Here’s a series of pictures on laptops and what can happen from heavy use. Knowing the laptop has been assigned to the IT department and is heavily used, this type of use is normal.
The plastic grill can become brittle from heat if the computer has a virtual computer (Server 2012, SQL Server and development software). The touch pad can actually show wear from a developer who uses the laptop hours on end.
The final picture shows how lint can fill the heat sink and why the CPU should be pasted annually.
So is the laptop abused? No. Annual maintenance should be performed on any laptop to free the heat sink of any lint. A grill can be made from stainless screen (future post).
