Abstract: A method for adjusting fan speed based on a cable connection includes reading an identifier (“ID”) of a network interface card (“NIC”) installed in a computing device, the identifier indicating a NIC type, determining one or more cable types connectable to the NIC from the specification information of the NIC, and measuring power consumption of the NIC. The method includes determining from the power consumption the one or more cable types connectable to the NIC a current cable type connected to the NIC or a lack of a cable connected to the NIC, determining power requirements for the NIC based on the lack of a cable connected to the NIC or the current cable type connected to the NIC, and adjusting a fan speed of one or more fans of the computing device in response to determining the power requirements for the NIC.

Abstract: Systems and apparatus for controlling light emitted from light sources that backlight multicharacter keycaps, resulting in different characters being displayed on the keycaps. A system may include: a processor, and a keyboard having one or more backlit keyboard keys, where at least one of the one or more backlit keyboard keys includes: a socket comprising a light source, and a keycap coupled to the socket. The keycap may include: a first color filter corresponding to a first character, where the first character is displayed on the keycap when a color of light emitted from the light source matches the first color filter, and a second color filter corresponding to a second character, where the second character is displayed on the keycap when the color of the light emitted from the light source matches the second color filter.
