Generally speaking, computer failures include hardware damage and software program errors. The former is a hard fault and the latter is a soft fault. Hard faults can be divided into three categories: equipment faults, mechanical faults and man-made faults.
Device failures are mainly caused by components, connectors and printed boards; Mechanical failures are mainly external equipment errors, such as keyboard key failures; Man-made faults are mainly caused by the machine not meeting the requirements of the operating environment or improper operation.
The faults of components themselves, such as capacitance expansion, explosion, black resistance, serious heating of integrated block, etc. It may be caused by overload, insufficient power supply or CPU overclocking, except for its own quality problems.
In general, the newly installed computer has a failure, which may be a hardware failure or a software failure, but the possibility of hardware failure is relatively high.
Sometimes, the failure of newly installed computers is often due to poor contact, such as poor contact of various cards, memory, CPU and so on. And the motherboard, or the power cable, data cable and audio cable are in poor contact.
Extended data:
Fuel saving breakthrough
1, ultra-high pressure injection technology: 2000 bar ultra-high pressure and efficient fuel saving technology, more complete combustion and lower fuel consumption.
2, speed control technology: unique intelligent speed control technology (LBSC), fuel-efficient driving, low-speed gear shifting.
3. Lightweight and modular design: the engine parts (only 649) are less than 50% of the peers, and the self-weight of the whole vehicle is at least 8.5 tons.
4. Matching technology: the power system and the whole vehicle system are optimally matched, and the low-speed economical fuel consumption speed of 1000 rpm has remarkable fuel saving effect.
5. Innovative fuel-saving technology for reducing resistance: low wind resistance and low rolling resistance for the side air intake system of the whole vehicle; Adopt electric control silicone oil fan, patented cooling, lubrication and air intake system is highly integrated, with low friction and low energy consumption.
Security breakthrough
1, engine braking technology: The unique IBrake engine compression braking technology improves the braking efficiency by 50% compared with the traditional in-cylinder pressure braking, the maximum braking force can reach 370 horsepower, and the downhill speed can reach 70 km/h, which makes the braking safer and more efficient.
2. Super steel plate: The car body conforms to European standard safety regulations, and the cab adopts 1MM high-strength anti-collision steel plate to ensure the safety of drivers' lives and property.
3. High-efficiency braking devices: American Kangmai front drum or full disc brake, ZF large-caliber steering gear, independent hand brake for tractor and trailer, etc.
4. Safety guarantee: the rearview system and lighting system are fully upgraded, ABS+ASR system, three-point adjustable seat belts, etc.
