?? does the drive recognze cd, dvd and not blu-ray, or does not recognize any media??
When I googled your System found this:
quote: DVD combo, DVD+RW, Blu-ray® (need Broadcom Media PC card to support Blu-ray disc)
If problem is only with blu-ray, you may also need additional software to read Blu-ray that did not come with the system (ie you installed the Blu-ray drive.).
