it's not your laptop correct, it's your employeer's computer
if so, i'd report it to your IT department and let them file the claims through whatever insurance they have. they have more power than you do and would know the system better

if it's your own property,
making claims like asking for a travel voucher, etc would lower your chances of success IMO. I'd wonder why someone who actually values the property the lost would want a travel voucher or similar compensation instead of the replacement item or cash.

when AA lost my bag a few years back, they made me list out the contents (clothes) and then offered a standard replacement fee for the items. your credit card may also have some protection
