How to disassemble a laptop? A series of video tutorials coming from codeandwine is continued by showing how to remove the motherboard of the Dell Inspiron, N4110.
In this video tutorial Koza continues by removing the screws holding the motherboard of the Dell Inspiron N4110 also known as the Dell 14R. Step by step explanations are given then shown. For the written content of what was done in the removal of the motherboard, refer to information below.
Materials Needed
Philips Number 1 Screw Driver
Hard, flat edged tool - preferable NOT a flat screw driver
Plastic Lever - In my case: a make up brush
Paint Brush - If you plan to clean your pieces along the way
Enough table area to set computer parts easily
Area to put screws
Things to do
Remove all the connections from other devices unto the motherboard
Unscrew the screw that is holding the motherboard which comes from the screen
Unscrew the 5 Screws Labeled B1 through B5.
Grab Plastic Lever and insert through the sides of the motherboard where it connects to the I/O circuit board. Gently push up from one side, then from the other, until motherbord is released
Set motherboard vertically towards the screen in order to remove the connection of the power supply
Take out motherboard while holding the case of the computer so that it does not fall backwards. Or set something behind the screen before releasing motherboard, so that it holds the weight of the screen.
Replacing
Acquire your new motherboard
Horizontally, tilt up to connect the power suply once more on to the motherboard
Place motherboard down and insert heat sink side first
Make sure none of the connections coming from the speaker, screen, etc., are left under the motherboard.
Press down gently on the right hand side by the I/O circuit board to allow connecting bars to fall into the holes of the I/O circuit board.
Once settled down, connect all connections coming from speakers, screen, VGA port (after setting cooling fan back)
Screw the screw coming from the screen by the cooling fan.
Screw the five screws labeled B1 through B5 back in place.
Documentation/Annotation of Motherboard
1 Pink
These two connectors enclosed in the pink area, are the ones that connect the motherboard to the USB/LAN and I/O circuit board.
2 Green
The connector shown enclosed in the green area is the one that the battery fits into. This part is essential in keeping laptop on when running on battery, charging battery, and overall on power for the laptop itself.
3 Yellow
The area in yellow shows the ports for the DDR3 memory cards. Using of memory cards or memory in its context, is essential for the
multitasking done in the computer. For example, the analogy often used with memory is that memory is like the top table space of your office
table. You can fill your table with paper, but to see each paper there shouldn't be anything on top of it. So the amount of papers spaced
out nicely on your table is the capacity that your top table has.
Similarly with memory, the amount of memory you have, assuming eachprogram is a different sized paper on your table, is the capacity your
computer has to run several programs at the same time without running radically slow.
Once you have a ton of windows open and you see your laptop slowing down, it is because you are working most of the memory
capacity your laptop brings.
4 Blue
The blue square shown, is the connector for the power supply coming from the power entrance of your laptop. Here is where you insert or
remove the wire for the powe slot of your laptop. The importance of this is to give the laptop power to turn on and do all its task by
acquiring the current being given, coming from when you connect your laptop's charger to the outlet at your house, and delivering this
energy throughout the motherboard different components as needed by each one.
5 Red
The red square shown on the motherboard is the socket where the processor is placed. The processor is the most important piece in your
laptop. This socket allows for the processor to be placed and locked to communicate with your laptop. As the name says it, this particular
piece is in charge of managing processes being sent in and out from the computer. Incoming processes can come from the processes required
for your computer to stay on, or they can come when programs are called and their uses are extensive, such as video designging, editting,
picture edditting, running virtual machines, among many other processes these user called programs ask from your laptop.
6 Peach
The peach square area shown on the motherboard is where the Hard Disk Drive for the Dell Inspiron N4110 goes. This is a SATA port and is
crucial for storage. Although now you can run an operating system through an external USB or other forms, the Hard Disk Drive found on
your laptop is the default place where the Operating System for your laptop would be installed; where files would be saved; and where saved
data can be retrieved from.
7 Purple
The purple area shown on the motherboard of the Dell Inspiron N4110 is the CMOS, short for Complementary Metal-Oxide Semiconductor, battery.
CMOS is usually referred to as a small amount of memory that holds date and time and small little things like those, and are stored in the
BIOS settings of the motherboard. This is usually powered by the CMOS batter which tends to be a small coin cell battery which can last up
to ten years!
8 Orange-brown
The orange brown squared labeled number eight is the HDMI slot of your laptop. This HDMI 1.4 slot is particularly important when you want to
connect your laptop to some other peripheral whose port entrance is an HDMI. This port can also be used in say, connecting your laptop to
a flat screen television to watch a movie off your laptop, on the tv. This port transmits both audio and display from the laptop; thus,
saving the need to connect that headphone jack.
9 White
The white square area shown on the motherboard is the eSATA port. This port is essential when dealing with peripherals that need SATA
entrances to connect with our laptop.
10 Navy Blue
The navy blue square on the motherboard is the USB 2.0 port. This port is very handy to your laptop, as it is where you would plug in
your USB's or flashdrives, and where you can plug in many other peripheral devices that need to communicate to your laptop. Some of those
would probably be your phone to laptop cable charger, your printer, and many more.
11 Brown
The brown area is known as the NorthBridge. The northbridge is particularly always close to your processor, and many times under a heat
sink. The northbridge is like a controller in the motherboard of your laptop, which helps in organizing processes that are coming in and out
of the processor. Usually this would get hot too, so anyone opening or touching the North Bridge should make sure it has cooled down. In
the case of the Dell Inspiron, it is all under the same heatsink as the one holding the processor, with two distinct screws and silver
plate on top of it when compared to the thick, 4 screws cover over the processor itself.
