Please take note that this is my initial suggestion for Windows 7 driers for this model, any feedback will help others too. So if you have problems and anything that useful please leave your comments.
NOTE: Please, do not install the drivers if its already work on your laptop, example after install windows 7 you already can use wireless and play musics, SO do not install AUDIO and wireless Drivers.
