warning

My MacBook Pro runs slower the longer it's on. I am getting kernel warnings.
Some, but not all, resets correlate with AC power connects and disconnects. I don't think the warnings do. (How do I tell?)
What are these errors? What causes them?
Can this damage the drive or corrupt data? What is it seeing that motivates these?
