Quick maintenance of HP zhan66 plug-in power supply and black screen shutdown

This machine forum and online have not been found yet.blueprintReferring to the rescuer’s fault of the same type, the resistance value of the voltage divider is abnormal when the line is locked and the CPU is powered on. The voltage of a single battery is 1.2V, and it is about 1.8V when it is plugged in. After replacing a set of resistors, the voltage is 1.2V when plugged in, and the machine returns to normal. In order to facilitate the quick maintenance of this fault, we hereby mark it. Of course, this fault has ruled out other power supply problems.
