When installing a keyboard, to make sure the keyboard lays flat, the keyboard ribbon cable must be bent at
the appropriate point before installation. There are markings, typically a thin white line across the breadth of
the cable, that indicate where to bend the cable. On HP ProBook 440 G3 models, bend at the marking labeled
S1 (1), and then fold the cable over (2). If installing a backlit keyboard, follow the same procedures for the
backlight cable.
