When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
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 ...
Computer maintenance is the practice of keeping computers in a good state of repair. A computer containing accumulated dust and debris may not run properly ...
One pin receives the timer restart ("kick" [a]) signal from the computer; another pin outputs the timeout signal. A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), is an electronic or software timer that is used to detect and recover from computer malfunctions.

In many computer installations, it is only enough time on batteries to give the operators time to shut down the system in an orderly way. Other UPS schemes may use an internal combustion engine or turbine to supply power during a utility power outage and the amount of battery time is then dependent upon how long it takes the generator to be on ...
In computers, heat sinks are used to cool CPUs, GPUs, and some chipsets and RAM modules. Heat sinks are used with other high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light-emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its ...
An active laptop cooler. A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers intended to reduce their operating temperature when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related ...
