Q: My Macbook Pro 13" is Running Ridiculously Slow

For Lex...

I believe the battery is going out, but if I do not have to replace it I am fine having a power cord hooked up to the computer. It took me about 30 minutes to get this post up because of the Rainbow Spinning Pinwheel... any help is much appreciated!

Thank you,

Daniel
