Is it possible to have a HDMI PORT installed in a laptop which doesnt have a HDMI port?

It would be MUCH cheaper to get an HDMI adapter for one of your other ports. For example you might have a DVI or mini-DVI port. Keep in mind though that DVI is video only.

If you only have a VGA output, you can get a converter box that can covert VGA output to HDMI, but your laptop likely will not support HD resolutions.
