I’m currently looking to buy myself a new laptop, as my old one (a dell xps 1530) has pretty much given up the ghost. I’ve got a total budget of about £650, but that needs to include a reasonable warranty.

I’m not looking for a world beater at all. I don’t use my laptop for anything particularly consuming – the biggest things for me are that I can watch films on it, that it runs smoothly even when I have a lot up on it etc. I don’t use it for games other than FOOTBALL manager, so a graphics card that runs powerful games isn’t at all necessary. A good battery life is a must.

I’d like either a lightweight 15’ laptop, or if not then a 13’. I love the bigger screen of my current one, but it’s unbelievably heavy (I have an extended battery thing as well) so something lighter weight would be wonderful.

I confess entirely that I know very little about laptops, and so have been looking at PC world’s red hot offers this week, going by the idea that the laptops that used to be EXPENSIVE and have now come down in price are probably the best. On that basis, I’ve come up with things like:

and

Any suggestions, either about the laptops above or other good offers, are hugely welcome. Thanks in advance!!
Don't get anything with a Celeron processor. They're cheap for a reason.
You'll want a minimum of 4GB of RAM. Don't buy Acer or Samsung.

That's all the advice I have to give you. You can't really go wrong with laptops nowadays, they all pretty much do the same. I'd recommend HP, Dell or Asus but you're already familiar with all those brands.
