Did the laptop die, or the hard drive?? If the drive is dead, you obviously won't be able to mount it.
You don't say what version/distro of Linux you're using, but most Linux distros these days, can mount Windows partitions in at least read-only mode. The ntfs-3g stuff is usually present, and can be loaded with a 'modprobe' command, if it isn't already. Read the man page for mount, but "mount -t ntfs <device name> <mount point>", like "mount -t ntfs /dev/sdc1 /media". Make sure the mount point directory is there, and you may have to be root to issue that command.
Make sure you get the right /dev id. Disconnect the windows drive and boot. Do an 'ls /dev/sd*' (could also be hd*, depending on your distro), and see what's there. Shutdown, plug in the Windows drive, and boot up again, and repeat the ls command. You should see the new devices, each one should have an entry...if you've got two partitions, and it's the second drive, it'll probably show up as /dev/sdb1 and /dev/sdb1.
Another cheap thing to try, is to get a USB external enclosure for the drive. They're pretty cheap (probably about $25 or so), and make the laptop drive an external, USB/Firewire device. Just plug it in, and it should automount, just like any other USB flash drive.
