Laptop won't turn on unless plugged in

My laptop, Satellite A135-S4656, will not turn on unless the AC adapter is plugged in. It doesn't need to be plugged into the wall, just the port on the back of the computer. Once the laptop boots up I can unplug it and run off the battery, although the battery doesn't last very long either. If anyone has an idea about what can be causing this, I'd greatly appreciate it.
