Asus K72F laptop won't start

[Reicher]

Hi, I have an Asus k72f that was originally running slow so I was going to open it to clean it. I didn't even get the case opened fully, put it back together, and now won't turn on at all. It came on the first time but after a few seconds it turned off. Now it stays off and won't come on. Any suggestions?

test your power supply

I have 2 power supplies and both don't help. Actually, when I plug them in, the charging light doesn't even come on

sounds like a dead motherboard

Just from opening it up?

Maybe when you open your laptop you disconnect the power board inside.

How do I reconnect that?
