What your old laptop OS was is called an OEM version. It only works on it's own hardware.
So it wasn't supposed to work. What other OS do you have?
I just bought a 310 lenovo ideapad laptop.It didn't come with an OS so i installed my old fujitsu laptop's windows 7 dvd.Now in Control Panel\System and Security\System in manufacturer part it says "fujitsu technology" there is a fujistu logo and there's nothing about lenovo.Is this a problem?
ps:When installing win 7 i formatted and deleted system partition by mistake.
