A Basic Guide to Identifying the Major Components of a Laptop System.



The following guides will provide a visual guide to each of the major components you will find on any notebook computer currently shipping or having shipped in the last 10 years. They will also give some basic info on each component as well. If this guide doesn't answer your question then please contact your Local Support.


Visual Guides to the Various Notebook Components

Note: Colour and Configuration may change depending on your System Type. This guide is only meant to provide a basic knowledge of what each part is and does in your Computer.

What it Looks like and What it does?

(Fig.1.1 HDD and SSD notebook drives)

The HDD (Hard Disk Drive)/SSD (Solid State Drive) is the part of your Computer which holds your Software and Data.

(Fig.1.2 Removing drive caddy from Notebook)

The HDD in a Notebook is 2.5" wide and is Silver on top, with a circuit board on the base.

The SSD in a Notebook is 2.5" wide, usually Black on top, with a circuit board with chips on the base.

The HDD/SSD has no cables which connect to them. The drives plug straight to a connector on your Motherboard.

There are some System Type's which will use a Ribbon cable to connect the HDD/SSD to the Motherboard, but these are System Types where the HDD/SSD will not be considered to be a Customer Replaceable Part (CRU).

The HDD/SSD will be secured in place, either in a Cage or with Phillips head screws, depending on your System Type.

HDD's are older technology with spinning platters that can store a lot of data. SSD's are newer technology which ups the drives access speeds by using flash memory instead of platters. SSD's are a common upgrade part to improve the speed of most systems, but the storage sizes are still short of what an HDD can handle. Combinations of both are used for fast boot and seek speeds, while still holding space for saved data.

What it looks Like and What it does?

(Fig.2.1 Memory Dimm (Dual Inline Memory Module))

The Memory is the part of your Computer which lets it transfer Data between your Software programs and the more you have the more it speeds up your experience of using the programs.

(Fig.2.2 Memory Retaining Clips)

The Memory in a Notebook is not compatible with that fitted in Desktops. The Memory DIMM is only 2" long and 1" tall, with a Golden fringe along the bottom and there will be a notch cut out of the fringe.

To Release the Memory you pull apart the clips at either side of the Memory and it rises up at a 45 degree angle which is far enough up that you can pull it completely out of the slot.

To Reseat the Memory you push the Memory into the slot and then push straight down, making sure it's the correct way round and the clips either side of the slot will catch the Memory in place. This secures the Memory in place and if the clips do not catch the Memory in place or you can see any of the gold fringe on the bottom of the Memory outside of the slot, then it isn't seated properly.

The Memory card has a notch cut in the bottom which matches a bar in the Memory slot. It will only allow the Memory to be fitted in the Memory slot the correct way round. The position of the notch denotes which type of memory and memory slot you have. This is different on everything from DDR to DDR4.
