Case:
Customer’s laptop cannot enter the system, saying that it was a sudden blue screen during the normal use process. It was found to be a disk problem after the laptop maintenance office was detected.Inside, we need to restore the data, so I found us.
Solution:
This is a 10th generation disk. This sound is generally unavailable in the magnetic head. This sound is different from the sound of knocking (generally the sound of knocking on the plate is very bright, which is very small).The problem is locked in the following two places. One situation is that the circuit board causes insufficient power supply.Therefore, the circuit board was measured first to find that the motor IC output voltage was insufficient, and the performance was often jumping during measurement.After changing the circuit board directly, the sound of the “squeak”” sound disappeared
