1. A keyboard, comprising:
a force-sensing trackpad comprising:
a touch receiving surface; and
a printed circuit board (PCB) coupled to the touch receiving surface;
a base plate spaced from the PCB;
a plurality of resilient members coupling the base plate to the PCB;
a bending sensor configured to detect bending of the keyboard;
a processor; and
a memory storing instructions executable by the processor to:
use at least data from the bending sensor to determine that the keyboard is bending;
at least on condition of determining that the keyboard is bending, adjust a spring constant value to an adjusted spring constant value; and
use the adjusted spring constant value to determine a force applied to the touch receiving surface.
