The memory slot of 1. motherboard is damaged. This kind of fault is not very common. Generally, the motherboard of Sony wmex52 1 is deformed, and the memory slot is damaged and cracked. When we insert the memory into the memory slot, there will be some poor contact. When the host fails to pass the power-on self-test, there will be a continuous and short "beep" sound, which is usually called "memory alarm". For the deformation of Sony wmex52 1 motherboard and memory stick, we can fix the memory stick with a cable tie after it is inserted, supplemented by gluing.

2, memory gold finger oxidation. This situation is most likely to occur, and it is generally seen on machines that have been used for more than half a year. When the weather is wet or the weather temperature changes greatly, the machine will work normally yesterday, but when it is turned on the next morning, it is found that it cannot be turned on normally, and the display screen is black, and only the "beep" sound in the machine can be heard. If this happens only occasionally, it is not worth making a fuss about. Simply remove the chassis and reinsert the memory module.
