Will an SMC reset lose computer data?

I have a 13" whitebodied Macbook from 2007. Just recently, the battery appears to have lost the ability to hold a charge. It is a replacement battery that I purchased when the old one died. This battery is about 2 years old. The light on the Magsafe is constantly green, but the battery menu says, "Battery is not charging." If I unplug the Magsafe, the computer shuts off immediately. After doing a bit of research, it seems as though I might be able to "repair" the battery by doing an SMC reset. I would love to be able to do something this simple, as long as I do not lose any hard drive data. It would also save me from purchasing a new $129 battery! So, two questions:

1) Is it true that I could do an SMC reset to potentially "repair" the battery?

2) Will I lose any data on my computer's hard drive when I do the SMC reset?

Thank you!
