If the hardware of the machine is abnormal, it is recommended that you send the machine to the service station at your convenience, so that professional engineers can actually check the machine for you to see if the hardware and other hardware are normal.
For information about the cost of hardware maintenance and replacement, if necessary, you can contact the service station in advance to consult relevant information and prices. Service station query:/Lenovo/WSI/station/servicestation/default.aspx.
