You could try using an dvi/hdmi adapter (if your laptop has a dvi I/O that is). You will have to check that your TV can accept a signal from a pc (not all can apprently), check your TVs documentation to confirm.
If it has a DVI output then as mentioned you can use a dvi to hdmi cable or adapter. If it doesn't, then you need a USB adapter to video out (VGA/DVI/HDMI). There are a few brands like Sabrent, Ultra, ArkView... here is one from EVGA: http/www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3184514&CatId=466
You would still need to use an audio cable from your headphone port out to the tv input (if you need audio).
