Speaking from my experience at my former eployer (a F500) we used all HP laptops across the entire org and our help desk staff were HP certified repair people.

Speaking from my experience at my former eployer (a F500) we used all HP laptops across the entire org and our help desk staff were HP certified repair people. So, when we had issues with our hardware we would drop it off at the help desk and they could do a lot of the repairs that sending the machine back to HP would get us.
