V440挂了，郁闷........
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。。。 最大化自检 节哀。。。换完电池重置时间了吗？ 本帖最后由 flutter 于 2014-08-25 15:18 编辑
:mrgreen: :mrgreen: :mrgreen: 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。 八成电源坏了，可以换一个试下，440电源应该两个绿灯才正常，而且开机很难发现电源问题，系统起不来就会电压不足宕掉 挂了，换个新的吧。我这有个闲置的机器。
