Workshop 01.0 - Hardware Elite 8100-8300

Today we'll:

  • Identify your computer
  • Learn its components
  • Disassemble/reassemble it quickly

The Computer

See basic information on the label:

  • Manufacturer: Hewlett Packard.
  • Model : 8100 Elite.
  • Form Factor (size): Small Form Factor (SFF) - meaning it's a smaller case (Important for purchasing new hardware).
  • Computer Type: PC - Personal computer.

Safety First

Unplug the power cable before opening the case.

  • Plug/unplug cables holding the connector, not the wire.
  • Be careful with sharp screwdrivers/sharp edges on components.

Take a break if ever frustrated. Help is always available.

Tools

You require patience, bench space, and tools:

  • Screwdrivers
  • Wipes
  • Spray and wipe cleaner
  • Paper towel
  • Thermal paste
  • Vacuum cleaner/Compressed air

Case Exterior

Wipe it down and look at what's outside the case.

Ports/Sockets/Buttons

Standard connection points (ports or sockets) vary so we connect things correctly:

Power

A three-pin power socket on the Power Supply Unit (PSU).

USB

Universal Serial Bus (USB) ports connect to USB devices.

Video

Connect to monitors/TVs with Video Graphics Array (VGA) Ports:

or Display Ports:

Ethernet

An ethernet port uses a network cable for network/internet access.

Audio

Audio sockets connect to audio plugs/jacks:

  • Blue = audio in (microphone, etc)
  • Red = audio out (headphones, speakers, etc)

Legacy Ports

PS/2 ports connect to older keyboards/mice:

Serial ports connect to older industrial devices:

Inside the Case

Place computer flat facing you. Open case with the back latch.

Use the lid as a tray to store parts together.

Discharge Static

Touch a large metal object to discharge any static before touching things, as static 'shock' can damage components.

Clean

Clear dust around the vents/fans from outside with the vacuum/compressed air. Be careful - don't hit components.

Then clean inside:

Wipe the case interior with a cloth.

Components

Let's identify internal components:

Power Supply Unit

Power Supply Unit (PSU): converts electricity from your mains voltage (240 volts), into smaller voltages for your computer.

It can hold dangerous voltages even once switched off/unplugged. Never disassemble!

Motherboard

motherboard: allows components to communicate together.

Hard Drive

Hard drive (hard disk): permanently stores data (eg, your files).

DVD drive

DVD drive: reads/writes Digital Versatile Discs (DVDs).

PCI expansion slots

Install expansion cards to add additional functionality - eg, video cards

Random Access Memory (RAM)

RAM: stores data used to run programs. Data in RAM disappears when your computer turns off.

Central Processing Unit (CPU)/Heatsink

CPU: the 'brain' of your computer. The heatsink regulates its temperature.

CPU fan

CPU fan: directs air over the CPU/heatsink.

Battery

Cables

Power cables: carry power from the PSU to components.

SATA data cables: carry information between components.

Disassembly

Before we disassemble, photograph the components for your reference.

Green tabs/catches help you remove most components without tools.

DVD Drive

Flip the PSU up to make room. The DVD drive's in a movable bay for easy access.

Pull the green tab on the right up - the bay will swing up.

Unplug the power/data cables from the drive.

Unclip the cable guide and free the cables.

Unplug the SATA cable from the motherboard.

Push the DVD drive bay back down, then hold the green button on the left.

Slide the drive forward, and lift straight up to remove from the bay.

The drive label contains information to help replace/upgrade the drive.

Hard Drive

Unplug power and SATA cables from the hard drive.

Push down the green tab on the right of the drive bay. Slide the hard drive forward.

Lift it straight up and out.

Free cables from the cable guide.

Unplug SATA cable from the motherboard.

The drive label contains information to help replace/upgrade the drive.

PSU

Unplug power supply cables on the motherboard.

  • The connectors have squeeze tabs - squeeze them and wiggle gently to release.

The front cable supplies power to the CPU:

Another powers most components:

The one with black connectors connects the motherboard to the drives.

Clear the cables, then tilt the PSU and lift straight out.

The label contains:

  • Input voltage(s)
  • Output voltages
  • Maximum power (in watts)

RAM

The RAM is held in by tabs (or clips) in sockets on the motherboard.

Press tabs hard on either side of the first RAM stick.

Pull it out.

Don't touch the gold parts on RAM, as skin cells/sweat can cause corrosion

Don't touch the memory chips. Static electrical discharge can easily damage or destroy them.

Put RAM down carefully and repeat for the second.

The label contains information to help replace/upgrade your RAM. RAM has a module name (written on the stick) you'll need to match to its standard name (how RAM is sold) to replace/upgrade.

Common RAM types:

Standard name
DDR3-800D PC3-6400 DDR3-1600G* PC3-12800
DDR3-800E DDR3-1600H
DDR3-1066E PC3-8500 DDR3-1600J
DDR3-1066F DDR3-1600K
DDR3-1066G DDR3-1866J* PC3-14900
DDR3-1333F* PC3-10600 DDR3-1866K
DDR3-1333G DDR3-1866L
DDR3-1333H DDR3-1866M*
DDR3-1333J* DDR3-2133K* PC3-17000
DDR3-2133L
DDR3-2133M
DDR3-2133N*

Front Face

Remove the front panel with the power switch button.

Lift the three top tabs:

And remove.

Front Fan

Remove the black plastic air-guide first.

Four tabs on the fan connect it to the chassis. Squeeze in the top two tabs:

Then push the two button tabs. If you have trouble, use a flathead screw driver.

Unplug fan cable from the motherboard header. Clean it if needed.

Motherboard/Heatsink

Unplug the remaining cables connecting to the front panel. They connect to headers on the motherboard (lower left). First the power header:

then front USB header:

front audio header:

speaker header:

and intrusion switch.

Remove the eight screws securing the motherboard. Leave the four screws around the CPU for now.

When removing the heatsink do not touch the sticky paste on the heatsink/CPU. This thermal paste improves heat transfer between these components.

The heatsink is secured under pressure with four screws. Unscrew them:

Lift the heatsink straight up:

Place carefully upside-down to avoid smearing the paste.

Motherboards are only removed at a certain angle. Proceed carefully.

Lift the motherboard from the front, then slide gently forward to free the back sockets.

Lift and twist to clear from the case. Lay in a clear space.

Find labels for:

  • PSU connections
  • Front panel connectors
  • USB and SATA connectors

CPU

The CPU and CPU socket are very delicate. Be extremely careful.

It attaches to the motherboard in a socket. Press down and push the lever to the side. It will pop out.

Lift the gate:

Carefully remove the CPU with two fingers, from the edges with small notches in the socket.

Look at the underside of the CPU - don't touch the gold parts.

Hundreds of pins each connect to a gold circle on the base of the CPU.

Place the CPU upside-down on your heatsink.

Clean CPU/Heatsink

Once exposed to air, heatsink paste dries. Scrape away old heatsink paste and apply new.

Lift the CPU off the heatsink and flip it. Wipe clean with your cloth until you can clearly read the text.

Can you read the:

  • CPU speed
  • Model number
  • Where it was made?

Place the CPU gently back in the socket with notches lined up - it only fits one way!

Clean the heatsink with your cloth - wipe with the grain.
