Some notebook series models

A8 = All-purpose laptop with 14" wide screen, 2.4 kg. weight
A9 = Large laptop 15" , 3.2 kg. weight
F2 = Large laptop่ 15" , 2.9 kg. weight

Js = Geforce 7700
Je = Radeon X1450
Ja = Radeon X1600
Jp = Radeon X1700

CPU clocks

CPU clock is 16. The number sixteen must be calculated before knowing real CPU clock. To calculate the clock, simply divide that number by 10 and the result is the minimum range of clock frequency, that is 1.6 Ghz. For the maximum range, just put 9 at the end of the minimum range, and you'll get 1.69 as a result.
Total CPU clock available for this model is between 1.6 to 1.69 Ghz.

Optical drive type

DSM = DVD Super Multi
CMC = Combo Drive

Harddisk capacity

The unit of harddisk capacity showed as GB (Gigabytes), so 100 means 100 GB

CPU Type

c = Celeron
d = Core Duo
Td = Core 2 Duo

For the nearly coming CPU - Core 2 Quad, its code should be something like "Tq". And you may made a guess for more future model codes or even those existing model codes in the market.

this code decode is for asus laptop. The basics are same for all kind of laptop may be free things vary as per the laptop brand.
