#2 Let's Note CF-SX2

I've got junk CF-SX2, intending to take LCD to replace broken LCD for the another SX2.
The photo on Auction site seemed a little bit different, the frame size was a little bit wide. And another intention is to take power related parts to replace another SX2 which the power line is broken.

All the work went fine, except the I broke frame (Junk side) which I did not notice the way to un assemble. I should have LCD and body get flat, and just should have move the body to upper. I did not loose anything by this, because I do not need this parts.

  1. Old one: junk, BIOS password is set and unknown. LCD looks OK
  2. Newer one: Working but LCD was broken
  • The LCD panel is really a little bit small. It is OK, a kind of expected,
  • The connector location is different on LCD side, the newer one cable was too short to reach
  • I've picked the LCD cable from the old one and use it
  • I took hard time to connect the LCD cable to LCD, right/left or flipped or not, but finally resovled by referencing the another set of LCD/cable combination of which LCD is broken.
  • Then .. the RAM mapping is different. four console windows appear
  • And worse, X11 won't work (won't show meaningfull screen)
  • On the way to this swap work, I've replaced the internal RAM from 4GB to 8GB, so now total get 16GB, see below

LCD のこわれた Let's Note CF-SX2 が二台ある。以前に新品の液晶だけ買ったことがあるが、 何とはなく良い思い出がなくて、避けていた。それで NX2 の パスワード付のジャンクがあって、

確かに LCD が少し小さかったが、まあ、許容範囲かなと。ところが、
  • まず、線が短かかった。LCD 側のコネクタの位置が違う。これは万事休す、かなと 思ったが、LCD への線までも交換することで何とかなった
  • 線と LCD の接続は、どちら向きかなかなか理解出来なかったが、以前の割れた LCD があって、それの接続を見て、何とか理解し、うまく差せた
  • それで動作確認をしたが、何と、RAM の mapping が違う console の時は、それでも読めるので、LCD 無よりはよっぽど良いが、実は X Windows 11 は全然絵にならない。いづれ、取替えることとしよう。


ただし、ついでに内蔵の RAM を 8GB に交換したので、全部で 16GB になった
