Abstract：In this paper, the failure of VELA? ventilator to enter the system was analyzed to provide reference for such failure. Such
failures, which did not go into repair mode and fail to observe error codes, were the trickiest and most difficult to analyze. In view of the
above faults, the main board circuit structure was analyzed in detail, and the main board was modularized according to its functions. According to
the actual start-up process, the fault point was judged. Through the actual failure case maintenance of our hospital, we expounded how to
solve the problem in detail, and the repair rate was low. Therefore, this method is feasible and stable for such failures, and it also has good
ductility for other embedded motherboards.
