laptop stolen from car – will landlord's home owner's insurance cover it? auto insurance doesnt…?

My car was broken-into and my mac was stolen. I had taken comprehensive auto insurance, but they say that auto insurance wont cover items lost due to vandalism and that it will be covered by home insurance. I live in a rented place and so dont have homeowner's insurance. Would the landlord's home insurance cover it, since the item belongs to the home that is owned by the homeowner?

The most qualified people to answer this question are the people your landlord is insured with, NOT people at yahoo.
Why not ask them and be done with.
