Hi, I don't know why, but the "ON", "0", "2" and "3" buttons of my hp48 gii are loose. It's pretty annoying, and the "0" doesn't even work very well, is there a way to repair it manually? Did this happen to anyone else?
Every time I try to turn it off, the calc locks up because I hit red shift and ON, but the ON button is loose so it locks up...
