>Heck my first laptop had a second LCD to show battery level without the machine even being on Many modern laptops still do this though. Dell XPS had some LEDs on the side and a button on the case that when pressed would light up the LEDs as a percentage indicator of battery charge, and my 2 year old Lenovo has this feature built into the motherboard EC controller and Bios that when I press any key on the keyboard when the laptop is OFF, it wakes the laptop's own display to show battery percentage. Modern laptops have many neat features.
