inside of a typical laptop PC.
00:10
In this demo, we will be examining components in a typical laptop computer.
00:15
Laptops are also referred to as notebooks or portable computers
00:20
and generally offer the same full functionality as a desktop. You see,
00:25
laptops come in many shapes and sizes,
00:28
including regular full size laptops,
00:31
netbooks
00:33
tablets
00:34
and ultrabooks.
00:37
Laptops have several options and characteristics,
00:40
including LCD screens,
00:43
a built in mouse, usually a touch pad
00:46
powered by batteries and typically have external ports for sound USB end video
00:53
on optical drive may also be present
00:56
in this demo. We will see where many of these features are present and delve deeper into the internal components of a laptop.
01:03
In this demo, we will be looking inside the laptop PC shown.
01:07
First, let's look at some of the external features on this laptop
01:12
On the top of the laptop, you can see the LCD monitor,
01:15
the keyboard
01:17
and the touch pad.
01:18
If we look at the left side of the laptop
01:21
and you can see there are USB ports and an optical drive.
01:26
If you look at the right side of the computer, you will see an express card slot, a memory card slot and audio ports, including a headphone jack and a microphone jack.
01:36
Next, looking at the back side of the laptop, there are several important ports and connectors. Note the Ethernet and USB ports.
01:45
There are also connectors for Devi I and V G. A. Video out
01:49
last. There is also a connector for the power input for the external power supply.
01:56
This is one important feature for laptops that differ from a standard PC.
02:00
For these portable devices, the power supply is an external device that plugs into the wall socket and into the computer.
02:08
Now let's look at the bottom of the laptop.
02:13
Looking at the bottom of the laptop. You will notice several features. First,
02:16
let's examine the laptop battery.
02:20
You'll notice the battery release lever located above the battery.
02:23
When depressed, you can remove the battery.
02:27
Next, you will notice on access panel for the system memory. The RAM.
02:32
There is also an access panel for the wireless network interface card or wireless nick.
02:38
There is also access for the internal hard drive for the laptop.
02:44
Last, there is a port for connecting to a laptop docking station.
02:47
Using your docking station will add additional ports to the laptop.
02:53
Often, the docking station is attached to several non portable devices, like printers and scanners and additional monitors.
03:00
The docking port allows for much more convenient access to these components.
03:07
Now let's take a look at removing the battery and accessing some of the panels
03:12
before accessing laptop internal components. It is very important that you remove all power connections to the device,
03:19
so make sure the power plug is removed.
03:22
Next, you should remove the battery.
03:23
It is also a good idea to wear an anti static bracelet
03:29
to remove the battery, depress the lever and then rock the battery out of the compartment.
03:35
I know this may very depending on the laptop.
03:38
When you remove the battery, it will look something like this.
03:43
Next, we will take a look at the laptops Bram
03:46
to get to the ram, removed the screws from the access panel, and you will see the following.
03:52
Here, you can see that there are two memory sticks. Note. The laptop ram is smaller than RAM used in full size PCs.
04:00
The individual memory sticks can be removed by pressing the release tabs on either side,
04:08
followed by rocking the ramp up and carefully pulling the memory stick out.
04:13
Next, let's take a look at the wireless nick
04:16
to access the wireless network interface card or wireless nick. Remove the access panel screws, and you will see something like the following.
04:27
No, the wireless Nick and a cable connected to it.
04:30
The cable is connected to the antenna for the wireless nick for laptops. This is usually located in the laptop lid wrapped around the outer perimeter of the LCD screen.
04:43
When removing the wireless nick or you are planning on removing the lid, you won't need to disconnect this cable.
04:49
The wireless nick can be removed by disconnecting the connections for the antenna, rocking the card up and carefully pulling it out from the slot.
05:00
Next, we will look at how to access the laptop hard drive.
05:04
Accessing the hard drive can vary depending on laptop design. However, the following example is fairly typical
05:12
to access the hard drive, removed the screws and then slide the drive out.
05:17
Once you remove the hard drive, you may notice that it is mounted to a base plate.
05:24
The hard drive can usually be removed simply by removing the mounting screws like shown here.
05:30
Here is the hard drive removed from the base plate.
05:34
Next, we will examine disassembly of the laptop from the top.
05:40
This will give us access to the motherboard and the internals.
05:45
We will begin by removing the keyboard.
05:47
To do this, we first need to remove a piece of trim
05:50
again. Does well, very by design. However, you will likely need to remove some piece of trim to gain access to the keyboard.
06:00
After removing the keyboard mounting screws, you can carefully pull the keyboard up as shown in the following
06:08
Note that the keyboard is attached to the motherboard with a ribbon connector
06:13
wing disconnecting a ribbon connector. Carefully pull up on the tab.
06:17
The LCD screen can also be detached, and the entire laptop lead can be removed
06:24
for removing the laptop lid and the LCD. It is important to check for several important connectors.
06:30
First, note the connection for the LCD display.
06:33
The connector can be removed from the socket by pulling on the tab.
06:39
Next, note the power connection for the LCD again, This can be removed by gently pulling up on the tab to remove the socket connector.
06:48
Remember the cable we disconnected from the wireless nick for this design. Once disconnected, the cable can be pulled through this hole.
06:58
Lastly, several mounting screws holding the laptop lid to the body should be removed
07:03
before the motherboard can beef.
