@Chironjit_Das You may try to decode the POST code using the Insyde BIOS documentation that can be found here.
I don’t know why it is not included with the official doc, or why it’s not easily available from Insyde’s website itself, but the link I sent should do it.
Are you sure it’s the bit 1, and not the bit 0, that is blue for you? You mentionned it was the first blink of the second sequence, so I would have thought “bit 0”, but do you see a green blink just before that blue one?
