HP-48SX battery leakage and hourglass always on

[paolgab]

Hi
this is mi first post here, so thank you to everybody that will take the time to read my post and may be answer.

My old HP-48SX had a battery leakage that I have discovered right this morning.

I've cleaned at my best the battery compartment form the salt and replaced the battery with three new and it works well as usual.

The only nuisance is that the hourglass is still on.
I mean the icon on the almost right top of the display that says that the calculator is busy.
It is always on when the calculator is on. If I switch it off the whole display goes off. It has the same behaviour with the deep sleep keys.

I think that the battery leakage damaged something, but before open the HP and put it at risk, I'd like some clou.

The HP was stocked in my studio in vertical, along the long side:

Code:

thank you very much again
