No, it's an error. Many other devices using identical battery technology utilize a trickle charge to maintain a charge once it's fully recharged. The flaw in the 750 (and possibly other later models) is that they charge and then TOTALLY STOP CHARGING, allowing the battery to gradually drop down to aprox 90%, then charge it up again. Nobody is suggesting that the charging system NOT charge the battery. >If you are concerned about prolonging battery life, then you should not >store the battery in your machine while you are using it (I am a little >curious as to why you *do* store the battery in your machine if you >know it is troublesome, and have already destroyed batteries this way). While I concur that this is the way to deal with this problem, it's totally idiotic that I should have to remove the battery to prevent IBM's shoddy engineering from costing me $150. My $200 cell phone and $200 car mount has more intelligent technology in it. Also, leaving the battery in prevents brief power flickers from rebooting my machine, a real concern here in Florida during the storm season.
