That's about to prove real handy.  Kirk Bastek found himself with that most vexing of Chromebook woes, the missing serial number. Kirk writes: Some days, I even impress myself. We have a few chromebooks from CDW-G that do not have Serial Numbers printed on them. A web search brings you to developer mode, but you can not do that on a managed device, which these are. Have your Google Admin Console open to manage devices and you will see a them listed by the day they last synced but before that you will see enrollment day. That's what you're looking for.

Run the recovery tool and tell it which Chrome device you're building a restore image for.  Open the Chromebook you want to recover. If you...

​When you start changing policies in the Admin console, the day will come when you may struggle to remember whether the current setting is one that you inherited from the domain, or one you set yourself.  All Policies by default are Inherited from the master CPS policy, and, if you look for it, default, inherited, policies have a special flag that says so.
