Yes. The premiums depend on the value of your laptop, what kind of coverage you want and what your deductible is.
I'm no insurance expert but I'd say you have two different options:
1) If you were to buy a BTO (built-to-order) laptop like Dell or Gateway they offer their own "covers all insurance". I know that Dell offers this and I believe it's $349 for 3 years and covers everything but theft.
2) Get special insurance from a company which specifically insures laptops or a general insurance company like State Farm, Allstate, Farmer's, etc.
