Battery Monitor Not Operating Correctly

I bought a Macbook Pro 13" in April 2012. [Brand new from the Apple store near Central Park, NY]

Two days ago, the battery and its various monitoring levels have begun to act up.

Right now on the menu bar - the battery icon has an X in it. If this does change to a battery percentage, the percentage will remain the same, at whatever level it starts at 53% or 77%. Everthing else on the menu bar is correct - time changes, etc.

If I unplug the power cable, the computer will power down on some occasions, and not on others.

Now the green light (for fully charged) is showing on the cable. I just unplugged it and it did shut down.

When I pressed the battery indicator on the side of the computer, three green dots lit up.

My software is up-to-date. I have also noticed the computer running slower of the past few days too.

After less than a year, I wouldn't expect this to be a problem. Has anyone had a similar problem?

I'm now in the Republic of Ireland, and unfortunately we have yet to have an Apple Store open here, so there is no Genius Bar that I can bring it too.

Any help that anyone might have, will be extremely appreciated.

Welcome to Apple Support Communities. We're all users here.

First, try an SMC reset, as detailed here:

Since you mention both battery and performance slowdown, that might cure both issues.

PRAM doesn't often cause the problems you mention but a PRAM reset is detailed here, because people often do both:

And your battery may need calibrating, after the SMC reset:

And if none of this helps, the battery is likely failing. Even though there is no Apple Store, there is probably an authorized Apple dealer or repair center near you. When I searched from the US, this link appeared: http://www.apple.com/ie/contact/

Another cause of decreased performance is that your hard drive might be getting full. Do you have less than 10% free space? If you recently upgraded to OS X 10.8 Mountain Lion and you're trying to run it in less than 4GB RAM, that may also be responsible for loss of performance. But neither of these issues should cause the battery problems you mentioned.
