I had to open my MacBook Pro (2010), to replace the DC-In power cable and when I was closing it back up, in error I ripped the Battery indicator Flex cable, and now the machine won't power on at all, I've tried SMC, holding down the power & every other trick I have come across on Google, I'm wondering if it simply won't power on because that cable is missing, or if in my repair I ****ed something else up. I have already ordered the replacement cable and should be here within a day or two.
