That is true, you may need to run it through several "full charge" cycles initially to set it for future use. Sadly, I don't think it's fixable if you did that already though :(. That is what I think as well.
When I purchased my laptop I used it straight up but apparently you had to charge the battery to full capacity before using it. I am not sure if it is still an issue anymore but it damaged my battery which can now only last 30 - 45 minutes before shutting down. :wacko:
