This is a description of how to disassemble the top portion of an [[Hardware|XO laptop]]. This is part of the [[Disassembly]] section of the [[XO_Troubleshooting_Guide|Troubleshooting Guide]] and [[Repair|Repair Manual]].

== Similar Guides ==
The following guides refer to disassembly of the laptop to reach a particular component:

* [[Antenna_replacement|Disassembling to replace an antenna]], ([[Disassembly_B4_wireless_antenna|B4 preproduction version]])
* [[Disassembly_backlight|Disassembling the display to replace the backlight]]
* [[Disassembly_XO_person|Disassembling to replace the XO icon on the back cover]]

As a precaution, remember to remove the battery.

== Removing the front panel ==

=== Step 1 ===
Open the laptop and flip the screen up. Rotate it a 90 degree angle as shown in the sequence below.
Next, remove the screws from the bottom of the screen - there are two on each side (right/left) of the XO, so make sure to get all four.

<br style="clear:both" />

=== Step 2 ===

Remove the two green panels from the side of the XO. Slide them upwards and lift them off as shown.

<br style="clear:both" />

=== Step 3 ===

Finally, pull off the front panel. It is tabbed, so it can simply be pulled out. Pull the bottom out (where the screws came out), and gently slide the piece downwards and out.

== Removing the screen ==

Note that if the screen and motherboard aren't being changed, it is not necessary to actually disconnect the screen in order to access the motherboard. Follow step 1, then gently move the screen to perform the following steps (removing the back cover).

=== Step 1 ===

To get the screen out, remove the four screws highlighted.

=== Step 2 ===

Next, carefully slide the screen out, pulling the bottom out. '''Do not''' tug it or let go, as it will still be connected to the motherboard by two cables.

[[image:Screen_4b.jpg|thumb|left|Slide out gently]] [[image:Screen_4c.jpg|thumb|left]][[image:Screen_4d.jpg|thumb|left| Watch out for cables!]]
<br style="clear:both" />
If you are just accessing the motherboard, not changing it or the display, do not unplug the display cables. Simply move the display to access the back cover screws behind it. With every cycle, there is a chance of damage to the display cable connectors on the motherboard.

The connectors have a black plastic bar holding the cable down. To unclamp the cable you have to lift that bar by tugging on the little tab away from the circuit board.

<br style="clear:both" />

== Removing the back cover / reaching the motherboard ==

=== Step 1 ===
[[image:antenna1a.JPG|thumb|left|Take out 4 screws]] [[image:antenna1b.JPG|thumb|left|Turn over. Pull up and remove the back plate]]

<br style="clear:both" />

== Replacing the screen ==

=== Step 1 ===

Reattach the screen by sliding the connection cables into place and clipping them back down (it is generally easier to clip the thinner one that has a longer tether first). Reseat the screen, making sure that it sits flat and that none of the spacers are gone.

<br style="clear:both" />

== Replacing the front panel ==

=== Step 1 ===

Slide the front panel back on, making sure that it sits flat. Note that there are hooks on the side of the panel (highlighted in blue) that need to slide into place; pushing the top of the screen flat and sliding it upwards works well.

[[image:Screen_6a.jpg|thumb|left| Watch out for these hooks]] [[image:Screen_6b.jpg|thumb|left| The rest of the panel slides into place]]
<br style="clear:both" />

=== Step 2 ===

Slide the green side pieces back into place. Then, rotate the XO 90 degrees and put the remaining screws back. Don't forget that the screws go in on both sides (right/left).

Watch out for cables!


If you are just accessing the motherboard, not changing it or the display, do not unplug the display cables. Simply move the display to access the back cover screws behind it. With every cycle, there is a chance of damage to the display cable connectors on the motherboard.

The connectors have a black plastic bar holding the cable down. To unclamp the cable you have to lift that bar by tugging on the little tab away from the circuit board.

Unhook the cable
Watch out for this little cable, too.
Good to go!


Removing the back cover / reaching the motherboard

Step 1

Take out 4 screws
Turn over. Pull up and remove the back plate


Replacing the back cover

Step 1

Turn over. Replace the back plate.
Pick the right screw!
Turn over. Secure the back plate by putting in the four screws where indicated.


Replacing the screen

Step 1

Reattach the screen by sliding the connection cables into place and clipping them back down (it is generally easier to clip the thinner one that has a longer tether first). Reseat the screen, making sure that it sits flat and that none of the spacers are gone.
