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 ...
It is derived from I²C for communication with low-bandwidth devices on a motherboard, especially power related chips such as a laptop's rechargeable battery subsystem (see Smart Battery System and ACPI). [1] Other devices might include external master hosts, temperature sensor, fan or voltage sensors, lid switches, clock generator, and RGB ...
A review by the Tech Report of the pre-production 2012-vintage NUC found that the NUC would seize up after a few gigabytes were transferred over wireless and that the problem could be alleviated by better cooling of the NUC case. Intel later increased the default fan speed for production machines through a BIOS update (downloadable from Intel's ...
Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as central processing units (CPUs), chipsets , graphics cards ...

These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the ...
It corresponds to the total power drain from the direct current supply rails of the CPU. Rca (°C/W) = Thermal resistance of the Heat sink, between the case of the CPU and the ambient air. Tc = Maximum allowed temperature of the CPU's case (ensuring full performances).
