Which one to repair (battery or power source or logic board)?
Having a 15" MBP i5/2.4GHz system for 3 years. Last night I disconnected the power source and carried the laptop 5 feet while it is running to connect to HDTV using the mini display output. As soon as I put the laptop on the floor (carpeted), it started making a huge noise and noticed the OS X is started doing the indexing. Since this is common as whenever OS X does the indexing it utilizes the whole CPU and memory, it makes that noise. I knew it. So left it a while. 5 minutes later connected the power source as trying to watch the movie from laptop to TV. The noise continues and I don't see the battery information in the menu bar or even in the settings. It says the current battery charge level is 0%. When connected the power source, the green light is very dim (vs very bright in normal case and switches to orange/red color while charging) and doesn't change color to orange/red indicating that it is charging. When pressed the little soft button on the left side of the laptop which shows the battery level, doesn't show anything at all. Restarted the machine few times and still no luck. Next day morning tried the Hardware test as mentioned by Apple (holding down the D key while system is starting), but nothing came out of it. The system started normally, didn't even get the hardware test screen. The noise still continues and this morning I don't see even the dim light (green) when the power source is connected. The system starts and runs normally but makes noise. Even if I disconnect the power source, the system is still ON. But battery charge is 0% as per the OS X settings. How is this possible? Initially I thought the battery is gone. But seems like something else now. Please suggest me what to do here before even going to any repair facility. I really appreciate the experts help in this matter. Let me know if you require any additional information.
Please let me know which one to replace based on what I explained above.?

Is this a good question?
