That’s a reasonable step for troubleshooting no power. For additional clarification I would have a look at the [guide|151093|iFixit Battery Disconnect Guide|new_window=true] for this model.
If that doesn’t get your machine to power on, there’s also a [[MacBook Will Not Turn On|MacBook Won’t Turn On|new_window=true]] troubleshooting page that might help if you want to dig deeper once the bottom case is off.
Also, make sure to check your warranty before getting too far. These haven’t been out too much longer than a year, so it’s possible you might be covered by Apple.
