I've just recently had a problem with my battery. Sometimes after putting it to sleep hours later the computer will just shut off and not see the battery until I pull it out and put it in a couple of times. Also, when I push the button to check the charge, none of the lights come on, but when I get the computer to finally see it it's all charged up. I'd appreciate some advice on this...

Now the computer keeps showing the battery at 0% and charging, or if I switch to time indication it will continuously say "calculating..." but make no progress
