Replace keyboard


Yes Bruce, Absolutely!

1) http://www.youtube.com/watch?v=vqQ3kdtUNFc

2) The Keyboard Cable STAYS attached to the Keyboard.
It removes FROM the motherboard connector.

The Keyboard Cable is a FFC. Flat Flex Cable.
General example of a FFC,

http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg

NOTE that there is no connector attached to the cable.
Just exposed flat contact pins.
These contact pins MUST line back up, as when the cable was originally installed.

For this reason I suggest making a mark (Sharpee?), on one side of the cable, and a matching mark on the same side of the motherboard connector; BEFORE removing the Keyboard Cable from the motherboard connector.

Gives you a reference as to which way the new Keyboard Cable goes, when installing the new Keyboard.
Twisted, flipped over,....going to Florida for vacation; the new Keyboard Cable MUST go back same position, as the old Keyboard Cable.

What he is depressing are 3 spring Detent's above the Keyboard.
Approximate locations;
A) Above the F2 and F3 keys
B) Above the F7 and F8 keys
C) Above the Prt Scr and Pause/Break keys.

Small rounded tabs. Along the lines of this Asus K53u laptop example,

http://www.insidemylaptop.com/how-to-disassemble-asus-k53u-laptop/

Look at Step 6 and Step 7 photos.
I use a flat tip Jewelers screwdriver. Be gentle so you do not scratch the plastic.
Start on the Right side, gently depress the Detent, and at the same time use a fingernail to gently lift up on the upper right side of the Keyboard, a little.

Now go to the middle Detent, and finally the Detent on the Left.
Lift the Keyboard on the LCD screen side up, JUST A LITTLE.
Then slide up towards the LCD screen, Just a Little.

There are plastic tabs formed out of the Keyboard on the side facing you. If you bring the Keyboard straight up, you chance breaking those tabs off.
Tabs cleared, roll the top of the Keyboard, (LCD screen side), towards you.
Be gentle as the Keyboard Cable is STILL attached; you can only go so far.

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is composed of two pieces, but does NOT come completely apart.

Three styles are used, two currently to my knowledge.
Yours is the Flip Up type.

The bottom part is rectangular in shape, and is the larger piece.
It is stationary to the motherboard, and is called the BODY.

The top part is also rectangular in shape, and is the smaller of the two parts.
It is movable, and is called the Locking Bar.

IF, the Locking Bar comes off of the Body, it is broken; or the hinge pins in the Body the Locking Tab hinges on; are broken.

This = MOTHERBOARD REPLACEMENT, and why I am being so detailed.
Be G-E-N-T-L-E with this connector.

(You'll be OK, I'm just giving you a 'heads up')

Locked; or can be said as Closed; position,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-13.jpg

Unlocked, or can be said as Open; position,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-14.jpg

About 10 minutes, and you should be clicking keys away!

Just from a quick search. Suggest perform your own, and suggest from a reputable dealer also,

Good afternoon. I disassembled my Asus eeepc 900hd to fix a fan noise; in doing that, the connector of the touch pad went outside its alluminium adesive holder. How can I put it bak in place?


Do you mean on the keyboard side, or the motherboard side? If it was keyboard side, there's nothing that can be done except buy a new keyboard. If it's on the motherboard side, there should be a clamp that can be released by either sliding or lifting slightly. Insert the ribbon cable back into the contact, and close the clamp.

Dear sir/mam I have a sony vaio vgn fj270 laptop,3 days ago small amount of sprite spilled overthe key board and aome of the keys became stuck, a professional cleaned the keyboard unffortunately something...


There is not so much that could be done to repair a keyboard. Disassemble the laptop, check the ribbon cable connecting the keyboard to the motherboard. If the ribbon cable is loose, tighten it. If it is tight, replace the keyboard with a new one

This guide is to provide some help for those who want to disassemble their laptop.
You have to be sure that the problem you face is from the hardware, and that your laptop is not under warranty, since that laptop disassembly void warranty.
Search on the net for service manuals some are free and other cost around 6$ . Not find your model ? download some free service manual from different brands and read them many steps are the same in laptop disassembly. But i do recommended to find the manual that fit your laptop because you may need to know the part number of the defective part to change it.
Now you have to prepare a clean working area with small box for the different parts and their screws, and maybe a pen and a paper to remember particular step.
To disassemble the computer, you need the tools below:
Wrist ground strap and conductive mat for preventing electrostatic discharge
Small Phillips screw driver
Flat head screw driver
Hexagonal driver
Tweezers
NOTE : The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components.
When you remove the stripe cover, please be careful not to scrape the cover.
In most of laptop you can actually access by the base to these bays :
battery
memory
hard disk
Remove them all, to remove the optical disk just release the screw securing the optical disk module,push the ODD module using a screwdriver and remove the ODD module from the main unit.
After that look on the keyboard area to find how to remove the keyboard for example with an Acer aspire 5100, you have to remove the middle cover from the edge of the middle cover and carefully detach the middle cover, then you just have to release the two screws securing the keyboard plate and carefully detach the keyboard plate from the edge of the keyboard plate finish by release the keyboard FFC lock carefully because it is fragile. Then remove the keyboard plate.
After that you can either disassembly the lcd module or try to access the motherboard.
For the LCD module carefully disconnect the LCD cable and any other cable that you can see, release any screws holding the LCD module on the bottom side of the main unit, release any other screws securing the LCD hinges on the main unit, then detach the LCD module from the main unit.
For the motherboard every model are different then you have to explore by yourself, but not forget to read some service manuals before.
You can find some free service manuals at laptop support.
I hope that this will give some help.
Didier Pradel is the webmaster of laptop support where you can find many useful informations, and help for your lovely laptop.

How to dissassembled IBM thinkpad 570


The keyboard is held by two screws on the bottom of the machine, then you just need to work it up ay one side and off. I've had a few that the keyboard was stuck, and had to pull a little harder to get it off. When separating the plastics, there are a few hidden screws under black sticky pads, 4 at the front of the machine that I can think of right off hand, make sure you get these. Once you get the keyboard off, just take your time and be sure to remove all visible screws. Here's a link to some IBM service manuals. Couldn't find one for the 570, but the T series have the same basic design. Look over the manuals, they should be able to give you a better idea of hoe they come apart.
