    I have a cheap calculator and it stopped working. So I assumed it was the battery. I opened it up and found a coin cell battery inside and went to Radio Shack and replaced it. I even cleaned the contact on the circuit board and it still won't fire up. I am wondering if there isn't some kind of gimmick to prevent people from replacing the battery. Anyone know anything about this? I am no new comer to working on electronics.

Batteries won't work


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Won;t power up at all. New batteries but I did not replace back up battery. should I? Tried the contrast fix. Son said he dropped it and it got kicked down hall at school. One year old. Any hope?


Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

It's "frozen". won't change from the screen its


Try to reset it by taking out the batteries and leaving to sit for a minute or so, if that doesn't work take out the small battery as well and leave it sit, if you're still stuck you can call ti-cares (800-842-2737) they're generally very helpful.

My 2001 Dodge Durango won't start at times. I replaced battery and had alternator checked. Both checked out fine?? Help! ??


When it won't start, will the engine turn over and try to start, or does it act like a dead battery?

"ON" button doesn't work; calculator won't


Hi,

In most cases this cannot be economically repaired... the cost to repair would be more then the calculator is worth...

My HP35s keeps flashing MEMORY CLEAR. I removed the batteries and reset it with a paper clip. Nothing works.


I'm not sure if it is the only solution, but I had the same problem and I replaced the batteries. My HP35S works fine now.

Previously, however, there was no "battery" annuciator on the screen. This calculator went four years without a bettery change. My HP48GII, on the other hand won't go two months without a change. Go figure.
