hp50g left arrow key

[Randy]

The up, down, and right arrow keys on my 50g work well. In edit mode,
an arrow key closure moves the cursor 1 position first time every
time.

The left arrow key did not feel different but the operation was
erratic. A key closure might or might not move the cursor.

Opening the case was beyond my ability.

I put a small amount of isopropyl alcohol in and around the left arrow
key. After several key closures the key began working consistently.
And has remained working for several weeks.

The isoproply product I used is a general purpose cleaner. It claims
to be: rapidly evaporating, zero residue, non-corrosive, and safe on
plastics. Interestingly, the fine print says low grade plastics might
be affected. I didn't see the disclaimer until I had already used it
but see no ill effects.

Perhaps this will be helpful.

This can be used as a "Turing test" to distinguish a real person
from a calculator -- isopropyl alcohol will make a real person
more erratic (and sick) than even ethyl alcohol,
whereas a mere soul-less calculator will be improved :)

Try pouring some isopropyl alcohol into Newt Gingrich;
if he becomes more professorial (and even consistent)
then he would probably make a fine robot,
although not necessarily a fine leader :)

But it will improve him in any case.

Alcohols is okay for most plastics except Plexiglas. See

If you DO need to do some calculations, buy Casio, TI or Sharp

Several creative responses. Don't have a good or even a bad test to
determine if soul and politicians are mutually exclusive.

If you need a calculator, use an RPN HP machine. Casio, TI or Sharp are
simply second choice tools... ;-P
