Broken Calculator

[Globex]

My TI-84 Plus graphing calculator has stopped functioning. I can turn it on but it automatically shuts off after a few seconds. Does anyone know what I can do to fix it? Where should I go to get my calculator repaired?

Change the batteries? Did it get wet?

I've tried to change the batteries but it didn't fix the problems.

Did it get wet?

No

Pencil and paper.

Throw it away and get another one. Electronics can almost never be fixed for less than the cost of replacement unless they are major big ticket items that are fairly new.

Use an '89. '84s are for people who don't do calculus on a regular basis.

How do I get support for my TI84 if I live in Iceland?

Bah, use an HP50. TIs are for those who don't constantly use their calculators to do coordinate geometry

I read through the technical support information and it suggested that I reset my calculator. After I did that, my calculator stopped shutting off automatically but it takes about 3 seconds for it to respond when I try to punch in numbers and commands. I can't seem to get it to turn off without removing the batteries.

Do you think that replacing the lithium button battery will help? I've replaced the triple A batteries but I haven't replaced the small button battery yet. Is the problem with the batteries or is the calculator itself broken?

My TI83 (this was before the 84s were released in 2004) was rarely used for math. It did let me play mazes and other simple games in Trig though.

I hate the entire series of calculators though. I highly resent my math teacher (and by association, Texas Instruments) for trying to fail me when my mom was too broke to buy me a hundred-dollar calculator for an Algebra I class.

Well, the 83s ok, it's just a complete hassle to program it for anything more complicated than little games. The 89s do better, because you can get a USB cable and emulator for PC based application development. The HPs all do RPN though, which is extremely nice, they're much easier to program, and are generally more powerful. Surveyors use them the world over to do their Coordinate Geometry work, and they can even be taught to interface with a $10,000 Total Station.

horsehockey deal about the schooling though, even though TI has effectively nothing to do with it.

The 89's CAS and pretty print makes it far superior to the 84.

I haven't extensively used an HP calculator, but the RPN does seem like a decent feature.

Pretty print helps work around some of the difficulties, but doing complex equations can still be annoying.

Problem solved. I replaced the button battery and it started working again.
