Failed IC in a laptop. Wrong input polarity has caused massive overheating of the chip and burned the plastic casing. Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause.
Acer is recalling six models of laptops after reports of short circuits that could cause users to get burned, the U.S. Consumer Product Safety Commission said. A wire that goes to the internal ...
[11] [12] Personal computers cooled in this manner may not require either fans or pumps, and may be cooled exclusively by passive heat exchange between the computer hardware and the enclosure it is placed in. [12] [13] A heat exchanger (i.e. heater core or radiator) might still be needed though, and the piping also needs to be placed correctly.
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
Thermal Design Power (TDP), also known as thermal design point, is the maximum amount of heat that a computer component (like a CPU, GPU or system on a chip) can generate and that its cooling system is designed to dissipate during normal operation at a non-turbo clock rate (base frequency).
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 ...

In laptops, the LCD's backlight also uses a significant portion of overall power. While energy-saving features have been instituted in personal computers for when they are idle, the overall consumption of today's high-performance CPUs is considerable. This is in strong contrast with the much lower energy consumption of CPUs designed for low ...
