine, but now the calc is doing the same thing again. So it's definitively the calc that has a problem. Oh well, I guess I will just try getting a 84+ when I get more money. My priority is a new computer right now (around October) to run Starcraft II at decent speed. But I still have anoher TI-83+ that works perfectly anyway |

Man, both Omnimaga AND your calculator died around the same time... you have some kind of bad omen following you.  |

That should be everyone's first priority.  Try buying the parts to put together a desktop instead of buying one from a company, as you can shave off $200-$2000 by doing that. I suggest you start at Newegg.com.
Once that is taken care of, I think you should go for the 84+SE instead of the 84+ if you have the cash, as it does pack in as much and processor speed as the 83+SE.
@JoostinOnline: You are not the first person to comment on my method of asking questions... 
(PS. I know this is off topic, but why don't graphing calculators have a graphics card?)

well computers parts here costs more, due to the taxes and import costs. I guess i could always check Newegg tho, but their shipping costs must be very high for me since I live outside USA. As for the calc I will go either for 84+ or Nspire. I will only choose Nspire if the 84+ is 100% supported in it though. If I get more money maybe I will choose the 84+SE, but it's like $177 where I live, while the Nspire is $160. Plus I dont really need 1.5 MB of memory really. IIRC Pokémon Purple is meant to fit on the regular 84+ too

I'd say that an 84+ on eBay would be more worth it. Just watch out, I ordered an 84+SE off of eBay and some a sent me an 84+, but I got him to give me a nice $30 refund for not reporting him, which got my an 84+ for $30.

I got my 84+SE off of ebay, I looked around and you can get some pretty good prices if you are patient enough. (don't be too patient like my mom and look around for 1+ months before even considering a purchase ) |

| I got a brand-new, never-been-opened Nspire for $100 off ebay, almost half the store price ($180) |
