Run ASD and see if any error pops up.
Or install HWMonitor and check temperatures.
You can also try another BIOS file; no ME issue possible, as it is not iCore machine.

so the board suddenly start normally, tested all function, its normal.
is there any componen intermittently working ? is there anything I should check?

History : the customer came 1 week ago with his own charging port and battery, requesting us to install it for him, and then a few days later his macbook got trouble like I mentioned above

I doubt you can diagnose a good working machine...

Run ASD, just in case; probably no errors, if machine works good now.
You can also test it with different chargers.
