can detect a suspicious condition:
- Excessive login attempts (local). Multiple failed login attempts in a pre-boot authentication (PBA) screen.
- PBA login timer expires (local). If the user does not log into the PBA screen successfully within the IT-specified time frame, the laptop enters theft mode.
- Rendezvous timer expires (local). A local, hardware-based timer expires if the laptop does not check in with the central server within an IT-specified interval of time. This feature is a local trigger implemented in hardware; it works regardless of network connectivity.
- Notification from server (remote) via IP-based network. A flag set in the central server triggers a poison pill, which is sent to the laptop via a wired or wireless LAN the next time the system checks in.
- Notification from server (remote) via 3g-based network. IT administrators can automatically or manually send a poison pill via an encrypted SMS text message over a 3G network.5 This allows IT administrators to remotely and rapidly trigger a lock down even without LAN/ WLAN-based connectivity.
- PC tampering (local). A lock down can be triggered when Intel AT detects changes in the firmware of the laptop or removal of the CMOS battery.
