V440挂了，郁闷........

flutter

一台老机器，运行一直很正常。有一段时间报警，检查是：

MB/BAT         V_BAT         warning (0.59V)

于是，偶给它换了个主板电池，貌似一切正常

过了个把月，突然就挂了，无法开机。接上串口看看：

SC Alert: Host System has Reset

SC Alert: Host System poweron failed due to fault at MB.FF_POK

SC Alert: SC initiating soft host system shutdown aue to fault at MB.V_VCCTM.

SC Alert: SC Request ato power off host.

郁闷，看来无救了。。。

flutter

欢迎蜘蛛老大现身，偶看到了希望和光明，乌啦啦

1，偶是SUN菜鸟，不懂硬件，换完主板电池就完了，没有作时间同步

这个时间同步，如何作。。。。。。？貌似我做了NTP服务的，求指点。

2，现在如何自检阿，无论正常状态，还是自检开关状态，显示器根本无输出阿。

接上串口如下信息：


SC Alert: Host System has Reset

SC Alert: Host system poweron failed due to fault at MB.FF_POK.

SC Alert: SC initiating soft host system shutdown due to fault at MB.V_VCCTM.

SC Alert: SC Request to Power Off Host.

SC Alert: VOLTAGE_SENSOR @ MB.V_VCCTM has exceeded low soft shutdown threshold.

SC Alert: VOLTAGE_SENSOR @ MB.V_NET0_1V2D has exceeded low soft shutdown threshold.

SC Alert: VOLTAGE_SENSOR @ MB.V_NET1_1V2D has exceeded low soft shutdown threshold.

SC Alert: VOLTAGE_SENSOR @ MB.V_NET0_1V2A has exceeded low soft shutdown threshold.

SC Alert: VOLTAGE_SENSOR @ MB.V_NET1_1V2A has exceeded low soft shutdown threshold.

SC Alert: Host system has shut down.


我怀疑上次电池换得有问题，主板是不是彻底没有电了，所以无法开机。。。

求大神们给个思路。
