Hi! > With respect I have not seen a Laptop/Notebook with the 'Power Supply' > integrated on the motherboard since the days of 486's (Toshiba for example) > 'Power Supply' being the components that convert the AC mains from the wall > socket to the DC voltage required to run the Laptop / Charge it's battery. There's not a "whole" line voltage to DC power supply in a modern laptop, but there is very often a power supply known as a "DC-DC converter" that takes the single voltage from the power adapter and provides all the different voltages the computer will need. This supply usually also has the majority of the battery charging circuitry on it. Some (very few) laptops actually have power bricks that put out more than one voltage. I haven't seen any recent ones, though. William
