The calculator uses a battery in addition to the solar cell. If the battery runs down you need to replace it. Turn the calculator over and you'll see the battery compartment in the upper-right corner (with a screw holding it shut). The calculator takes a LR44 battery or equivalent.

Make sure you clear the calculator after replacing the battery: press ON SHIFT 9 3 =

Yeah I had the same problem, you need to open your calculator and check if all the screen cables is alright, i had just put sellotape on the back of the screen from inside so that the screen hold better, and it works for me if for you not maybe something broken in the schema but try it. The thing I know for sure the problem is in the screen or from where it get the data the schema. Tell me if it's working

SOURCE: I haven't used my calculator in some time. Now

If it is solar powered and hasn't been used in some time, the battery may have died, permanently. If there is no battery to replace then it is broken forever. Sorry.When batteries are left without juice for a long period of time they die, and cannot be recharged.

Texas Instruments TI25X SOLAR Calculator didgets not all showing


Even if there is an issue with the calculator it is no longer relevant because it is a discontinued product. It does not have a backup battery and it only uses Solar Power. I suggest to expose the panel to sun light to fully activate the display. And then again it may be just old age, and it is time for you to get a more powerful calculator.

How do you change the battery? The solar cell has stopped working.


It does not have any batteries, it's purely solar-powered. Cost for a repair most probably would exceed the value of the device, sorry,

My HP 10s Scientific calculator does not switch on what could be the problem, is it maby because the calculator was left in a drawer and now the batery ran flat hou can I charge it on the solar power...


You can't charge the calculator off the solar power panel. The solar power panel merely conserves battery power when using the calculator in a bright environment. Try putting in a new battery and see whether the calculator turns on.

Can I do numbers squared on this calculator, and how would I enter this?


The TI-30XA is a scientific calculator with many functions. You can calculate problems with fractions and decimals, as well as solve problems of probability and functions. A scientific calculator computes the number sentence you type in using the order of operations: parentheses first, then roots and exponents, then division and multiplication and, finally, addition and subtraction.
How to Use a TI-30XA
  • Step 1Press the [ON/C] key to turn on the calculator. Press the [OFF] key to turn it off. To use the calculator in solar mode, put the solar panel in the light and then press the [ON/C] key. To turn it off when in solar mode, slide the calculator cover back on and it will automatically shut off.
  • Step 2Replace the batteries by first removing the cover and placing it face down. Use a Phillips-head screwdriver to unscrew the back panel. Remove the back panel and change the batteries. Screw the back panel back on. Press [OFF] [ON/C] and [ON/C].

    New Battery???


    Hello,
    Try to expose their solar panels to direct sunlight (10 or 15 minutes), just to see if they come back to life.

    Hope it helps.
