I was looking at many possibilities as to why my USB ports stopped working, and after talking to a few people they mentioned that my power settings may be causing them to stop working, but what if the laptop battery was no good and unable to hold a charge like it should. Could that cause the USB ports to stop working?

Yes.
Many USB devices when connected actually drain power so one of the best power saving techniques for laptops after dimming the screen and throttling the processor speed back, is to start shutting power-hungry sources off such as USB ports, wireless, etc.

So would that happen even if it was plugged into AC power?
