Question
How long do I keep the papers about a laptop taken on holiday?
Keep the papers about a laptop taken on holiday while the thing they describe is still insured, and for a year after that. A receipt is worth most at the point where nobody can remember the year any more.
Away from home a laptop sits under a different heading from the one that covers it at the desk, and the two amounts are not the same.
The serial number is on the base and in the system settings. Written down before a trip, it takes an hour out of everything that follows.
