You can run a remote desktop server or VNC server on the laptop, and connect to it from another computer over the network. However, it's going to be difficult setting it up if you have no way to actually see the laptop's GUI. Connecting the HDD to another PC would be about the only way, but that only works about 10% of the time in my experience, and all the new drivers Windows will automatically install if it works will degrade its operation when you put it back in the laptop.
