Take the optimistic view of the choice of demonstration laptops. Maybe they 
chose a Lenovo because they wanted something that they though would be safe 
enough to use for a demonstration of blocked ventilation openings.

There is little information available at this time. Mr. Woodgate is correct 
that fire inspectors can misdiagnose the ignition source. I doubt the P.E.I. 
fire marshal will be able to determine the exact ignition source from a mass of 
molten plastic and charred metal. If the batteries ignited, the heat generated 
would likely destroy the best evidence.

The incident was less than a week ago and the investigation is likely not 
complete. The manufacturer of the laptop will likely want to get involved to 
determine if aftermarket power supplies or  batteries were used. Aftermarket or 
counterfeit batteries could be an issue here. Aftermarket batteries do not 
always fit properly. If the connector doesn't match correctly, arcing between 
the battery and computer could have occurred leading to the ignition of 
adjacent fabrics.

"P.E.I. deputy fire marshal Robert Arsenault demonstrates how vents on a laptop 
computer can be blocked when it is sitting on a pile of clothes. (CBC)"
Why did he pick that brand of laptop to demonstrate with?  XD

Does anyone have more information on this incident?

Blocked vent test anyone? Forseeable misuse? I like my computers well done.
