No exact guides. Using experience, and one video I found.
Three styles are generally used to fasten a Keyboard to a laptop;
1) Screws come from the Bottom of the laptop, up into the Keyboard.
Not always, but most of the time; there is a marking near the screw hole.
KB, or Keyboard, or a Keyboard symbol; and an arrow pointing from it, at the screw hole.
Screws removed there may be Keyboard Cover screws to remove, and remove the Keyboard Cover also.
2) Keyboard Cover. Cover is above the Keyboard, and below the LCD screen.
Once removed, there are generally 2 to 3 screws, to remove at the Top of the Keyboard; or screws come up from the Bottom of the laptop.
3) Detent Latches.
Spring loaded little latches, immediately above the top edge of the Keyboard.
Usually 3 to 5 latches.
Generally start at the Left side, depress the first latch.
Let's say it is the 3 latch design.
One clip to depress, may be above; and in-between the F2 and F3 keys.
The next clip at the top in-between the F7 and F8 keys.
The last clip at the top in-between the F12 and Insert (Etc), keys.
This is the style I think you have. Amount of spring loaded latches,
I do not know. I base it off of this disassembly video,http://www.youtube.com/watch?v=WrMbmV2daAw
I base it on 10:53 through 10:58 in the video.
He's holding the Top Cover (Palm Rest Cover) in his hand, and the Keyboard is still attached.
(Nope. Never removes Keyboard, lol!)
1) Suggest lay a soft Static free cloth, on the table you're working on.
Helps prevent scratching the table, and laptop.
(DO not perform this on a bed, couch, or directly on a carpet floor.
HIGH areas of Static electricity)
2) Remove ALL power. Remove the AC adapter (Charger), and Battery.
Linked for specifically showing the spring latch design.
Go to Steps 5 through 11.
Steps 5 through 8 for the spring latch info;
9 and 10 for the Keyboard Cable removal, from the ZIF motherboard connector.
A) Keyboard Cable STAYS with Keyboard. It disconnects FROM the motherboard connector.
B) The Keyboard Cable is an FFC. Flat Flex Cable.
It has NO plug connector on the cable, for the motherboard connector.
Just a flat cable with flat terminal contact strips on the end,http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg
It MUST go back in the motherboard connector, the SAME way it came out.
For this reason, you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard connector. (Sharpee?)
Then when installing new Keyboard (If this is what you are after), you compare the two; and line the Keyboard Cable up off of the old one.
The bottom rectangular part, that is white in this example; is the BODY.
It is Stationary to the motherboard.
The upper part, that is Black in this example; is the Locking Bar.
When closed, the Locking Bar wedges the Keyboard Cable, in the Body. Can also be stated as when Locked.
I call this style the Flip-Up style. (Pretty technical, huh? lol!)
You may also have this style, the Slide style,
All you can see of the Locking Bar here, are two 'Tabs' on either side of the Keyboard Cable.
The 'Tabs' are eased up with your Thumbnails.
Use a metal tool, and you can slip. Possibly break the motherboard connector, and could stab the motherboard.
It ONLY moves about 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-
Being detailed because IF you BREAK the motherboard connector, you are looking at MOTHERBOARD REPLACEMENT.
Be careful, go slow.
