You will probably lose unless you pay for a lawyer that has experience with this.
The problem with the law you quoted is it is written as such that the burden of proof is on you, not Johnny Law.
Since this part pertains to you,
"or video signal that produces entertainment or business applications, is operating and is located in the motor vehicle at a point forward of the back of the driverís seat, or is operating and the monitor, screen, or display is visible to the driver while driving the motor vehicle."
Let's examine that.
1, you do have a display in your view, in the front seat. And, it is freakin huge. Not likely to convince anyone it is an original Garmin jumbotron GPS.
2, even if you do convenience the judge that your laptop can't produce video playback, you still have that nagging verbiage "entertainment or business applications". Did you remove all of those possibilities too?
3, the location of your display is hardly in front of you, or on the windshield. Nor is it a 5" GPS screen, or an 8" OEM nav display.
IMHO, you are not going to win. But, good luck to you, and I hope you do win.
