Bottom lid of laptop shorting motherboard and can't power on

[50]

Hey guys,

I'm wondering if anyone can weigh in on some advice here. I have a Asus UX31 ultrabook with an all metal shell. I noticed it wouldn't turn on yesterday and so I opened it and tried disconnecting the battery then turning it back on. It turned back on, but then when I put the bottom lid back on, it wouldn't power on at all again. I realized something is shorting to the chassis and tried cleaning the lid and pushing down any stray flex cables to no avail. I'm considering putting masking tape all on the bottom of the lid, but am not sure about heat and whether the tape will hold long term. Anyone have any ideas?

Check the lid switch, some laptop have a switch sensor that put the laptop to sleep when closed.

Check the lid switch, some laptop have a switch sensor that put the laptop to sleep when closed.

That switch can also be set to do other things, including nothing. This is usually found in Power Management. I have to assume OP means "bottom OF THE lid," and not "bottom lid." I have never seen a laptop with two lids - top and bottom.
