1) Remove ALL power. Remove the AC adapter (Charger) and Battery.
2) FOLLOW Anti-Static Precautions.
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.
Buy, and wear an ESD wrist strap. (Electro Static Discharge)
Connect the alligator clip to a good ground source.
(I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case)
3) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
[If no multi-compartment container is available, you can substitute with a clean egg carton. Label each egg holder ]
SOME screws look VERY similar to other screws.
Advise Do Not mix them up.
4) Make a record as you disassemble. Make notes, and drawings. Use a digital camera, or video camera if available.
Nice to have a Service Manual, but nothing like having your own personal record in case you are interrupted.
5) Service Manual;http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-gateway
Scroll down to the heading Gateway 400. (400 in blue)
Scroll across, and left-click on - EC14
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (EC14) it may take up to 30 seconds, before the first page comes up.
A) ALWAYS make sure all cables are routed back through their channels, when reinstalling them.
They MUST go right back to the same routing they were in, when you opened the laptop.
Otherwise you can pinch a cable, and damage it. (The laptop won't go back together either)
B) Keyboard: One of the toughest things for a person to disconnect, if they have never done it before.
The reasoning is the connector on the motherboard. The Keyboard Cable coming from the laptop, connects to it.
[The Keyboard Cable STAYS attached to the Keyboard. It disconnects from the laptop]
If the connector is Not unlocked correctly, the connector may be broken. Usually means motherboard replacement.
A) There are 4 Latches to depress at the Top of the Keyboard. (LCD screen side is the top)
For the tool I suggest a stiff guitar pick.
Starting from the Left side going towards the Right;
1) In-between the ESC key, and the F1 key (ESC - Escape key)
2) In-between the F5 key and the F6 key.
3) In-between the F10 key and the F11 key.
4) In-between the INS key and the DEL key.
(Insert and Delete keys)
Once you depress a Latch it stays released from it's Retaining Clip.
When all four Latches are depressed, the Keyboard will spring up a little.
EASE the Keyboard forward an inch, or so. (Forward is towards the LCD screen)
The Bottom of the Keyboard has plastic tabs. These tabs stick down into the Palm Rest Cover of the laptop. If you do Not ease the Keyboard forward first, you can break the tabs off.
The Keyboard Cable is still attached to the motherboard also.
Take the top of the Keyboard (Where the Latches are), and roll it up, and over, BUT keep a hold of the Keyboard.
You are turning the Keyboard over with the bottom side up, and Keyboard Cable still attached.
However, you want to only roll the Keyboard down towards the Palm Rest Cover, so far.
This is because the Keyboard Cable is still attached, and it is S-H-O-R-T.
With the Keyboard rolled up a little towards the LCD screen, the Keyboard Cable will unroll enough, so you can get a hold of it.
The Keyboard Cable is a FFC. Flat Flex Cable.
Essentially the cable is several copper wires laid side by side, with a small space in-between each one, and all are coated with a thick plastic.
A type of 'Ribbon Cable'.
However this cable has NO connector attached. There is no insulation on the end of the wires. Metal thin strips are attached to the wire tips,
35 - Conductor Flat Flex Cable,http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg
The Flat Flex Cable inserts down into a type of ZIF connector, on the motherboard. Zero Insertion Force.
The style of ZIF connector used on the motherboard of the EC14, is;
1) A small rectangular block of White plastic, that has a Brown
Locking Bar, going across the top of it.
The Locking Bar flips up. Up to a 90 degree position to Unlock.
The side that you flip up is TOWARDS you.
Use CARE. The tiny hinge pins on the white rectangular block, can break off. The outer hinge area of the brown Locking Tab, on both sides, can break off. (Motherboard replacement)
Make a loose fist with both hands, and use your thumbnails.
I do not suggest using a small metal tool, but if you have to.....
IF you slip, or use too much force with a metal tool, you can not only damage the connector, (May mean motherboard replacement), you can also damage the motherboard.
The Keyboard Cable MUST go back in the same direction, as it was before you removed it.
