How dusty was the system when you first opened it up? Did you check the GPU MXM board?

A common issue in this series is the GPU board fails and depending on how it fails it can short out causing your single diagnostic LED to blink.

Are you a hard user of the system? Running heavy graphics like large photo or video editing, video rendering or gaming? This system series can’t handle most of this.
