Some computer designs have used non-button cell batteries, such as the cylindrical "1/2 AA" used in the Power Mac G4 as well as some older IBM PC compatibles, or a 3-cell nickel–cadmium (Ni–Cd) CMOS battery that looks like a "barrel" (common in Amiga and older IBM PC compatibles), which serves the same purpose. These motherboards often have ...
This is often called the CMOS battery or BIOS battery. The original IBM AT through to the PS/2 range, used a relatively large primary lithium battery, compared to later models, to retain the clock and configuration memory. [2] These early machines required the backup battery to be replaced periodically due to the relatively large power consumption.
Steve Jobs introduced the MacBook Air during Apple’s keynote address at the 2008 Macworld conference on January 15, 2008. [4] The first MacBook Air was a 13.3-inch model, initially promoted as the world's thinnest notebook at 1.9 cm (0.75 in) (a previous record holder, 2005's Toshiba Portege R200, was 1.98 cm (0.78 in) high).
The MacBook was one of Apple's first laptops to adopt the MagSafe power connector (the first being the MacBook Pro), and it replaced the iBook's mini-VGA display port with a mini-DVI display port. The iBook's discrete graphics chip was initially replaced by an integrated Intel GMA solution, though the latest revisions of the MacBook were ...
The M1 13-inch MacBook Pro was released alongside an updated MacBook Air and Mac Mini as the first generation of Macs with Apple's new line of custom ARM-based Apple silicon processors. [114] This MacBook Pro model retains the same form factor/design and added support for Wi-Fi 6 , USB4 , and 6K output to run the Pro Display XDR . [ 115 ]
The Apple–Intel architecture, or Mactel, is an unofficial name used for Macintosh personal computers developed and manufactured by Apple Inc. that use Intel x86 processors, [not verified in body] rather than the PowerPC and Motorola 68000 ("68k") series processors used in their predecessors or the ARM-based Apple silicon SoCs used in their successors.

The 15-inch MacBook Pro weighs the same as the 15-inch aluminum PowerBook G4, but is 0.1 inches (0.25 cm) deeper, 0.4 inches (1.0 cm) wider, and 0.1 inches (0.25 cm) thinner. [7] Other changes from the PowerBook include a built-in iSight webcam and the inclusion of MagSafe, a magnetic power connector designed to detach easily when yanked.
