I have a broken laptop. How can I access the information stored on the hard drive?

I have a defective HP Pavillion ze5400 laptop with a Hitachi Travelstar 75gb hard drive inside. This laptop is broken and will not power up. How can I access the data of this drive on my newer HP Pavillion dv6000 laptop?
