Yes there is a schematic, I can search for it , or maybe on sorin-s forum , aniway It seems that my M11X died in similar way , Plug'ed in a "so called SSD, internal slot" , and it not post anymore. I wen't trough flashing the bios , and it complete's but no success after. The key combo to activate the Phoenix Crisis Recovery on the M11x is simply pressing the "END" key while plugging in the A/C cord . And it beeps confirmation after finishing (read's from USB tumbdrive).
Opened up the M11X , and found a few stuff wrong inside , was missing something at GPU lvl , SMD mounted that and reflow-n it , but southbrige heat's up (more than it should) , and Not enough voltage after power-up to GPU (reads 1. someting or 2.v nowhere near enough , so maybe a busted vrm also) , I just gave up for now . Was unable to determine the corect procedure to fix it , (it beeps so bios seems fine , but blank screen , fan's loud - that's it).
