-====== Workshop 01.1 - Hardware HP-Elitedesk 800  ====== 
- 
- 
-===== ===== 
- 
-This workshop is an introduction to the hardware practice of The Siganto Digital Learning Workshops (SDLW). In the next three hours you will: 
- 
-  * //Identify your computer// 
-  * //Learn the external ports,sockets and buttons// 
-  * //Know the internal components// 
-  * //Take apart and re-assemble your computer// 
- 
- 
-===== ===== 
- 
-If you are scared of breaking your new computer, don't worry, the SDLW program is all about overcoming that fear. We'll just keep plugging cables, pulling and replacing components over and over to build your practical skills. 
- ==== ==== 
-By the end of this workshop you’ll have the skills to strip your computer bare in less than 15 minutes.  
- ==== ==== 
-And if you break something beyond our capability to fix it, every workshop has a few extra computers which we can use for spare parts. 
- 
- 
- 
- 
- ===== What Kind of Computer is this anyway? ===== 
- 
- ==== ==== 
-Breaking down the name and the labels on your computer is the first step to finding the basic information about your computer. 
- ==== ==== 
- 
-Let's look for details on the outside of your case, try to find  the label that says;  
- 
-  * The **manufacturer** - Hewlett Packard. <WRAP hideslide>An enormous global technology company, HP supplies these computers to large organisations hundreds at a time.</WRAP> 
-  * The **basic model ** - EliteDesk 800. <WRAP hideslide>The model usually has a number and a name. When the number changes it's usually because the model is //upgraded// with newer or better parts</WRAP> 
-  * The **Form Factor** or size = // Small Form Factor (SFF)// .<WRAP hideslide> SFF means the tower or 'base unit' case has a Small Form Factor. It is smaller than the average desktop PC to maximise space in offices. This is important information, as it means any hardware you may like to add to your computer at a later date has to fit in the case!</WRAP> 
-  * And the **type** of computer - PC - [[http://simple.wikipedia.org/wiki/Personal_computer|Personal computer]], intended for one person to use at a time. 
- 
- ==== ==== 
- 
-Is there any other information you can find? 
- 
-  * What do the labels on the side of your computer mean?  
-  * Can you find the operating system that used to be on the computer?

- 
-===== Safety First ===== 
- 
- ==== ==== 
- 
-These are the  main safety issues that have to be identified before we start.  
- 
-<WRAP center round alert 700px> 
- 
-Always unplug the power cable before opening the case!

- 
-</WRAP> 
- ==== ==== 
- 
-Some more general tips; 
- 
-<WRAP center round alert 700px> 
- 
- 
-    * When unplugging or plugging cables, try to grab the connector, not the wire. 
- 
-    * Screwdrivers are sharp! Try to be as gentle as possible when using them. 
- 
-    * The case and components have sharp edges, take care when adding or removing components. 
- 
-</WRAP> 
- 
- 
- ==== ====  
- 
-Finally - if you are getting frustrated, down tools and have a break or a chat, there is no rush and help is always available. 
- 
- 
- 
- 
- ===== Tools ===== 
- 
-<wrap lo>Taking a computer apart requires just a few tools, enough bench space to lay out all the components and a little patience. You'll be provided with the right tools for your workshops.

- 
-===== Outside the Box ===== 
- 
- ==== ====  
-First, we'll be dealing with just the main body of your computer. Your computer could have had a hard life, being kicked around under an office desk or used as a public access computer, so we'll give it good clean.

-<WRAP hideslide>{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:020_case_wipe_1920.jpg?nolink&600 |}}</WRAP> 
- 
-<WRAP hideslide>Grab the big black box and put it on your work table. While you are cleaning the computer, lets find out what we can from the outside of the case.</WRAP> 
- 
- ====  Ports, Sockets and Buttons ==== 
- 
-All desktop computers have a few standard connection points called //ports// or //sockets// on the front and back of the tower case. Ports vary in shape, size and colour to ensure we don't plug in cables incorrectly. We'll go through the ports on your HP8100 one by one. 
- 
- ==== Power ==== 
- 
-There is always a three-pin power socket on the Power Supply Unit (PSU). 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hp800_back_panel_power.jpg?nolink&600 |}} 
- 
- ==== USB ==== 
- 
-One or more [[https://simple.wikipedia.org/wiki/Universal_Serial_Bus|Universal Serial Bus]] (USB) ports, for USB devices. 
- 
-<WRAP center round help 700px> 
-Can you name three things that connect over USB? 
-</WRAP> 
- 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hp800_back_panel_usbs.jpg?nolink&600 |}} 
- 
- ==== Video ====

- 
- ==== Ethernet ==== 
- 
-An [[https://simple.wikipedia.org/wiki/Ethernet|ethernet port]] for connecting to a network cable, used to connect to a network and access the internet. 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hp800_back_panel_ethernet.jpg?nolink&600 |}} 
- 
- ==== Audio ==== 
- 
-Audio sockets, which accept audio connectors, also know as plugs or jacks.<WRAP hideslide> This is how you get audio (sound) in and out of your computer. Blue is for audio in, for a microphone or output from an another device, and red is for audio out, for listening with headphones or speakers.</WRAP> 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hp800_back_panel_audioports.jpg?nolink&600 |}} 
- 
- ==== Legacy Ports ==== 
- 
-Legacy ports, which are not so commonly used on modern computers include 
- 
-PS/2 ports - for older keyboard and mouse connectors 
- 
-Serial ports - commonly for connecting older industrial devices 
-

- 
- ===== Inside the Box ===== 
- 
- ==== ==== 
-It's time to get started! 
- 
-With your computer flat on the desktop and facing you, open the case using the latch at the back. 
- 
-Keep your case lid close by. We will use it to store all the parts and keep them in one place. 
- 
-<WRAP hideslide>{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:019_case_open_1920.jpg?nolink&600 |}}</WRAP> 
- 
- 
- ==== Static ==== 
- 
-Before you touch anything inside your computer discharge any static electrical charge you might have on your body, <WRAP hideslide> as static 'shock' can damage electronic components. This is as simple as touching a large metal object - like your computer case, before touching any components. Now you can get inside your computer with the vacuum, being careful not to hit any components.</WRAP>   
- 
-==== Cleaning  ==== 
- 
-Check out the general level of dust and gunk inside your computer. Look around the vents and fans. <WRAP hideslide>If you see clumps of dust, grab the vacuum or a compressed air can and give it a going over from the outside.</WRAP> 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:022_front_vent_vacuum_1920.jpg?nolink&600 |}}

- 
- 
- ===== Components ===== 
-  
-<WRAP hideslide>Once you've got a nice clean computer, have a look around the inside of it and see if you can identify anything. Don't worry if it's all unfamiliar.</WRAP> By the end of the workshop you'll be able to name and describe all these parts. Here is a quick overview to get us started. 
- 
-<WRAP hideslide>{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_inside.jpg?nolink&600 |}}</WRAP> 
- 
- ==== Power Supply Unit  ====  
- 
-The Power Supply Unit (PSU) converts the electricity from your wall sockets, called the [[https://simple.wikipedia.org/wiki/Volt#Common_voltages|mains]] voltage (240 volts), into the smaller voltages used by your computer.   
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_inside_psu.jpg?nolink&600 |}}

- 
- ==== Motherboard ====  
- 
-The big green board, also called a [[https://simple.wikipedia.org/wiki/Motherboard|mainboard]] is the central part of your computer. All the other parts are connected to it in some way. It is mostly covered by other parts. 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_inside_motherboard.jpg?nolink&600 |}} 
- 
- ==== Hard Drive ====  
- 
-The hard drive - also called a [[https://simple.wikipedia.org/wiki/Hard_disk|hard disk]] is a permanent store of information or //data//. This is where we will install the Operating System later, and where you will store your files like music, movies or documents. The amount of information stored, or //capacity// is measured in gigabytes. 
-   
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_inside_hd.jpg?nolink&600 |}} 
- 
- 
- ==== DVD drive ====  
- 
-The DVD drive reads and writes [[https://simple.wikipedia.org/wiki/DVD|Digital Versatile Discs]]. A DVD drive spins the optical disc at between 500 and 2000 revolutions per minute (RPM). DVD disks are another storage //media// and can store video, audio or other digital data.

- 
- ==== Random Access Memory (RAM) ====  
- 
-[[https://simple.wikipedia.org/wiki/Video_card|RAM]] is where your computer stores data it uses to run programs. Unlike your hard drive, the data in RAM is gone when you turn off your computer. 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_inside_ram.jpg?nolink&600 |}} 
- 
- ==== Central Processing Unit (CPU), heatsink and Fan ====  
- 
-The CPU is the 'brain' of your computer. It contains hundreds of millions of transistors that generate heat. In this model the fan is attached

- 
- ===== What IS a computer? ===== 
- 
-Now that you've seen each part separately, lets talk about what each part does. Here is one way ((https://ubuntuforums.org/showthread.php?t=1491775)) to think about it, using a restaurant as an analogy; 
- 
-==== ==== 
- 
-//A computer is like a kitchen at a restaurant. The computer's processor is like a chef, who works to prepare the food. The faster the chef, the faster food is ready. A dual-core processor is like having a kitchen with two chefs, so two things can be prepared at the same time.// 
- 
- ==== ==== 
-//The computer's RAM is like bench space. Everything in RAM is easy for the processor to get at. If you have a lot of bench space, the chef can work on preparing more things at once. If you don't have enough bench space, the chef can't work on as many things. Some software uses a lot of RAM, just like some recipes call for a lot of ingredients.// 
- ==== ==== 
-//The computer's hard drive is like the cupboards and refrigerator. These spaces hold the ingredients until the chef needs them. If space runs out, then the old ingredients need to be thrown out to make room for new ones.// 
- ==== === 
-//You, the computer user, are then the customer who is ordering things from the kitchen. If the chef is slow, or there isn't enough bench space, it's going to take longer for things to get done, especially if you are ordering a lot of things at once.// 
-  
- ====== Taking it apart ====== 
- 
- ==== ==== 
- 
-Before we start removing parts it's a good time to take a photo of your computer with your phone, so you can refer to it later. 
- 
- ==== ==== 
- 
-Notice the green tabs and catches all through your computer? These are designed to make it possible to pull apart most of your computer without any tools.  
- 
- <WRAP hide>{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:026_psu_flip_up_1920.jpg?nolink&600 |}}</WRAP> 
- 
-===== Remove the DVD Drive ===== 
- 
- ====   ==== 
- 
-Lift up the housing unit that holds the DVD drive and Hard Drive. The DVD drive is installed in a movable bay for easy access. 
- 
- ====   ==== 
- 
-Unplug the power and data cables from the DVD drive. 
- 
-{{ :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:hpelitedesk800_removedvd1.jpg?nolink&600 |}} 
- 
- ====   ==== 
- 
-Push the housing unit back down once you have removed the cables from the back of the DVD drive. Use the green tab at the back of the DVD drive to release it from the housing.

- 
- ====  ====  
- 
-The hard drive label will tell you: 
- 
-  * The capacity in gigabytes 
-  * The form factor (the physical size measured in inches) 
-  * The speed at which it spins 
-  * The manufacturer 
- 
- 
- <WRAP hide>{{background> :engagement:siganto_digital_learning_workshops:workshops:siganto_digital_learning_workshops:041_psu_cpu_mboard_unplug_1920.jpg?nolink&600 |}}</WRAP> 
- 
- ===== Remove the PSU ===== 
- 
-Now we will unplug all the power supply cables on the motherboard.   
-  * The connectors on these cables have small squeeze tabs to release them.

- 
- 
- 
- 
- 
- 
- 
- ====  ====  
- 
-Once again, take a look at the PSU label. Try to find:  
- 
-  * The input voltage(s) 
-  * The output voltages 
-  * The maximum power (in watts) 
- 
- 
-===== Remove the RAM ==== 
- 
-The RAM is held in by tabs (or clips) in sockets on the motherboard.

- ===== Remove the Heatsink ===== 
- 
-This is a tricky job. When we take off the heatsink it is important not to touch the sticky paste on the heatsink or on the top of the CPU. This paste is called thermal paste or thermal transfer compound. 
- 
- ==== ==== 
- 
-The CPU heatsink is directly connected to the CPU, held in place under pressure by four screws. Unscrew the four screws.

- =====  Remove the CPU ====== 
- 
-The CPU and CPU socket are the most delicate parts of your computer. Be extremely careful with this step. 
- 
-==== ==== 
- 
-The CPU attaches to the motherboard in a socket held in place with a gate. Press down and then push the lever on the gate to the side. It will pop out.

-Well done! You are exactly halfway there! Time for a break and don't forget to wash your hands.. 
- 
-===== Part Two: Putting it back together ===== 
- 
- 
- ====== Re-Assembly ===== 
-  
-To re-assemble your computer you need to follow almost the exact same steps in reverse. You should expect it to take at least the same amount of time to put your PC back together. Take it slowly and remember to refer to your snapshot or the image in step 01 of the first session if you can't get a part to fit.

-===== Clean the CPU and heat sink ===== 
- 
-Once the heatsink paste is exposed to air it will dry quickly. We need to scrape the old heat sink paste off and apply new paste. 
- 
- ==== ==== 
- 
-Grab a clean cloth, lift the CPU off the heatsink and flip it over. Wipe the CPU until you can clearly read the text stamped on the CPU itself.

- 
- What can you read on the CPU itself? Can you find the: 
-  * CPU speed 
-  * Model number 
-  * Where it was made? 
- ==== ===  
- 
-Check where the notches are on the sides of the CPU, then place the CPU gently back in the socket with notches lined up for safe keeping. It will only fit one way!
