Opening notebook Toshiba Satellite Pro SP4270

(Updated Aug 12 2012)
(Updated Aug 29 2013)

Introduction

The CPU fan of my old notebook, a 2000 Toshiba Satellite Pro SP4270, stopped working: cpu and motherboard temperatures raised above 70C and 60C, while they usually were about 40-45C and rarely reached 50C.
The most likely cause is dust on the fan, so I decided to open the notebook to make some cleaning.

Steps

Here are the steps to dismount the notebook: I also caught the opportunity to clean the keyboard under the keys, which you can imagine how much dust was hiding after 8 years of use; so I took away every single key, pulling it towards left and then towards right. Removing and cleaning the keys is quite risky, in fact a key has broken in two parts while cleaning it, and another one lost one of the plastic pins that fasten the key to its support. I had to use some glue to repair them, and the one without the pins now is loose; fortunately it's the Fn key, which I seldom use.

New problem: the display becomes dark when it's opened more than 90 degrees. I opened up the notebook (and I added a few more precise steps in the above description) to see if I could identify the cause of this problem: I didn't find anything visibly wrong, so I just removed the metal lock which was keeping the display cable in place and I moved a little bit the cable; this was just enough to solve the problem! I remounted the metal lock and reassembled the notebook, and now the display works like a charm at all inclinations, no more dark screens.

Same problem of Aug 12 2012, the display becomes dark at some positions, with a barely visible shadow, but now it's worse: moving the cable is not enough, and looking attentively at the cable I see it's ruined; with the notebook opened up and switched on I can even see a few little sparks.
I found on ebay an used replacement cable, I ordered and replaced it. It works, I spent less than 20 euros and I can go on using my 13 years old notebook as a wireless rdp terminal.
Here are the steps to replace the screen cable after opening up the Toshiba SP4270:
