The southbridge typically implements the slower capabilities of the motherboard in a northbridge-southbridge chipset computer architecture. In systems with Intel chipsets, the southbridge has been named I/O Controller Hub (ICH) and later replaced by Platform Controller Hub chipsets. In older Intel/AMD architectures the southbridge is usually ...
The Power Management Unit (PMU) is a microcontroller that governs power functions of digital platforms. This microchip has many similar components to the average computer, including firmware and software, memory, a CPU, input/output functions, timers to measure intervals of time, and analog to digital converters to measure the voltages of the main battery or power source of the computer.
Laptop computers generally use highly integrated, miniaturized, and customized motherboards. This is one of the reasons that laptop computers are difficult to upgrade and expensive to repair. Often the failure of one laptop component requires the replacement of the entire motherboard, which is usually more expensive than a desktop motherboard.
Comparison of some common motherboard form factors (pen for scale) A PC motherboard is the main circuit board within a typical desktop computer, laptop or server. Its main functions are as follows: To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer
A motherboard, also known as main board, logic board or system board, and sometimes abbreviated as mobo, is the central or primary circuit board making up a complex ...
3.5" Floppy disk drive by Alps Electric with FRU number A field-replaceable unit (FRU) [1] is a printed circuit board, part, or assembly that can be quickly and easily removed from a computer or other piece of electronic equipment, and replaced by the user or a technician without having to send the entire product or system to a repair facility.
Haswell featured a FIVR.. Most voltage regulator module implementations are soldered onto the motherboard.Some processors, such as Intel Haswell and Ice Lake CPUs, feature some voltage regulation components on the same CPU package, reduce the VRM design of the motherboard; such a design brings certain levels of simplification to complex voltage regulation involving numerous CPU supply voltages ...
