Asus X200MA can not be restarted

[cyngo]

I have problems with asus x200ma rev 2.1
if in power on an interval of about 10-15 seconds the screen will appear and then restarted from windows the screen blank.
I've done flash bios, replace EC, reball singlechip, but the problem remains the same.
as a comparison of other asus X200MA with normal conditions, if on power on the screen immediately appear. then restarted no problem.
is there someone having the same problem? and is there a solution?

Thanks before

I hope you have kept backups of the original Bios and EC dumps. Clean the ME region in the original Bios dump. It may solve the problem. If you do not know how to clean it, upload the original Bios dump here. Then, someone will clean it for you.

I've replaced the bios and EC ic from other asus x200ma with normal condition, but no change.

have you discovered any other symptoms on this laptop? sometimes, disconnecting harddisk and removable devices may solve the problem.
