Help::: Guitar Rig 4

hiiiii..m new to this forum.......
can ny1 tell how to connect my acoustic guitar with my pc so dat i can
get a good quality sound+i want to have the sound of mic also ????
????
???
:O

 

Ok. I think this has to be the right place to ask my doubt.
I am a guitar rig user and have been using it for years. Only so because my parents never entertained the idea of spending thousands on something that we all call a Processor. They never thought it was actually that useful compared to its size! So as an alternative I started to use G R. Everything was fine until my dad got transferred and he took my Computer along with him and left me with his Laptop.
Ok! So whats the Deal?
The deal is that my computer had a line in socket where my guitar cable used to go in. But this shitty Laptop which Im using right now has only 2 ports. audio and mic. I tried using the Mic input but It doesn't work. Only so as I googled to find that Mics do not have enough Voltage to get the guitar going. So all Im asking is for a solution to my problem... how do I get to connect my guitar to use guitar rig,or for that matter any effect modulating software. Is there anyone out there who can help me with this??
