The rest of the disassembly process.
The next thing that needs to be done is removing of the palmrest. (This particular model)
The palmrest is released from the rest of the assembly by the removal of 5 screws on the bottom of the laptop. These are indicated here by red arrows:
They are also indicated on the bottom of the laptop by a circle with the letter 'P' inside of it next to the location of each screw.
The electronic components of the palmrest are disconnected from the main circuit by pulling this tab, which contained one of the keyboard connectors on it, straight up away from the main circuit board. Also, if the CMOS information needs to be cleared for any reason, it can be done by disconnecting this connector for only a few seconds. This is because the battery is located in the palmrest just above the right speaker (at least on this model.) And because this particular CMOS chip doesn't hold its data very long without a battery, and is located on the main board. I personally found this to be somewhat odd.
Now the latch pictured here must be released from its hold on the bottom of the case. I used a small flat screwdriver to gently pry it back while easing the front of the palmrest upwards. Be careful not to lift the palmrest up too much, as there are still 2 more hitches securing it to the rest of the case.
There are 2 latches, one on each side of the palmrest. They are towards the back of the palmrest, near the screen. They can be unhooked from the main assembly in the manner shown in this picture, by lifting the corner of the other section of the case up about a millimeter. After both of these are freed the palmrest can be lifted away.
The official repair manual for this laptop stated that the display must be removed before the palmrest can be taken off. But, as you can see, for anyone who is mechanically inclined enough to be able to cross a country road, this is not actually necessary. (Although this procedure does require the removal of the screen, which is next.)
The first thing that needs to be done when removing the screen is to disconnect this ribbon cable from its connector on the motherboard by pulling it upwards. This is the only electronic connection that the screen has with the rest of the notebook.
To release the screen from the main assembly, the 3 screws shown here by red arrows, and also by a circle containing the letter 'D' next to each screw.
Make sure you keep track of all screws, put them in something, and keep track of which ones go where.
The motherboard is the next part to be removed. This model has 2 screws fastening the motherboard to the case as shown in the picture. There are 2 more photos following, which show close-ups of each screw to avoid any confusion. They are shown by red arrows in the photographs. But, unlike previous screws, they do not have a convenient circled letter next to them.
* For this model, these are the only screws that need to be removed on the motherboard! There are other screws which may look as though they need to be removed, such as the ones by the processor or fan but these should not be removed.
Remember to check the next 2 pictures first.
The screw on the left.
Applying a steady gentle lifting force under the middle fore section of the motherboard causes it to swing up.
