We all know that laptops will inevitably wear out hardware for a long time. However, hardware problems often do not appear at once, but appear as some small glitches. When these failures occur, many people don't know which part is the problem or how to solve it, so they ignore it.
In fact, when the computer has some signs, we should start maintenance, rather than continue to use it, until the computer is further damaged. The following professor will share with you the "signs before the damage of the notebook hardware", you can check against each other to avoid unnecessary trouble and loss!
The hard drive is damaged
If your computer is self-testing as soon as it is powered on, or the icon keeps spinning and stuck on the LOGO interface, it may be caused by an external device or hard disk problem. At this time, first unplug the external device, and then turn it back on, if the problem still exists, it is likely that the hard disk has failed.
In addition, when the program is running, there is a white screen, a black screen, a stuttering phenomenon, individual hard disk partitions cannot be opened, and there is a delay in typing, etc., which may be caused by hard disk damage.
The memory module is corrupted
If the computer often restarts automatically, the screen appears irregular and different colors when booting, or the blue screen + English letters appear when running the program, it may be because the memory module is loose or damaged, you can find a professional to help replace the memory stick to try.
The video card is damaged
If the screen is black after the computer is turned on, there is a high probability that the graphics card is damaged.
If there is a screen display after booting, but the screen color is not normal, the display is incomplete, the handwriting is blurred, especially when playing the game, the sudden blue screen, the stutter drop frame, the screen appears mosaic, etc., may be related to the damage to the graphics card.
In addition, it may also be a memory module failure, you can start with a simple memory memory module, eliminate the memory cause, and then consider the graphics card problem.
The processor failure
If the temperature of the fuselage is too high when the computer is running, sometimes it will automatically shut down, it may be a problem with the CPU processor, which can be detected by Master Lu.
There is also a case where the card is too slow to read large software/files, and it is often stuck because of an operation, waiting for a response of at least a few minutes, which may be a problem with the processor or hard disk.
At this time, it is recommended to add/change an SSD to try, if it does not work, then consider the processor problem. See how the processor occupancy is, is it in a high load state for a long time. If the occupancy rate is good, you need to find a professional to check the processor.
Keyboard failure
The computer appears to be a type string key, failure, no response, generally the keyboard is damp or damaged caused, followed by the possibility that the motherboard control keyboard chip is damaged, you can replace the keyboard to try.
The problem follows the battery or charger
If the computer charges slowly, the power is used up quickly, and the charge will be cut off from time to time, it is most likely a problem with the battery or charger.
In this case, first unplug the charger to see if the computer is working normally in the battery state, whether the power consumption will be too fast, if not normal, then consider the battery problem. In addition, it is also possible that the aging of other devices has led to increased power consumption, which is relatively rare.
If the computer works normally after detaching from the charger, try replacing a charger.
Nowadays, the mixed use of chargers is a common thing, but it is necessary to remind everyone in particular that the use of chargers by computers should pay attention to two problems: one is the matching of the charging protocol, and the other is that the charger power is not lower than the standard power of the computer.
This is because the regular charger has a built-in smart chip that can identify the device power and adjust the voltage, even if the charger power is higher than the standard power of the device, the charger can also distribute the appropriate current to prevent too high current from entering the notebook battery.
For example, using a "Greenlink 100W Gallium Nitride Charger" that is compatible with PD3.0, QC4.0 and other fast charging protocols to charge the "13-inch MateBook Air" that supports 65W power, the charger will recognize that the computer supports 65W, trigger PD 65W fast charging downwards, and charge 70% in 30 minutes.
However, if the computer is charged with a low-power charger, in the charging process, the charger needs to be in a full load state for a long time, which will easily lead to excessive heating of the charger and accelerate the internal loss, and will also accelerate the aging of the notebook battery.
Therefore, in order to maintain the battery, try not to charge a high-power computer with a low-power charger.
The above is the sign of notebook hardware damage shared today, if these "symptoms" have come to your computer, then check the number into the seat as soon as possible, maybe change a part, the work efficiency will be doubled!
