Yes, and No, Tracking devices for mobile phones can be used if you are concerned that your laptop will not have an active data connection when it is stolen. This means that even if there is no wifi signal present on the computer or network being used then tracking software should still work through GPS triangulation showing its last known location before going offline. Usually, this lasts up to 24 hours after disconnection from a wireless device. However, apps like Prey offer free online access so in theory anything with wi-fi connectivity could be tracked using their services. There are also many other third-party applications available but these non-official websites may contain viruses or malware so be careful when downloading them from unknown sources.
