Treatment method of power adapter fault
- Oct 20, 2017 -

Now, the power adapter has been integrated into our daily life and work, we can use it everywhere, such as the emergence of the problem with more naturally, so we need to master the method of solving the trouble today, let the power adapter manufacturers of professional introduction analysis and processing method of power adapter specific failure for everyone, we then look down:

Now the computer generally uses the ATX power adapter, when the system fails, from the BIOS, power adapter itself and the motherboard and other aspects of a comprehensive analysis. According to the computer maintenance "after the first soft hard" principle, we should first check BIOS settings are correct, because false failure caused by improper setting of exclusion; the second step, check the ATX power supply is normal; the third step, check whether the normal power monitoring circuit board.

In determining whether the power adapter is normal, the power can be disassembled, with a scrap equipment (such as hard disk, etc.) false load, so as to avoid no-load protection. A 100~150 ohm resistor is inserted between the PS-ON signal line (green) and the ground wire to turn the signal into a low level. If the power supply can work, the fault is displayed on the motherboard or BIOS settings, otherwise the fault is in the power supply itself.

The power adapter plays the role of power source in the computer system, and its normal operation or not is the key prerequisite for the normal operation of the computer system. But in the daily maintenance of the computer room, found that the power adapter and other computer components, but also there will be a variety of faults.
