I think your going to find pretty much every person has differing views towards manufacturers. I much prefer Dell to anything else, as I've never had a problem with them and always got very good deals. If it was my child, I'd be building her a Dell online and getting it shipped.
Just make sure you get a multi year warranty, and if you have the option, include accident damage as well.
Set yourself a budget before you do anything. Extra's like Microsoft Office, a USB mouse and a printer need to be budgeted for too. Once you know how much you can spend you can then look for suitable models.
Have a look in your local newsagents/local shop and see if any of the laptop/pc magazines are doing monthly laptop reviews. These will help you in your search also. You can of course ask here, as many members will be able to tell you what they are like for warranty issues, but ultimately most of it goes down to personal preference.
Another very serious consideration is the degree/college course being studied. A law course wouldn't require a massive specification laptop as its mainly office task based, but if its 3D/graphics design, or music related, you'll need a higher specification laptop, and dependant on course, it might even be wise to consider a Macbook/macbook pro.
