What about my case? I tried different bios but the problem still same, no reaction after pressing power button...
the notebook is taking approximately 69mA , does this indicate to a mec firmware issue??

it depends if you already tried the bios flashing but same issue , you to look for other issues

Well , I tried different bios even the last one that you already posted, but the issue remains same. No reaction at all after pressing the power button.
Besides the notebook is charging fine , all power rails are present, 3.3v on the power button, as well.

The only thing that I didn't try, is flashing Mec1633 IC, because I don't have a such programmer.

Let's wait for other to shid light

[Ariu]

Thank you, still waiting for response from someone who was faced with this kind of issue and solved it.
