laptop wont start after putting new thermal paste on

[Mikeattax]

I just replaced the thermal paste on my Asus ROG Strix G531gt I made sure everything was plugged in before closing it and reassembling. i was following a tutorial on how to do it by a creditable source. and when i was done i tried to boot it up and nothing, i tried to force restart with holding power button and nothing the lights turned off but nothing else came on.

Take some pictures of the laptop with the back off, so we can see if you missed a cable or have something in wrong.  Just an upside down ribbon cable, one not plugged in, or one partially plugged in could cause this.

I would say to double check the battery cable, and make sure the back is on all the way (intrusion detection and such)
