Any frequent traveler like myself will tell you you're playing with fire leaving valuables like a laptop in a checked bag. Checked bags are lost ALL THE TIME, stolen from all the time, and damaged even more. If you're lucky, your travel insurance may throw you a bone for the value of the laptop but they won't be able to replace the value of what's on it. I won't even get into how disruptive it will be to your business trip or vacation to have a missing laptop.
Rule #1, avoid checking luggage at all costs. Rule #2, if you are forced to check, don't put anything in there except clothing, sundries, and other things of little value.
