Every laptop is different. If you unplug your AC power adapter from the laptop and it start it up, then your battery is doing the work. If you want to check the opposite, remove the battery and make sure the AC power adapter is plugged in properly and start it up. If your laptop starts up from one form of power but not the other, either your connection is bad or the hardware itself (ex. battery or AC power adapter) is faulty.
