Re: Serial Numbers
"So, anyone who even had half a clue (or even a quarter of a clue) should have known that turning in a laptop with a different serial number would, eventually, ring all sorts of alarm bells"
In theory, yes, but in practice many items go missing, are broken, replaced, etc. It would be unlikely to be an unusual event that would "ring alarm bells" in most environments... In my last environment we had dozens of devices (across tens of thousands) report as missing from the asset database each month.
Also with laptops, by their nature they might not appear on the network for a long time, so how do you know they are actually missing in any brief timeframe?
