This way, though, it is impossible to protect a laptop from professional thieves, but at least it makes amatters falter. A small lock with a cable tie to the table leg will make you feel more secure. This Kensington solution costs $ 30.
More "lock"
If Kensington's solution is not "big enough", you can use Belkin's "bigger" lock for $ 24.
Alarm bell
Just like an alarm system for cars, this solution only helps when you are near the laptop. Belkin's USB alarm system ($ 55) will ring an alarm when the cable connected to the computer is disconnected.
Motion sensor
The Doberman's $ 30 solution incorporates a motion sensor, which alerts you when the computer is carried away.
Software recovery service
If a thief has "sneaked" your laptop, you can still use this service to find out where to hide them. The cost of these tracing services is different (Lojack - 50USD / year, PC PhoneHome - 30USD / year, Inspice Trace - 30USD / year, Laptop Tracker - 40USd / year, and zTrace Gold - 50USD / year) but They all have in common that they are able to connect to the central server and alert the owner of the hidden laptop, and then report it to the police.
BitLocker (for Windows PC)
This hard drive encryption solution helps protect personal information and important financial data stored on your laptop. When stolen these encrypted data are almost impossible to decrypt. Windows Vista Enterprise and Ultimate versions are equipped with BitLocker to enhance the security of these operating system installations.
FileVault (for Macs)
Mac also has its own hard drive encryption software called FileVault with functions similar to BitLocker.
