   The second image shows the same laptop failing to operate properly due to the aforementioned graphics card defect, crashing the operating system and displaying a blue screen of death (albeit with graphical artifacts) on the screen.

4. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air ...

   The turn down ratio depends on the system configuration and manufacturer. It modulates from 15 or 25% up to 100% at full capacity with a single inverter from 12 to 100% with a hybrid tandem. This method is the most efficient way to modulate an air conditioner's capacity. It is up to 58% more efficient than a fixed speed system. [citation needed]

6. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance; this causes large voltage spikes, which may exceed 500 volts. A broken metallisation on a chip may thus cause secondary overvoltage damage. [1] Thermal runaway can cause sudden failures including melting, fire or explosions.

7. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   This "control air" system responds to the pressure changes (due to temperature) in the control tube to activate heating or cooling when required. The control air typically is maintained on "mains" at 15-18 psi (although usually operable up to 20 psi). Pneumatic thermostats typically provide output/ branch/ post-restrictor (for single-pipe ...
