Rapid battery decline after turn off/turn on

30 min. ago I turned off my MBP with battery 98% charged. Went to work, turned it on and now it's 2% and charging. WTF happened? Anyone experienced the same?

Maybe your battery is dead. Has it happened before?

Never happened before. But I doubt it's dead, because it's charging as usual.

Maybe the MBP didn't went to sleep and something was bogging down the CPU?

Check the Console for hints.

Thanks, but I didn't put it to sleep, I shut that thing totally down.

Still the Console might help finding out what happened in that time, though I am a bit perplexed to be honest.

Just checked it, there are no messages between SHUTDOWN_TIME and BOOT_TIME. Don't know what else to look for, I'm not an expert in this.

What you can do now is unplug the battery and to a SMC reset. Sometimes, the SMC goes wild and drains the battery while the computer is shut down. If this doesn't work, time to invoke AppleCare.

Thanks for the hint, that's a possible option.

Battery is fully charged now. Btw, iStat Pro says battery health is 98% (63 cycles). Everything seems ok for the moment, maybe I'll do some tests later.
