Alternatively you can remove the laptop battery and use it with just the charging cable attached to power the device. The laptop will automatically shut off when the power cable is disconnected. Then PAM Duress [0] can be used for the xkcd538 [1] situation.

I guess it depends on the threat model, but if the primary concern is theft couldn't AC adapter disconnect be used for this?
