XO 1.5 USB Keyboard
This page describes how to change the keyboard in a XO-1.5 Laptop to a non-membrane USB version.
Scope
These are detailed instructions for installing a non-membrane keyboard into an XO-1.5 laptop. They apply to all pre-production as well as production models. With little change, they also apply to the later model of the XO-1 (with a single capacitive touchpad).
Credit is freely given to the author of the instructions for doing this modification to an XO-1 (part I, II), found on instructables.com.
WARNING
This modification includes permanent modifications of the XO laptop, and cannot be reversed. Even if you are experienced, there is a significant chance of damaging the laptop beyond repair while following these instructions.
Material
You will need:
- An XO-1 (CL1A) or XO-1.5 (CL1B) laptop
- A micro USB keyboard (such as this one).
- A #1 screwdriver
- Fine pitch soldering equipment
- A magnifier of some sort (lens, loupe, microscope...)
- An X-Acto knife
- A small file and/or fine grade sandpaper
- A way of cutting steel and grinding plastic (such as a Dremel tool)
- cellulose (scotch) or polymide (kapton, preferred) tape
- quick drying epoxy glue or archival double-sided tape
Instructions
Preparing the Keyboard
Dismantling the XO
Modifying the Keyboard Tray
Remove any cable glue residue from the bottom of the keyboard.
Remove the keyboard membrane and two circuit layers.
Cut the keyboard plate as indicated.
Please grind down the edges of the cut metal to avoid personal injury. It is necessary along the edge of the keyboard tray to avoid damaging the keyboard FPC. Bend the top tab of the keyboard tray. Color the sides of the keyboard tray for vanity's sake (w. marker or paint).
