Is there any way to find out when a Surface book was made, based on its serial number?
I am getting tomorrow my replacement book from Microsoft and would like to find that out. Thanks

Early on, people were keeping track of batch or lot numbers (on the boxes) when it came to problematic units ... you might check on reddit to see if there are any folks still doing this.

If you lot at the label on the box it has a Lot # and date this will identify the date of manufacturing. Not sure if they will ship the box with the replacement. I replaced 2 and once they send box and second time they didn't.

Thanks. My original device has a lot# 1629. I guess this is the 29th week of 2016. We will see what the replacement is.
