[Solved] Won't boot automaticly when power is provided

#1

I bought 2 rockpi X.
One of them, when I provide it power, it has green and blue light (both not that bright). And in one second, the blue light goes bright, as if it is booting. Then in about 2 second, the blue light goes off, as if it is in OS.
But it is not. There are no output in HDMI. Short press the power button won’t do anything. I have to press the power button a little longer, about 2~3 second to get the blue light goes on and then bright again, then the OS boot.

Another one does boot once power is plugged, but after I somehow long pressed the power button to shutdown the OS, it also won’t boot automatically, just like the above mentioned one.

How can I make my RockpiX auto boot again?

Solved. It seems to be some BIOS settings or status. I restore defualt in BIOS settings, it didn’t help. But after I remove the CMOS battery and wait for some minutes, both board will power on once powersupply is plugged.

把BIOS设置恢复默认没用，但是拔掉CMOS电池，等一会儿，插回去，就可以上电启动了。
问题解决。
