Plug the device into a wall charger for 2-4 hours and then see if it will boot. Running the battery down past 205 can harm a lithium battery, especially if done more than a few times. So it could very well be a bad battery. If plugging into a wall charger doesn't work, I wold try a replacement battery.
Some versions of the OS will shut the device off when hitting 20% of battery life to protect it.
When plugging into a PC, you need Desktop Manager installed, which also loads the proper device and charging drivers. When plugging into your Mac, make sure you are using a powered USB. And when plugging into any PC or Mac, plug directly in the the machine, do not connect via a HUB. BBs ad HUBs do not get along very well.
