Hello All - I hope someone can help,
My husband's HP15C seems to be 'stuck' in the User Mode. The manual states that pressing f+USER keys again will deactivate this mode. Nothing happens when the f+USER key is pressed and USER annunciator continues to display. Anyone have any ideas on how to fix this? Any help would be greatly appreciated. Thx.
