Problem looming with MacBook Pro Late 2008?

Question

This morning I had some ominous occurrences with my Mac Book Pro.  When I got it out, the battery was quite warm, even though I had turned it off last night before connecting it to the charger.  (It's never warm when it's not using the battery.)  Then, when I pushed the power button, nothing happened until after several pushes.  Eventually it did start up and seems to be working OK, but I'm worried, could this be a sign of a problem?  I lost a hard drive a few years and don't want to repeat that trauma.  Any ideas?  Thanks!
