how do you get that?

normally, the power consumption of the macbook is well under what the
power adapter can provide. however, it's possible that a peak burst
could momentarily push it beyond, in which case the battery will fill
the void until it drops back down. it's just a brief spike.

if there's no battery, it would shut off in that situation, which is
what they want to avoid, no matter what. users do not like when
computers shut down suddenly for apparently no reason.

the computer is designed to run with a battery installed, so this is a
huge edge case anyway.

depends what she does with it. since you say she's a writer, chances
are it will not come close to hitting peak power.
