Not getting a warning before my battery's dead...
I'm no longer getting a notification that my battery's dead and my MacBook just shuts down... Any ideas what I could do?

First, reset SMC.

Then calibrate the battery.

If there is no improvement once you've done both these steps, it's also possible that your battery has reached the end of reliable useful life and simply needs to be replaced.
