Hello I'm going to purchase a Dell Inspiron E1705 online, and I'm a bit confused about the power adapters. The confusion comes when I reach the step 3, there you can choose accessories for the notebook and there I see that:

 

Select options below

 May ship after your Inspiron E1705  May ship after your Inspiron E1705

And I come to wonder if I don't purchase any of theese, will my notebook come with any power adapter at all ? If not then why choosing a power adapter is in the section of the accesories after it's reqiured to plug my notebook in the outlet whether to charge the batter or just use the notebook when the battery is low.

So the question is: do I have to purchase one of those stated above or the notebook will come with whatever power adapter ?
