Tools Featured in this Teardown

Introduction

As part of the Sony giveaway, I would like to contribute with this VAIO teardown. Bear with me as this is my first tutorial. This is a VGN-T12” wide screen laptop with an Intel Pentium Ma. It’s an oldie that still does the job. Well let’s get to the teardown.

This teardown is not a repair guide. To repair your Sony VAIO VGN T140P, use our service manual.

would this run vista or 7

I believe the requirements for Vista / 7 are 2+ GB of RAM (with 4 recommended). It certainly wouldn't run it fast, by any standards.

  • Loosen 2 latches holding the keyboard down with the flat tip screwdriver, one by the F5 key, and the other by the Num Lock key. Move keyboard towards the touch pad and pull up.

  • Remove the ribbon carefully.

  • I added this step separate for the ones that just want to upgrade the RAM.

You forget there a brown flip that hold the keyboard cable, All you had to do was to flip the brown clip to the left upper position...the cable is loose...

What´s with the fuzzy pictures?

I have the same question. In order to make the pictures really useful, they should be in sharp focus, with proper lighting. A picture in sharp focus, even if it is from a slightly longer distance, is far superior to a close up that is out of focus. The use of a flash should be avoided at all costs. Often the flash will often blow out critical parts of the picture.

just a note to some that might find using a very small pair of needle nose pliers with serrated teeth for replacing the tiny pieces of plastic that secures the ribbons in place ... I have a pair, but they are just a bit too big and I need to find a source for some really small serrated tip pliers, so if anyone can direct me to a source, this would be most helpful and appreciated ... thanks, Jim
