Looks like my soon-to-be 8 year old MacBook Pro is toast. :( I took it for battery replacement, after that it has had issues with #configd / #powerd processes spinning up, using all the battery, and locking up programs. Took it back to them and they replaced the battery again, but the same issue persists. I've tried everything I've found online and reinstalling the machine but no dice.

New laptops are so expensive. :S
