[HP-35s] Are bad keys fixable?

True, it doesn't have trig functions, but it is a smaller and better built pocket calculator than an Hp 35s. And it has a better solver, that really allows you to input all the conversions and other features you do need in long variable descriptive names (admittedly, six characters, but 6>1).

I have a 35s and while I like it, I like it least among my many HPs.

I appreciate the tip very much but I prefer the scientific kind. Will probably pick up a 32s.

I had some success in "fixing" a key on a HP35s bought off eBay. Its "+" key required a stronger press to register. I flushed the keyboard with a larger dose of alcohol (pure isopropanol - beer, wine and whiskey are less suitable). Used a syringe to squeeze the liquid between key cap and front panel a few times, shook droplets off and left to dry.
Also worked for a HP 10B with a non registering key. At least worth a try.

No luck. I gave it to a friend at work who isn't interested in programming. Switched it over to ALG and should serve him for a while.

Thank you for the tips.
