You could possibly install a SATA-II 300 drive in your computer but it is unlikely you will see any performance difference. The rating for SATA-150 and SATA-300 refer to the burst rate at which data can be pushed across the SATA bus.
If your computer is only rated for a SATA-150 drive, your computer can only go that fast.
A SATA drive may physically fit in your laptop and may work, but the SATA bus speed will only be run at the rating of the controller on the motherboard.
The only other thing you can look for is a drive with a lower seek time and possibly a higher spindle speed with a SATA-150 connection. This may allow you to get some more "speed" from your machine.
Hope this helps,
