Good game for a low-end laptop?

Lie, you wouldn't be able to play Left 4 Dead 2 at stable performance with that Laptop. Unless playing at 10-20 framerate is acceptable for you.

This is not a gaming Laptop, there are very few decent games you can play at decent performance. Old games like Diablo 2 or Warcraft 3 will work fine on your Laptop but you should have gave examples of what games you enjoy playing as there are endless amount of games out there.

What kind of game? Check gamerankings.com or steam for older games with good reviews. Steam even lists system requirements. They're pretty cheap too and they have a holiday sale going on right now.

Only detailed 3D games should give computer problems.
