How to change a Vaio TZ keyboard?

Does anybody know how to dismantle the keyboard from a Vaio TZ and assamble another keyboard? Coz I bought a German keyboard and don't want to destroy anything!
Thanks!

any news on this ?
I've the same issue ...

 

I've done it. Wasn't too hard to figure out just by looking.
Don't really have time to take pix and post them right now, and verbal descriptions won't really cut it, but...

First remove all the black screws from the bottom.
Only the black ones. This requires:
* Two different sizes of tiny phillips screwdriver. #0 and #1.
* Remove 3 plastic plugs/caps from the front underside edge. A clean way is to insert a knife as far as it will go into the edge closest to the rear of the unit. Which is also the "tall" or high side of the slanted plugs if looking at the bottom of the unit. Knife should insert about 1/8 inch and hit an obstruction in there that you can't see yet. Pull the knife handle back towards the rear of the unit. Buried tip of knife pries toward the front of the unit. Plastic plug snaps out without damaging either the plug or the case, and the plug snaps back in clean later.
* Remove one of the 2 square rubber feet at the rear. The one that does not have 2 screws within a 1 inch radius. (I'm not near my TZ right now and can't look to say power button side vs power jack side) I think it's the power button side.
* Remove the ram cover to expose another screw in there.
* Remove 1 (out of 3 present) chrome screw inside the battery cavity. It's the one in the middle, not either of the ones that are on the hinges on th left & right ends.
* Leave all the chrome screws alone that are visible through holes in the bottom surface.

Lift the top surface up. You have to stress the hinge parts towards the center a little to pop them out of the hinge caps. Only a little, a millimeter or two. Do one side at a time. You can place a smal flat head screwdriver into a little slot that is there which is normally covered up by the battery and not risk making any marks or gouges that will b visible after re-assembly.
Lift the rear side up and keep the palm rest side close to the bottom half of the unit, and flip over. There is a ribbon cable connected near the mouse pad.

Disconnect the ribbon cable from the motherboard by first lifting up the little plastic retainer clip part of the connecter. Place fingernail against ribbon cable, slide toward connector, lift finger away from ribbon cable. A tiny, thin piece of plastic should flip up, releasing clamp-hold on the ribbon. (Some of the connectors work a different way, sometimes the way to release the clamp is to place fingernail onto the connector, and slide part of the connector towards the ribbon cable. No flipping up. I forget which type every single connector is.)

Now comes a part that really needs a picture, or sufficient mechanical savvy on your part to take this general pointer and get use out of it on your own.

There are several screws on the back of the keyboard + palm rest assembly.
Only 2 or 3 of these needs to be removed to detach the keyboard from the palm rest. If looking at the back of the keyboard with the ribbon cable away frm you, then one of the screws to remove is to the far right, I think it's the farthest-right screw so thats easy. It's holding down an obvious little 1cm square tab. Another is to the left, near the edge close to you, along the same line as the far-right screw. I think no others out in the middle areas need to come off.

Locate the keyboard ribbon cable among the several ribbon cables on the palm rest assembly. The keyboard cable is the one with larger, regularly spaced and sized, black carbon conductors, and the cable has a rounded 90 degree bend. The connector clamp is definitely the flip-up type for that one. I know that one for sure. (I was doing this only last night) Release the clamp for the keyboard cable by flipping it up with a fingernail.and pull the cable out so it lays on top of the connector.

Notice there are several little tab-slides-into-pocket thingies scattered around the back surface. The keyboard has the male tab parts and the palm-rest has the female socket parts, and the keyboard slides out in the obvious way. Don't try to slide the keyboard out yet.

There are 2 (maybe 3, I think just 2 though) places along the edge between the keys and the palm-rest area where you must use a knife point or small flat-head screwdriver to put pressure on some one-way snap formations in the plastic parts. I really can't verbalize exactly how to recognize them or how to release them, but knowing where to look and what to look for in general, should hopefully get you close enough to figure it out instead of breaking the plastic parts, just by virtue of knowing that something is there, and knowing not to worry that there may be other such snaps elsewhere.

When you locate those snap parts, release them and slide the keyboard away from the front edge, only far enough to disengage the little tab/sockets all over. Then start rotating the keyboard while keeping it flat with the palm-rest part, in such a way as to allow the 1/4 circle shaped keyboard ribbon cable to back out of the slot it's threaded into without damaging the cable.

My tz is disassembled at the moment so maybe I'll be able to post some pics later, which would make this far clearer.

It's also possible some of the screws necessary to remove are normally covered by the several large stickers on the bottom of the unit. I removed all the stickers from my unit when I first got it because I hated how ugly they were. I don't remember exactly what was covered originally. I guess I can simply take a pic of my unit and highlight every screw that needs to come off, and that would remove all doubt. Regardless of color or placement or obscuring items like stickers, plugs, and feet, or the existence of other screws that should be left alone.

 

thanks for this
if you can take some pictures it will be perfect !!!
the second part is really hard and I'd stop here the first time ...
I'll probably do an other try this week-end !
