THe Combo can do everything except Burn BluRay disks. The other one can burn the blu ray.
I tried to attach pictures, links to show you but I haven't a clue what I am doing. But in essence. According to Dells help me choose stuff, the combo will burn CDs/DVDs and play CDs/DVDs/BluRay disks. The OTher will burn all 3 and also play all 3.
Blu Ray DVD -/+RW....watch bluray, burn bluray, watch DVD, burn DVD, load sofware from DVD, listen to CD's, burn CD's, load software from CD's.
Blu Ray combo...all of the above EXCEPT burn BLURAY discs.

Yes, it is someone confusing, that's why I listed exactly what it says....clears it up, kind of like mud...:smileyvery-happy:
As far as the charger. With a laptop you get an Ac Adapter (usually 90W) that is used to power the laptop when it's plugged in and also charge the battery at the same time. It is standard equipment, so you are all set.
