Macbook Pro Won't Power On

[DingleGuy]

Hello, I have a 2007 pro and I recently installed a new hard drive and now it won't power on. It powered on just fine while it was apart with the old drive in it but now nothing. Any ideas what's going on or what I did.

Thanks

Like nothing happens when you press the power button?

If so, I'd make sure you put it back together correctly. Possibly the power button isn't connected (not sure if it goes through the keyboard or not) or the battery isn't seated right.

Did you even install OS X in the new hard drive?
