fujitsu already moving some of the parts of production to China. There are also certain Fujitsu-Siemens joint venture models which are printed as Made in China.
The Fujitsu N series and the new cheaper models are also Made in China.
Same for Sony N & C series.
Made in Japan just mades that the laptop is assembled in Japan.
Firstly, components like keyboard, LCDs, CPU, Harddisk, RAM, optical drive, adaptor, wireless card, bluetooth card are generic parts which are from 3rd parties. These parts can be made in China, USA, Mexico, Taiwan etc.
The only parts that are fujitsu designed are the Chasis and motherboard only.
These are usually made in China or Taiwan too, definitely not Japan.
For batteries, note that the battery PCB circuitry might be Japan designed, but the battery PCB board is made in China too. the internal batteries cells are not in house by fujitsu definitely. Do a google search, you will find that for the recent recall of Sony laptop battery cells, Fujitsu is one of the companies who recall it back.
Fujitsu does not produce their own laptop battery cells as far as I konw. Correct me if I am wrong. Japanese major battery cells producers are Sony, Panasonic and Sanyo.
We also have Korean cells such as LG.
Fujitsu is just Assembled in Japan, QC in Japan, this is enough for them to put down as Made in Japan, as the final product is finish at Japan. Quality is likely to be better due to the higher QC standards in Japan. That's all. Nothing to shout about.
