Asus K53SD: short when chassis is closed

[DS-1]

Hi guys,

I've changed the DC jack to a K53SD Asus mb. The new DC jack is working good, but when I close the chassis of the notebook (the upper plastic part) nothing happens when I hit the button), while if I lift up the plastic, the button makes the notebook starts.

What should I check according to your experience?

Thanks!

Does it apply enough pressure on the metal button when you press the plastic button?

This is not a question of pressure. If I sligthly lift it up and press the button, it turns on.

In addition, it is also possible that some metal section of the keyboard or the upper case makes contact with the mainboard. If so, cover it by some plastic tape. Probably, there is no other reason making such a short.

The issue was that the power button was covered with a conductive tape (it was used by Asus to put a part of the power button circuit to ground).

I removed it and now it works fine.
