Dale's computer maintenance center
Dale's laptop is small, highly integrated, easy to use, etc. Unlike domestic electronics such as televisions and discs, laptops are not used in a fixed environment. Each component of the laptop is made as compactly as possible for ease of transport, which to some extent increases the probability of a laptop hardware failure. Hardware damage due to heat dissipation and physical damage due to inappropriate use (e. G. Impact, fall from heights, etc.) are highly likely to occur. In addition, poor inter-component contact as a result of excessive movement is a frequent failure。
(1) hardware failure on the master plate
The main panel of the laptop is relatively less likely to fail, including external force damage, ageing of electrons on the main plate due to excessive use time and electrical failure due to dust, dirty or damp。
(2) hardware failures of memory, graphic cards and other extended cards
There are two main failures in memory, graphic cards and other extended cards: loose between the card and the slot, and poor exposure due to oxidation of dust, stain or plug. Also, for suitable cards with high power chips, such as graphic cards, the burning of components or software failures (such as black screens, dead machines, etc.) due to heat dissipation are common。
(3) hardware failure of cpu
Cpus for laptop computers are less likely to fail than for other components, and frequent failures are often caused by heat dissipation or hyperfrequency, inappropriate set-up, etc。
(4) optical, software hardware failure
Optical, soft, additional equipment for laptops and consumables. The frequent use of optical or soft-reading cds or diskettes... Can cause laser-head or magnetic-head stains and ageing over time. However, optical and soft failure is usually easier to judge and generally does not affect the operation of the entire laptop。
(5) hard drive hardware failure
Hard drives are very important data storage devices in laptops. With the development of digital storage technology, the hard disk volume of laptop computers is becoming smaller, and data access is increasing faster, as is data storage capacity. In addition to heat-dissemination malfunctions, exposure to vibrations during high-speed operations is highly damaging to physical damage, while light results in poor data storage, which in serious cases can cause disk damage and affect the use of hard drives。
(6) hardware failures of keyboard, mouse, touchboard
For keyboards, mouse, touchboards, long use, too big buttons, dirty, etc. Can cause malfunction. Usually, the mouse is more likely to fail; while keyboards and touch boards are less likely to fail because of their integration with laptop computers, often due to external stress pressure。
(7) hardware failure on screen
The laptop display is integrated with the host. In order to keep the laptop as small as possible, the screens are generally made of liquid crystallized materials and wells are designed in a pendulum. For screens, external force oppression and injury are more difficult to repair. In addition, the lcd screen has been in use for too long, and poor displays due to the ageing of the lamps around the lcd screen are also frequent failures of the display screen. The breakdown of the internal connection line as a result of wear and tear is also one of the failures as a result of frequent overlays。
