also do you know if your laptop is upgradable to other graphic cards? your laptop manifacturer should say that because some laptops can and cant be upgraded to newer alternative graphic card. (check manual)
not sure.... how to check when no manual given.... mine is Acer Aspire 5585WXMi I saw same model but they using Geforce card which is why I got it when i saw it but I dont get it why when I received the good, they gave me lousy card
after researching I saw that your brand of laptop may have discontinued in the series and it does support multiple graphic cards including NVIDIA. ask your store to see if they have the geforce 6600 and can upgrade for you because it will be safer for them to upgrade for you
