Chemical reactions involving thermal runaway are also called thermal explosions in chemical engineering, or runaway reactions in organic chemistry.It is a process by which an exothermic reaction goes out of control: the reaction rate increases due to an increase in temperature, causing a further increase in temperature and hence a further rapid increase in the reaction rate.
The Dell Inspiron series is a line of laptop computers made by American company Dell under the Dell Inspiron branding. The first Inspiron laptop model was introduced before 1999. [ 1 ] Unlike the Dell Latitude line, which is aimed mostly at business/enterprise markets, Inspiron is a consumer-oriented line, often marketed towards individual ...
2006: Sony notebook computer batteries recall: Worldwide: August 2006: Dell recalls over four million notebook computer batteries, after several instances where the batteries, made by Sony, overheated or caught fire. Most of the defective notebooks were sold in the US, however, some one million faulty batteries could be found elsewhere in the ...
Applications such as aerospace systems, life support systems, telecommunications, railway signals, and computers use great numbers of individual electronic components. Analysis of the statistical properties of failures can give guidance in designs to establish a given level of reliability.
The dust buildup on this laptop CPU heatsink after three years of use has made the laptop unusable due to frequent thermal shutdowns. In operation, the temperature of a computer's components will rise until the heat transferred to the surroundings is equal to the heat produced by the component, that is, when thermal equilibrium is reached. For ...
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 battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. [15] All radios, except crystal sets, used inconvenient and messy vacuum tube batteries until the mid- to late-1920s. Battery eliminators that plugged into light sockets became very popular. [16]
An uninterruptible power supply (UPS) takes its power from two or more sources simultaneously. It is usually powered directly from the AC mains, while simultaneously charging a storage battery. Should there be a dropout or failure of the mains, the battery instantly takes over so that the load never experiences an interruption.
