Question about Texas Instruments TI-89 Calculator
As far as the powering down goes, many calculators do that automatically, including the ti-89 series (at least mine does). In regard to the non-functioning keys, I would have to say that the circuit running that particular row of keys was fried in the accident, because the whole block has lost functionality, as opposed to a single key. It may be a prime opportunity to upgrade to a Ti-89 titanium.
hope that helps :)
