Does my Northstar Laptop Need a New AC Adapter?
Northstar AC Adapters are are commonly referred to as chargers, bricks, adapters, power supplies, power adapters, and power modules. No matter what name that you use, the AC adapter’s job is to convert high voltage AC power from a wall outlet into a single low voltage DC source from which your computer can draw power. It is a common mis-conception that an AC Adapter is a battery charger. This idea comes from some of the first generation portable computers from the early 1990’s. This first generation circuitry was too big to fit into the computer, so some was placed in the adapter. This circuitry was quickly down-sized and by 1995 all laptops had the charger built into the computer. All modern Northstar laptops have all of the battery monitoring and charging circuitry built into the computer and battery. Many Northstar laptop owners with non-functional batteries look to replace the AC adapter because they believe that the “charger” is broken and it is usually a less expensive than a bat
