Without further details, I remain unconvinced of true hardware security. By hardware I would presume they mean a system/keyboard controller - one that can monitor events, delay and toggle privacy mode. A controller that likely has updateable firmware and could be compromised via SW given sufficient effort (TLA, Dell, &c). The privacy mode might be unsubvertible via SW, but I wouldn't take their word for it.
