In addition, check whether the CPU is working normally. After the instance is started for about half a minute, manually touch the CPU fan's heat sink to see if the temperature exists. If there is a temperature, the possibility of CPU failure can be basically ruled out. If there is no temperature, sort out

The next step is to check whether the fan is rotated. If the fan is rotating, the main power input must be working. If the fan is not rotated, either the fan is broken or the master power connector does not receive any current. Check whether the connection is disconnected, adjust your multimeter to a voltage level higher than 220 volts, and then tes

Here, we use an example in our daily life to demonstrate the implementation of the adapter mode. The specific scenario is: in our daily life, the electrical plug we bought has two holes, however, the outlet we bought only has three holes. At this time, we hope that the electrical plug can be converted into three holes, so that we ca
