Case:
Customer laptop has been used normally before, and suddenly unable to turn on, so I took the laptop maintenance station for maintenance. The inspection found that it was a hard disk failure. The customer’s hard disk data was very important, and the data was urgently needed to restore the data.
Solution:
The customer’s notebook is Seagate 320GB hard disk. After power -on, it is not transferred to the hard disk. It is suspected that there is a problem with the hard disk circuit board. Check the hard disk circuit board and find that there is a burning phenomenon. The judgment should be damaged by the hard disk circuit board.At the same time, the BIOS chip on the original damaged circuit board replaces the BIOS chip on the new circuit board (replacing the BIOS chip to identify it normally). After the replacement is completed, the hard disk can be identified normally, and the customer data is intact.
