Working Toward a Universal Power Brick For Laptops 365

An anonymous reader links to PC Authority with some hopeful news about untangling a persistent annoyance for laptop users — namely, the myriad power supplies called for by laptop makers: "'On a PC, an ATX power supply for example will screw into certain mounting holes, have a maximum size and shape, and will take a standard 3-pin "kettle cord" for incoming power. If it complies with these standards, the PSU will be able to bolt into any manufacturer's ATX case.' Laptop design, on the other hand, involves cramming a PC into a tiny chassis, which usually has its own thermal design and power distribution requirements. This has led to the somewhat bizarre situation where every manufacturer has its own laptop power supply design. It now appears that some of the major players in laptops are getting together to work on a standardized laptop power supply design. Not only are big players involved, but the IEEE (Institute of Electrical and Electronics Engineers) has created a team to work on the power supply standard."
