Open Question: acer laptop with built in memory card reader?

my g/f has a acer laptop with a built in card reader, I am trying to get it to read a sdhc card. I dont know where to go in the computer itself to read the card reader. I have everything setup to auto start upon connecting. It is windows 7. My only other that is it's suppose to read sd cards but, if it doesn't actually say it reads sdhc cards, then it won't read it probably right?
