I bought my HP Laptop in Dec 2011, less than a year, and the battery is no longer taking a full charge - only about 85% even when left on the charger overnight.
Q: Does that mean the battery needs to be replaced? And is that normal lifetime?

Our Dell laptop battery stopped charging probably because we had it constantly plugged in. Batteries don't last long if they're not allowed to use their charge. So, we bought a new battery for the Dell, and now our 17-inch laptop goes for about 4-5 hours before losing a charge. Quite a bit for such a large laptop that has so many bells and whistles!!
Do you periodically unplug your computer to let the battery wear down?
Seems like it's still new enough that it wouldn't start having that problem so soon.

am thinking maybe my practice of plugging the laptop into the charger every night may be the issue. SO am going to let the battery go FLAT/DEAD and then recharge.
Anyone here agree that's a good plan?

I allowed the battery to go completely flat - left it on the charger all night - and it still only charged 85% - ratz and double ratz!
Nelson,
I'm not sure about this, but I don't think I would be as concerned with how highly charged the battery registers on the internal meter. It is really just an estimate of how much charge is left. The key capacity to understand is how long it will actually run your computer. Does it seem that your computer runs at least 15% shorter on a charge? (all batteries lose their capacity over time- mine began by lasting almost all workday long; now it will last all morning or all afternoon- I've had it for just over 2 years) If it seems to run about the same as when it said it was charged 100%, I would not be concerned.
I find that the best practice is to only plug in my laptop when it needs a charge. I let it run down as close to zero as I can and then fully charge it. I have been running my laptop this morning from a full charge for about 2.5 hours. It says that I have 1 hr 22 min (44%) left. I'll plug it in until it is fully charged and then unplug it. I try very hard not to leave it on the charger overnight or for other extended periods.
It may very well be that your battery is fading fast. That does happen. I would hope that it would last more than 10 months, though. In the end, I think I would be more concerned with how long it will run on a charge than with what the meter says.
