How do I change batteries in Texas Instrument B.35 Calcuator?

it is broken get a new one

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. If this doesn't do it, please reply to this post and we'll go on from there.

Possibility: Some third-Party programs (games essentially) are installed on the calculator. They may be ill-designed and circumvent/turn OFF the Power saving features of the calcuator.Also, Texas Instruments recommends to use alkaline (non-rechargeable) batteries only.

you need to install the Os
you need a cable with adapter to connect to the computer and upload the Os
if you want to fix this let me know
