Yes, I do as well. While Shivani is correct that using it with a battery
avoids bringing in noise from the AC power lines and the laptop's AC/DC
transformer, you still have the noise from inverter which powers the
florescent backlight.

These days, there are an increasing number of laptops which replace the
florescent backlight with LEDs. These laptops (presumably) don't have
an inverter, and may be (or may not) be easier to tolerate.
