Would the HP-15C Limited Edition Firmware Age Away?

[TheKaneB]

My 15C (the original model) would randomly crash and lockup while using dead batteries. I'm not sure about the 15C LE though, since it is a very different machine. If the system gives you a Pr Error most definitely the chip is working but something could be off. I wouldn't dismiss a corrupted memory with 100% certainty. I'm not talking about flash cells discharging themselves but electrostatic discharge could in theory fry those chips (I know, they have ESD protection most of the time, but you never know).

Anyway, let us know how it goes.

There must be a lot of those floating around my PC when I'm coding ;-)

You must have a lot of "alpha" software there

(bad pun, I know, shame on me)
