Disassembly of B1 or B2 systems. Warning: this may break your system. The procedure is needed only rarely, such as for hardware debugging by experienced people, such as installation of diagnostic serial ports, or replacement of antennae. |

Before you disassemble your [[Hardware|XO laptop]], there are some things you should know about staying safe around electricity and small parts. In brief: |
|||
== Cautions == |
|||
''' |
* '''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 [[Disassembly design|designed]] to be easy and safe to take apart, but caution is always a good idea. |
|||
'''Anti-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. |

|||
'''Remove power.''' There is low risk of electric shock, since low voltages are used inside the system. There is a risk of accidental shorting with tools or screws. It is best to remove the main battery and the power cable. There will remain a clock battery on the main circuit board. Avoid dropping metal objects. |
|||

|||
|style="color:#000"| |
|||
Here's what you'll need to take apart your [[Hardware|XO laptop]]: |
|||
== Tools == |
|||
* 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. |
|||
*anti-static mat, |
|||
* '''[http://en.wikipedia.org/wiki/Henry_F._Phillips Phillips head] #1 screwdriver''' [[Magnetizing your screwdriver]] will make it easier to work with screws. |
|||
*anti-static wrist strap, |
|||
* A '''clean container''' (or several) to hold screws and other small parts. Bowls and cups work fine. |
|||
*philips head #0 screwdriver, |
|||
* ''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 [[Repair center kit|longer list]] is available. |
|||
== Procedure == |
|||
A [[Screws|guide to screws used in the XO]] is available. |

=== Antennae === |

Disassemble '''XO-1.5''' instructions:<br> |
|||
*pull the antenna connector off the radio module, (in the absence of a proper extraction tool, a pair of pliers held lightly will do, but take care not to crush the connector), |

|||
*remove the hinge structure and affix it to the replacement antenna, with identical orientation, |
|||
|} |
|||
*thread the cable in through the access hole, |
|||
<!-- -------End of second box row----- --> |
|||
*screw down the hinge structure, |
|||
*push the antenna connector onto the radio module socket, (something with a flat end is useful here, the idea is to get the insertion force vertical, and leave no accidental sideways force ... it is very easy for the connector to role sideways). |
|||
Note: before re-assembly, the antennae may seem to deviate from alignment when in the stowed position. This 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. |
