MacBookPro not starting after removing battery/cleaning track Pad, etc
Some dust got inside the track pad of my new MacBook Pro 13" Model A1278 (bought brand new in May,2014). I followed a tutorial video of how to clean the track pad, which involved unscrewing/disconnecting the battery to get access to the track pad, disconnected the track pad carefully, cleaned it and replaced it, then replaced the battery. The MacBook was not connected to the MagSafe adaptor while doing this, the power was also turned off. There was about half the battery charge left when I began this procedure, which didn't take long to do. After connecting everything, and making sure it was as I found it, I screwed the back panel on again and pressed the power button to start up the MacBook, but it did not come on. I connected the MagSafe power adaptor, tried to power on again, and still nothing. It is dead. Although I noticed that the MagSafe adaptor has a very feint green light (nowhere near as bright green as it is when in good health). I am thinking that while removing the battery, using a small metal screw driver, I may have lightly touched the silver contacts that are beside the battery connector/plug for a split second. By doing this might I have short circuited the logic board? I joined another technical forum earlier today and someone said I may have done this. But could there be another reason I can't power up my MacBook? I hope someone can help. Thanks.
Is this a good question?
