Laptop Serial Number Format

[John Watlington]

The XO serial numbers are structured as follows

AABYWWSSSSS

AA - Area, where SH is QSMC (Shanghai), and CS is CSMC (Changshu)
B - Factory
Y - Last digit of year of production
WW - ISO week number of production
SSSSS - unique identifier (in hex)

Example:
SHF80801FA0
is a laptop made in Factory 6 at QSMC, in the 8th
week of 2008, with unique ID (for that week) of 01FA0
