Ge Transformer Serial Numbers
Apr 13, 2012 Serial # interpretation This info. Was posted over on XDA regarding interpretation of the serial numbers. Ge transformer serial numbers and date codes. For example, if the serial number begins with the letters 'GA,' the appliance age is April of 2001. Note: Every ten years or so, we run through the alphabet, and start over at letter A. So, some serial numbers may be duplicated, but correspond with different years.

Reading Ge Serial Numbers
This info. was posted over on XDA regarding interpretation of the serial numbers. No idea if it's correct, but apparently this info. is located somewhere on the Asus website. Maybe this will come in handy in the future for finding a trend in reliability vs. serial #
From their website:
ASUS products have serial numbers that are 10 - 15 digits long. They have the following format:
1st digit: Year Manufactured (last digit of the year) (0 may be represented. by 'A')
2nd digit: Month Manufactured (1-9, A-C)
3rd digit: Product code ('N' for notebook, 'M' for motherboard, etc.)
So 'C1' TFPs are manufactured in Jan 2012, and 'BC' ones were mfg'd in Dec 2011.
