Working Toward a Universal Power Brick For Laptops
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."
It would be nice if they all standardized on a magsafe interface. Although I doubt it would happen, too expensive.
Regardless, this is great news. It would be very nice to have just 1 power brick for multiple devices.
At work we have a fleet of assorted laptops, and regularly have to go on a scrounge to find a power brick for someone who is visiting from another location who either left their brick at the other office/hotel/home/car and is running low on power
Or someone is issued a new laptop, and it only comes with one brick (which is semi-permanently tied to the docking station) and they need another for portable use. Why can't we use the one from their old laptop?
Even if it's the same manufacturer, the voltage or connector don't match. WTF?
If we need a second power brick, we don't reward the OEM with extra money. It's 3rd party for that (and usually cheaper too)

Good luck getting Apple to play along. While I prefer their design, I doubt they'd even license out the spec to other manufacturers.
Then we can just connect straight to car batteries.
Easy peasy charging in the car.
12V sealed lead acid motorcycle battery in your pocket for when the li-ion is failing after a year.
The broken-screen laptops we use as headless servers could have UPS for cheapness using old car batteries.
It would be awesome!
