If the laptop has no HDMI on it then getting a VGA lead is your only option.
You will also need a separate audio lead as well as the VGA lead only caries Video, not audio. exactly which audio lead you require will depend on what the PC audio input is on your TV, but you'll either need a 3.5mm jack to 3.5mm jack lead... Or a 3.5mm jack to 2 x RCA (phono) plugs.
(I bet curries told you to buy a stupidly expensive HDMI lead as well.... anything over about £5 for a shortish HDMI lead is a rip off)
