Cleaning inside a HP 11C

[Csaba Tizedes]

Thanks for the tips, I have used very similar method, unfortunately I get some vapor behind the LCD and some water remains inside, because I got low battery flashing sign after 10-15 mins.

So I must to use hot air to dry the unit perfectly. I guess nothing inside went wrong, this is similar, when water condensed inside the cold calculator and it can be dry.
