laptop power switchover: common feature?

[nomail1983]

Since my company selected my laptop for me (with
MSWin XP Pro SP2), I do not know which features
are common among all laptops and which features I
need to ask about when I purchase my own laptop.

I am particularly interested in the laptop power
switchover. With my current laptop, I can switch
between AC and battery simply by plugging in and
unplugging the AC connector at any time. The power
switchover does not affect any running applications,
networking (esp. wireless), or Windows.

(By default, the screen brightness is reduced when
I run on battery. But I can override that.)

Is that feature common to all laptops (running MSWin
XP SP2 or later)? Or with some laptops, do I need
to do one or more of the following: (a) exit
applications first; (b) log out first; (c) restart
Windows; and/or (d) power off and on the computer?

Does it differ depending on whether I have XP Home
or XP Pro?

If it is not a standard feature for everything and
I need to ask about it, what do I call that feature?

I would call it "seamless power source switchover".
But that's just me.

No ,it doesn't.Windows XP Home is almost the same as Professional.
