Poor PF for laptop adapters?

I just got a kill a watt. I quickly tested all of my machines (they idle around 45-55W). One surprising observation was my Dell laptop adapter registered a PF of about 0.55. Is this typical for laptops? I assumed that since they are international voltage that they'd be high to satisfy EU reqs (unless laptops are exempt or they happen to be fine at 240V?) My two desktops measured around 0.96.
