I don't see your particular laptop listed as being compatible with that drive, and it doesn't list Win 7 as an OS it's compatible with either.
Not really sure if that matters or not, it might work with your laptop just fine, but it would suck if it didn't.
This one is a little more money but says it works with Win7 and will still burn DL discs if you need to.

I'm sure you can find cheaper ones out there or maybe one on NewEgg or something offering a rebate.
The one you posted might work fine, like I said. But, I don't have Win7 and don't know for sure.
Good luck!!
