do you have a working power supply to test or a power supply tester
are you using a video card or onboard video?

Is your VGA cable correctly mounted?
Check the pins aren't bent or broken.
Is the VGA cable working to begin with? Can you test with another.

What's PTs regular display? I would like you to take pictures of both the ends of the VGA cable up-close so that all the pins are clearly visible, and upload them

On a laptop you usually have a Function icon on one of the F keys sometimes F4 sometimes F12, but you need to hold down the Function (Fn) key when pressing the correct key.
The Function icon should look either like a square box with a vertical line either side
or
a laptop with a monitor screen next to it.
What brand of LT is it?
Example; Samsung R510
