hp 4510s < how to activate windows 7 on it?

hello
well i have a downloaded window 7 ultimate 32 bit. it works ok on my desktop and on my cousins desktop. It’s already activated when the installation is complete for desktops. But after doing the install on my cousins laptop hp 4510s, it says that i need to activate it and after 30 days it will stop working. Why won’t it work there? Is there some trick to activate it?
any pointers are welcome…
regards.
