Hi. John. I think that is something in the manual from the old days that was never corrected. Even with the bn with the newer motherboard, you would never get 20 hours. The board used more power than the older ones. I hear the older boards could get 20 hours, but not the new ones and certainly not the MPower. I suppose humanware should correct this little oversight in the manual. I also saw a line in chapter 13 that went nowhere. It was half a sentence and then it went to the next section. At what point below ten percent does your battery die? Last time, mine died at around nine percent. Granted, I used the modem once, but that was it. I was playing with bluetooth last night trying to test some verizon phones and then I read for an hour. I went from 75 to 59 when I looked at it this morning. Before using bluetooth, I think I was at 89; so that short time of using bluetooth repeatedly dropped it from 89 to 75 within an hour or so of noncontinuous use.
Peripherals really seem to drain the battery quickly.

    Just out of curiosity, how much battery life should one expect from a BN
mower?  The manual suggests twenty hours, but I do not foresee this, even
without using cards and external drives.  Am I correct in assuming that it's
more like 10 or 12 hours or is my battery already messed up?  I've  used it
from 100 percent to under ten three times and granted that I have used a PC
card and wireless card at times, my estimations have been around the 10 to
12 hour range in total life.


Thanks

Hi, Carol. I agree. Probably not worth sending the unit in. Just more of an
annoyance. I still can get it charged to 100 percent and as long as you know
the battery dies at just under ten percent, you know what to expect.
Also,
losing that ten percent means that you will not get 10 to 12 hours of use
out of an MPower. Again, not a big deal as long as you are aware of it. It
just means you have to charge up more often.
It would be nice if these guys would come out with a car charger or some
kind of external battery charger.
