    en.wikipedia.org/wiki/Memory_effect

    Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...

    A modern PC with a bus rate of around 1 GHz and a 32-bit bus might be 2000x or even 5000x faster, but might have many more gigabytes of memory. With boot times more of a concern now than in the 1980s, the 30- to 60-second memory test adds undesirable delay for a benefit of confidence that is not perceived to be worth that cost by most users.

    2-in-1s are often very thin, around 10 millimetres (0.39 in), and light devices with a long battery life. 2-in-1s are distinguished from mainstream tablets as they feature an x86-architecture CPU (typically a low- or ultra-low-voltage model), such as the Intel Core i5, run a full-featured desktop OS like Windows 10, and have a number of typical ...

  6. Instant-on - Wikipedia

    en.wikipedia.org/wiki/Instant-on

    In the past, consumer electronics manufacturers would emblazon radios and television sets with "Instant On" or "Instant Play" decals. In series filament sets, instant-on was accomplished by adding only a silicon diode across the power switch to keep tube filaments lit at 50% power; the diode was placed such that the typical half wave rectifier of the day was reverse-biased.

    This type of battery is also referred to as a lithium-ion battery [1] and is most commonly used for electric vehicles and electronics. [1] The first type of lithium battery was created by the British chemist M. Stanley Whittingham in the early 1970s and used titanium and lithium as the electrodes.

    Due to its portability, good battery life (and ease of replacement), reliability (it had no moving parts), and low price (as little as US$300), the model was highly regarded, becoming a favorite among journalists. It weighed less than 2 kg (4.4 lb) with dimensions of 30×21.5×4.5 centimeters (12× 8 + 1 ⁄ 2 × 1 + 3 ⁄ 4 in). Initial ...

    [14] [15] The ME also communicates with the host via PCI interface. [13] Under Linux, communication between the host and the ME is done via /dev/mei or /dev/mei0. [16] [17] Until the release of Nehalem processors, the ME was usually embedded into the motherboard's northbridge, following the Memory Controller Hub (MCH) layout. [18]
