Jean. You really should get at least ten before you get a battery low message.
If your unit is dying at 27 percent, something is wrong. Of course, you
could try calibrating the battery to see if this fixes the problem, but you
shouldn't have to calibrate a new battery. They are supposed to be
calibrated before they leave the factory.
I'd be talking to humanware on this one. Twenty-seven percent doesn't seem
right.
After writing this, however, I also need to say one more thing. If you are
using anything like a wireless card, the internal modem, bluetooth or the
USB ports, it won't be that odd to have the unit go flat at 27 percent.
What you want to do is to charge the unit all the way up to 100 percent.
Then just read, or type, or edit. Whatever. Just don't use any devices that
draw power. See if you then get to ten percent before you get the battery
low message.
If you do, everything is fine. Using wireless does drain the unit pretty
quickly and you might get the warning at 27 percent or even higher,
depending on how much you used your wireless card and for how long.
But if you are playing with wireless, etc, 27 percent sounds reasonable.
