Go here and download the IMSM (Intel Matrix Storage Manager) and install - you could also install the chipset software firstly (9.1.1.1019) REBOOT then the matrix(8.9.0.1023) REBOOT - hope this works for you - AHCI is enabled in your bios, and what happens during installation of Windows 7 is Windows 7 installs the Intel
driver, but for correct functionality you need to install the intel matrix storage manager after installation is complete if you dont it will cause the problems with the DVD DRIVE.
This isnt your exact model as i couldnt locate it on the USA site if you live in another country try it, but this product has the same
drivers - if it wont install and leaves a message the system hasn't the minimum requirements you dont need it in any case. These
drivers are intel
drivers and work for all Intel chipset laptops and will work with yours if you have a bios that supports AHCI. I could of directed you to intel download centre, but its not working correctly at the moment.
