Computer power supply maintenance and repair
Generally speaking, the sound of the computer during normal operation is very low. not considering the sound of the hard disk reading and writing data, it is mainly the sound of the cooling fan, especially the sound from the switching power supply fan. Some switch power supplies will generate some noise during operation after long-term use, mainly due to poor rotation of the power supply fan. There are many reasons for the noise of the power supply fan to rotate, which is mainly concentrated in the following aspects:
-- The fan motor bearing sleeve produces an axial deviation, causing the fan blades to get stuck or rubbed, causing a "bump" sound.
-- The fan motor bearing is loose, causing the blade to make a "beep" sound when it rotates.
-- The fan motor is axially swayed. Due to the wear of the gasket, the axial clearance increases, and the sound of "burst" is generated after power is applied.
--Inferior lubricating oil is used in the fan motor bearing. When the ambient temperature is low, it is easy to condense with the dust entering the fan bearing, which increases the resistance of the motor rotation and makes the motor emit a "beep" sound.
If the fan does not work properly, it may burn the motor after a long time, causing damage to the entire switching power supply. For the reason that the above power supply fan makes a sound, the following maintenance work is usually required.
The power box is the easiest place to collect dust. If the sound from the power supply fan is loud, the fan is usually removed every six months to clean the dust and add some lubricant for simple maintenance. Since the power supply fan is sealed in the power supply box, it is not convenient to disassemble, so be sure to pay attention to the operation method.
(1) Fan removal First disconnect the power of the main unit and unplug the input and output cables behind the power supply. Then unplug and connect all the accessories connected to the power supply, remove the fixing screws of the power supply box, and take out the power supply box. Observe the appearance of the power supply box, remove the screws reasonably and accurately, and remove the cover. When taking the cover, pull the wires out of the gap at the same time. Remove the four screws that secure the fan and remove the fan. You can not solder the two power cables temporarily.
(2) Cleaning the dust After using the cardboard to isolate the power circuit board and the fan, wipe the dust with a small brush or a damp cloth and wipe it clean. It is also possible to use dust from the fan to blow fan blades and bearings.
(3) Adding lubricants Tear off the self-adhesive labels and pick out the rubber seals with needle-nosed pliers. When you find the motor bearing, add lubricant and push the fan by hand to make the lubricant flow evenly along the bearing. Usually add a few drops. Pay attention to whether the fan of the ball bearing has two bearings. Don't neglect the oil feeding to the bearing on the air inlet surface. Do not put the oil on the main shaft.
Lubricants must use computer-specific lubricants or advanced lightweight sewing machine oils. Never use lubricants used in general automobiles. Finally, install the rubber sealing sheet and label it.
(4) If the fan sends out a large "burst" noise, it is generally impossible to solve the problem by cleaning the dust and lubricating oil. When the fan is disassembled, the axial sliding distance of the fan blade is found. Big. After taking out the rubber sealing piece, use a needle-nosed pliers to separate the snap ring on the shaft. Below is the gasket. At this time, the fan rotor can be taken out (connected with the fan blade). The original gasket is used as the standard, and the thin plastic sheet is made of moderate thickness. Make a gasket. Put the prepared gasket between the original gaskets, pay attention to the gasket not too thick, and keep a certain distance in the axial direction. By turning the blade by hand, the fan can rotate smoothly. Finally, attach the snap ring, rubber seal and label. Remember the small parts on the main shaft, rubber seals, springs, etc., so as not to know how to reset.
In short, the power supply is the driving force of the computer. If the power supply fan fails, the consequences are serious. Therefore, the power supply should be maintained and maintained regularly.
According to the data, the fault caused by the power supply accounts for about 20% to 30% of the total number of failures of various components of the computer. The fault detection and maintenance of all parts of the host must also be based on the normal power supply. Below we will discuss some common faults in the power supply. Microcomputer power supplies are generally prone to the following faults: the fuse is blown, the power supply is not in the transmission or the output voltage is unstable, the power supply has an output but the power is not displayed, and the power supply load capacity is poor.
