This page describes the disassembly of the XO laptop.
+
Before you disassemble your [[Hardware|XO laptop]], there are some things you should know about staying safe around electricity and small parts. In brief:
-
: '''Arianne''': ''Look at all these cautionsShouldn't we add a "'''Warning: this may break your system!'''" label to disassembly instructions?
+
* '''Protect your eyes.''' Watch out for small pieces of plastic or metal. If you have glasses or safety goggles, wear them.
-
: '''Bernie''': ''Everyone should try disassembling their XO - it was designed for this to be easy for any childPlus, it's fun and a good learning experience.  Maybe we should add a "Warranty void if this seal is '''NOT''' broken" label to encourage people to try it.''
+
* Watch out for electric shock.  '''Always unplug''' your XO and '''take out the battery''' before you disassemble.
 +
* '''Be careful.''' Use a clear workspace so you can see what you are doing, and keep small parts in bowls so they don't fall off the tableUse common sense - if you find yourself yanking really hard on a part, it's probably not supposed to come off that way!
 +
* Follow the [[Motherboard Handling Procedures]]
-
== Cautions ==
+
Read the [[Disassembly safety]] section for more information on how to stay safe. The laptop is [[Disassembly design|designed]] to be easy and safe to take apart, but caution is always a good idea.

'''Eye damage.'''  There is a risk of damage to your eyes due to small pieces of metal or plastic releasing due to force stored during manufacturing or structural stress. Solution: protect your eyes.

|style="color:#000"|
-
'''Static discharge.'''  There is a risk of damage to the system if you touch electronic components.  You will not necessarily feel the discharge for it to do damage.  The damage is not necessarily immediate, the system can fail some months later.  The damage can be cumulative.  '''Solution''': ground yourself before working on your laptop.
+
Here's what you'll need to take apart your [[Hardware|XO laptop]]:
-
'''Remove the main battery and the power cable before starting disassembly''' There is low risk of electric shock, since low voltages are used inside the system. However, there is a risk of accidental shorting with tools or screws. There will remain a clock battery on the main circuit board, powering a small number of circuits.
+
* A '''clean, flat surface''' to work on, with adequate light. Choose a workspace where wind will not blow dust inside the XO and where curious animals will not disrupt your work.
 +
* '''[http://en.wikipedia.org/wiki/Henry_F._Phillips Phillips head] #1 screwdriver''' [[Magnetizing your screwdriver]] will make it easier to work with screws.
 +
* A '''clean container''' (or several) to hold screws and other small parts. Bowls and cups work fine.
 +
* ''Optional:'' A small flat blade screwdriver or '''flat piece of wood/plastic''' (coffee stirrer) for gently prying up the display and camera connectors.  ''Do not twist tool, you will damage the cable.  Gently rotate tool upwards instead.''
 +
* ''Optional:'' anti-static mat or anti-static wrist strap. Connect these to an earth ground.
-
'''Be careful with the motherboard'''
+
A [[Repair center kit|longer list]] is available.
-
Avoid dropping metal objects on the motherboard.  The components used are small enough that dropping a screwdriver on the board may knock off vital components.

However, if you do not, touching a grounded portion of the laptop case (e.g. the screen casing or the heatsink on the motherboard) prior to handling the exposed electronics is usually sufficent to prevent any static damage. Things like extremely low humidity, or wearing synthetic fabrics may increase the risk of static discharge.

You should go through the [[Disassembly top]] instructions if you need to access:
 +
* The screen
 +
* The game buttons
 +
* The power button

* The microphone, camera, or speakers

* The motherboard

Note: before re-assembly, the antennae may seem to deviate from alignment when in the stowed positionThis will change once the bumpers are put back on.  The tops of the antennae meet the green bumpers in a way that brings them closer to the case.

Disassembly safety

IMPORTANT! Read This First!

Before you disassemble your XO laptop, there are some things you should know about staying safe around electricity and small parts. In brief:

  • Protect your eyes. Watch out for small pieces of plastic or metal. If you have glasses or safety goggles, wear them.
  • Watch out for electric shock. Always unplug your XO and take out the battery before you disassemble.
  • Be careful. Use a clear workspace so you can see what you are doing, and keep small parts in bowls so they don't fall off the table. Use common sense - if you find yourself yanking really hard on a part, it's probably not supposed to come off that way!
  • Follow the Motherboard Handling Procedures

Read the Disassembly safety section for more information on how to stay safe. The laptop is designed to be easy and safe to take apart, but caution is always a good idea.

Disassembly tools

Here's what you'll need to take apart your XO laptop:

  • A clean, flat surface to work on, with adequate light. Choose a workspace where wind will not blow dust inside the XO and where curious animals will not disrupt your work.
  • Phillips head #1 screwdriver Magnetizing your screwdriver will make it easier to work with screws.
  • A clean container (or several) to hold screws and other small parts. Bowls and cups work fine.
  • Optional: A small flat blade screwdriver or flat piece of wood/plastic (coffee stirrer) for gently prying up the display and camera connectors. Do not twist tool, you will damage the cable. Gently rotate tool upwards instead.
  • Optional: anti-static mat or anti-static wrist strap. Connect these to an earth ground.

A longer list is available.

A guide to screws used in the XO is available.

You should go through the Disassembly top instructions if you need to access:

  • The screen
  • The game buttons
  • The power button
  • The microphone, camera, or speakers
  • The motherboard
  • The wireless card
