@thomasfuchs that PowerBook g4 was my first work laptop that replaced my desktop, the battery is a spicy pillow but I think it still boots with the power brick. One of the best of the era, it had every port built in, the screen res is low by today's standard but I used it for sysadmin work for years and years of until my boss forcibly replaced it with an Intel macbook. Nice keyboard and touchpad too
