1. A base comprising:
- a frame;
a keyboard partially enclosed by the frame, the keyboard being configured to wirelessly communicate with a computing device, the keyboard including a first side, a second side adjacent to the first side, a third side adjacent to the second side and opposite from the first side, and a fourth side adjacent to the first side and to the third side and opposite from the second side, wherein;
the first side of the keyboard contacts a perimeter of the frame;
the second side of the keyboard contacts the perimeter of the frame;
the third side of the keyboard does not contact the perimeter of the frame; and
the fourth side of the keyboard contacts the perimeter of the frame;
a battery configured to provide power to the keyboard;
a mount hingedly attached to the frame, the mount being adjacent to the third side of the keyboard;
a single coil coupled to the battery, the single coil being closer to the second side of the keyboard than to the fourth side of the keyboard and closer to the first side of the keyboard than to the third side of the keyboard, the single coil being configured to induce a current from a magnetic field generated by a charging coil of the computing device to charge the battery, the base not including any charging coils other than the single coil; and
a sensor configured to;
detect a proximity of a magnet in the computing device;
prompt the keyboard to power on based on detecting that the magnet is proximal to the sensor; and
prompt the keyboard to enter a low-power mode based on determining a lack of proximity of the magnet to the sensor.
