I have recently purchased a new laptop computer. I intend to use the
computer mainly as a desktop computer so it will usually be connected
to AC power. The manual states "Do not use your computer without
installing the battery pack as it may cause the computer to
malfunction"

However, the salesman in the Sony store advised me to remove the
battery for desktop use because it would extend the life of the
battery.

Why might removing the battery cause the computer to malfunction?

I remove the charged batteries from my laptops and store them in the
refrigerator. Every 6 months I recharge them if they have been unused
in the meantime.

Like most batteries their life is longer when kept cold.

As to why a Sony might malfunction without a battery, then I have no
idea. The Sony (and any laptop) certainly won't tolerate power
failures without a battery!

I hardly ever use my laptops on the battery. I've never had any
trouble doing this. I really buy laptops because they take up less
room about the place than a desktop does.
