Blinking Battery Light when fully Charged - why?

Received my new dv800z CTO notebook last Friday. I've been playing around with it and generally checking it over. I seem to have either a battery issue, power mgt driver issue, or some kind of hardward issue.

When the battery is being charged and it reaches about 97% full, the battery charge light starts to blink. It will blink for as long as the notebook is plugged in once it starts. According to the HP documentation, a blinking light indicates a critically low battery charge. On top of this, when fully charged, the power meter never goes above 97%. When discharging, the notebook will shut its self down due to a low battery condition when the meter reads between 30% and 40% charge.

I don't think it's the battery as the run time actually seems reasonable - over 2 hours (though I didn't time it exactly). I did use the battery check routine on the HP web site and the results came back normal for the battery. So what could the issue be; bad AC adaptor or driver or ??

PS - also checked for driver updates from HP and none were offered.

 

Just thought I'd circle back and update this post. After troubleshooting the issue with HP support, turned out to be a bad batter pack. They shipped me out a new one no charge. Received it in about 2 days from authorization. I did have to send the old one back and they wanted my credit card number in case I didn't return it.

By the by, I'm getting a little over 3 hours use out of the new battery. That's doing basic stuff like web surfing and word processing with brightness set to about 2/3 rds full.
