RE: Restore a Pioneer keyboard (27s)
Hi! after fixing this HP27S everything seems to have gone well.
But there is a strange problem: if I leave the calculator unused for a long time (a month? Two months?) It will no longer turn on unless a reset (ON-C) and when I turn it back on all the memories, date, time and settings are lost... How come? it's normal? the batteries are in excellent condition.

Thaks in advance
Hardware: Hp48S - Hp50g (5x black + 1 blue) - HP39gII - Hp27s - Casio fx-CG50
