That has happened on my 701 before, either when I got a new battery, or
sometimes it would do that and still last another 45-60 minutes!

Probably not.

The 755 is very similiar to the 355 and 360 machines, so I think that it
should be able to charge while in use.  The 355C that I have charges
while it's on, in suspend, and on.

I doubt it.  In fact, I think that 50W is sufficient for that machine.

Maybe it could be the temperature, humidity, or something like that.
Try a complete charge and discharge and tell me what happens.
