    I have the same problem. It was working fine. I put it away for summer vacation and in august it was dead. I also changed all the batteries and still nothing. I think it might just be poor TI quality.

    i also put my ti84 plus away in the vacation, it lay next to my books. after the vacation i tried to turn it on, but the batteries were empty. so i put new batteries in it, but the screen only displays the cursor and a white line on the screen for 2 seconds, and then it turns off. It hasn't been in water, heat, sunlight or anything.

Same problem here:
- TI 84 Plus is dead (yesterday alive and kicking),
- (and exam statistics tomorrow).

I removed the 6 torx-screws, and removed the backside (battery-compartment) from the frontside (screen and motherboard). Once the screws are unscrewed, I used my nails to unclip the two parts.

What was wrong:
Immediately visible was a tiny but fatal corrosion on the two little metal-covered spots on the motherboard, where the metal extensions from the battery-compartment (the backside of TI84) touch the motherboard (frontside). So the power was no longer connected to the + and - entry spots of the motherboard.

I tried to clean the corroded parts, but the thin metal was corroded away, so I bent the two flexible extensions from the battery-compartment a little bit sideways, so they could touch a fresh, non-corroded part of the + and - entry spots on the motherboard.

SOLVED!! My Texas Instruments TI84 Plus works again for 100%

IMHO this corrosion (Cr metal extension of the battery-compartment, and Cu on the motherboard) can be avoided by using golden contacts like in the rest of the hardware industry. This corrosion problem is a ticking time-bomb, good for sales but not good for our trust in this product ... According to Murphys Law these problems allways occur when you have an important exam the next day ...

Hope it helps.

There is a chance there is a battery leakage and the contact is spoilt. That's what I'm facing now as well

Is there areset button my keys are frozen

Unfortunately, you can only access RESET from within the menus of the calculator. You will have to remove all of the batteries and let the system naturally reset. The TI-84 Plus uses five batteries: four AAA alkaline batteries and one SR44SW or 303 silver oxide backup battery. The silver oxide battery provides auxiliary power to retain memory while you replace the AAA batteries. Re-install the batteries and reprogram your functions.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...

The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

My calculator periodically will simply die. When

When the calculator is turned ON, power to refresh the RAM is supplied by the main batteries. However, when it is OFF, the RAM relies on the backup battery to keep itself refreshed.
If you get the RAM CLEARED message whenever you turn calculator ON, it most certainly is due to a depleted backup battery. You will have to replace the backup battery.

To avoid losing anything important from RAM (what do I say, you are already losing the contents of the RAM), make sure that main batteries are still good, then replace the backup battery.

You can verify the state of the main batteries in a battery tester or by connecting the calculator to the computer with TI USB Silver cable and TI Connect software. If you run into problem such as calculator not recognized it is most probably due to weak batteries.

When you connect it to computer try updating the OS if OS version is not 1.19.

How can I revive my TI89 after two years of not using it?

It could be that you need to replace the backup battery located behind a little door with a screw in the battery compartment. If this doesn't work, try resetting your calculator by leaving backup and AAA batteries out for about 8 hours and reassembling it. Hopefulyy this will work. Good luck

Need to know how to use the calculator to solve confidence intervals for the mean

I know that you can do 1 and 2 variable statstics, several kinds of regressions analyses, forecasting a value, make statistical graphs. I give you a link to the manual, which you will read to see if the calculator perfoms the calculations you refer to.

Hope it helps.

Texas Instruments TI-30XA Calculator Problem

Either battery is dying, or circuit board has gone, or connector cable loose.

You can replace battery by removing 6 screws at back of calculator, but cost of battery is around 40% of buying new TI-30XA for $10 from Amazon, Staples or elsewhere.

I've used TI-30XA's for years, batteries usually last 2-3 years, then I buy new calculator. The one time I tried to replace battery, fading display still problem, so circuit board had gone bad.

So you could try battery replace and may be OK, but also may be waste of time and $$

Help my calculator!!

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 at all. 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.

My TI-89 Dies out fast

If you download games and some third party software can be running all the time draining your batteries. Some of the APPS with Ti 84 will do the same thing. I'd try and find the problem software and delete it.
