Compaq laptop monitor broke cant see anything on laptop monitor, so I bought a new hp external monitor to use. When I plug it in to the VGA port on laptop it states no signal....and cant install monitor software d/t I can't see laptop monitor. This may not be as hard as it seems to me, but I don't have a clue how to do it. Any help please?

Some laptop external video ports have to be enabled (or toggled on/off) by Using a Function Fn Key + F? Key sequence. Check manual or keycap.

you could always take apart your laptop and disconnect the built in LCD cable from the motherboard. It would then default to the external monitor.

I do this when I am troubleshooting laptops.
