Try Neverwinter Nights. Your laptop might work it. You can try a demo first. It's made by Bioware and you can probably pick it up along with expansions for quite cheap. I got lucky and picked it up brand new on Amazon.co.uk for £2.00 (1p for the game, £1.99 for the shipping) and this was 2 years ago. My God, I would have paid full price for the game if I had knew about it back in 2002. You see, back then, I was strictly a console gamer and nothing more.
There is also Divine Divinity which is the first game in the Divinity series. Like NWN, it has a demo you can test on your laptop.
