I am trying to make a diagnosis to my X201s with strange power on issues.
(Detailed description of symptoms is in the X200/X201 section.

Can anybody tell me if this LCD ribbon cable looks normal or kind of "burnt"?

In a series of attempts I notice that the without HDD and RAM the MB sounds 1-3-3-1 ONLY if I press hard on the LCD connector.
