While most capacitors are rated for hours of operation at °C their expected design life roughly doubles for every °C below this. At °C a lifetime of years can be expected. This appears reasonable for a computer motherboard however many manufacturers have delivered substandard capacitorscitation needed which significantly reduce life expectancy. Inadequate case cooling and elevated temperatures easily exacerbate this problem. It is possible but tedious and timeconsuming to find and replace failed capacitors on PC motherboards it is less expensive to buy a new motherboard than to pay for such a repair.citation neededMotherboards are produced in a variety of sizes and shapes form factors some of which are specific to individual computer manufacturers. However the motherboards used in IBMcompatible commodity computers have been standardized to fit various case sizes.
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 due to the large number of integrated components. Almost all medium to high end Nvidia cards and most high end ATI cards support the technology.Prior to the advent of the microprocessor a computer was usually built in a cardcage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires in very old designs the wires were discrete connections between card connector pins but printedcircuit boards soon became the standard practice. The central processing unit memory and peripherals were housed on individual printed circuit boards which plugged into the backplane.
