Abstract

The present invention relates to wirelessly locking a computer platform to discourage theft as the platform is transported in a distribution channel. A computer platform having a chipset, a random access memory (RAM) coupled to the chipset, a central processing unit coupled to the chipset, a protected storage device in communication with the chipset, and a wireless communication device coupled to the chipset is presented. A radio signal having an authentication lock is introduced into the wireless communication device. The authentication lock is then placed in the protected storage device. The computer platform is placed in the distribution channel.

Claims

1. In a personal computer, a mobile platform, comprising:

a chipset;

a random access memory (RAM) coupled to the chipset;

a central processing unit coupled to the chipset;

a protected storage device in communication with the chipset; and

a wireless communication device coupled to the chipset, the wireless communication device employs an open specification for wireless communication for data and voice.

2. The mobile platform of claim 1, wherein the protected storage is disposed within one of the chipset and the wireless communication device.

3. The mobile platform of claim 1, wherein the protected storage is coupled to the chipset.

4. The mobile platform of claim 1, wherein the wireless communication device operates at 2.4 GigaHertz.

5. The mobile platform of claim 4, wherein the wireless communication device includes frequency hopping every six milliseconds where the frequency hopping is bi-directional.

6. The mobile platform of claim 5, wherein the frequency hopping every occurs every six milliseconds and wherein the frequency hopping is bi-directional, the mobile platform further comprising:

a system non-volatile storage coupled to the chipset.

7. A method comprising:

transmitting a radio signal having an authentication lock into a wireless communication device of a computer platform having a chipset, a random access memory (RAM) coupled to the chipset, a central processing unit coupled to the chipset, a protected storage device in communication with the chipset, and the wireless communication device coupled to the chipset;

storing the authentication lock in the protected storage device; and

placing the computer platform in the distribution channel.

8. The method of claim 7, subsequent to placing the computer platform in the distribution channel, the method further comprising:

sending an authentication key to a predetermined destination; and

receiving the computer platform and the authentication key at a predetermined destination.

9. The method of claim 8, wherein transmitting a radio signal into the wireless communication device includes transmitting a wake event into the computer platform.

10. The method of claim 9, subsequent to transmitting a wake event into the computer platform, the method further comprising:

negotiating a handshake between the wireless communication device and the incoming radio signal.

11. The method of claim 10, prior to transmitting a radio signal into the wireless communication device, the method further comprising:

passing the computer platform in front of a radio signal transmitter.

12. A method comprising:

transmitting a radio signal having an authentication lock into a wireless communication device of a computer platform having a chipset, a random access memory (RAM) coupled to the chipset, a central processing unit coupled to the chipset, a protected storage device in communication with the chipset, and the wireless communication device coupled to the chipset;

storing the authentication lock in the protected storage device; and

placing the laptop in the distribution channel.

13. The method of claim 12, subsequent to placing the laptop in the distribution channel, the method further comprising:

sending an authentication key to a predetermined destination; and

receiving the laptop and the authentication key at a predetermined destination.

14. The method of claim 13, wherein transmitting a radio signal into the wireless communication device includes introducing a wake event into the laptop.

15. The method of claim 14, subsequent to tranmitting a wake event into the laptop, the method further comprising:

negotiating a handshake between the wireless communication device and the incoming radio signal.

16. The method of claim 15, prior to transmitting a radio signal into the wireless communication device, the method further comprising:

passing the laptop in front of a radio signal transmitter.
