thanks guys but i  visited osx86 wiki and was not able to find this laptop in the portable compatibility list moreover would i get all the drivers and all the hardware working after i  hackintosh??

unless you have the ati video upgrade, and ur 1555 is with the intel gma x4500, ur hackintosh would be poor, as no QE/CI support would exist. those are needed to further enhance the mac experience

my studio has ati hd4570 gpu 512mb would it help??
