Pentalobe screw sizes include TS1 (0.8 mm, used on every iPhone starting with the iPhone 4s), TS4 (1.2 mm, used on the MacBook Air and the MacBook Pro with Retina display), and TS5 (1.5 mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for the Torq-set screw drive.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
In the most basic of circuits, if the current falls below the holding current even briefly, the circuit is turned 'OFF' (becomes blocked). However, complex circuits and devices may have different delays built-in between the time the current falls below this level and the time the device turns 'OFF'.

The MacBook is thinner than its predecessor, the iBook G4, but it is wider than the 12-inch model, and has a widescreen display. 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.
As part of the Mac transition to Intel processors, Apple released a 13-inch laptop simply named "MacBook", as a successor to the PowerPC-based iBook series of laptops. . During its existence, it was the most affordable Mac, serving as the entry-level laptop that was less expensive than the rest of the Mac laptop lineup (the MacBook Pro portable workstation, and later the MacBook Air ultra-port
Aperture is the sum of setup and hold time. The data input should be held steady throughout this time period. [28] Recovery time is the minimum amount of time the asynchronous set or reset input should be inactive before the clock event, so that the data is reliably sampled by the clock. The recovery time for the asynchronous set or reset input ...
Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...
