This is the portion of the XO Troubleshooting Guide for diagnosing problems with the keyboard and touchpad of an XO laptop.

Esta es la parte de la Guía diagnóstico del laptop XO para diagnosticar problemas con el teclado y el touchpad de un laptop XO.

¿El teclado parece que no funcione?

When some keys are pressed on the keyboard, the laptop doesn't see them. Or the keyboard may appear completely non-functional, sometimes alternating with periods of correct operation.

Cuando algunas teclas se presionan en el teclado, el laptop no verlos. O el teclado puede parecer totalmente sin funcione, a veces alterna con períodos de funcionamiento correcto.

El touchpad no funciona bien

If both the touchpad and keyboard don't work, then it is likely to be the connection between the keyboard controller and the motherboard (rare), or the keyboard controller. It might be the motherboard, although this has yet to be seen.

Disassemble both the top and the bottom of the laptop. Check the cabling between the motherboard (CN23) and the keyboard controller using an ohmmeter. Unlike the battery cable, there are no hidden connectors in this cable.

If the cable is fine, replace the keyboard controller with a known good one.

If the problem persists, replace the motherboard.

Suspect components on the motherboard include L37 (ferrite supplying 3.3V to the keyboard controller) and the anti-static protection chip U66.

Si ambos el touchpad y el teclado no funciona, es probable que sea la conexión entre el controlador de teclado y la placa madre (raras), o el controlador de teclado. Puede ser la placa base, aunque esto aún no se ha visto.

Desmontar la parte superior y la parte inferior del laptop. Compruebe el cableado entre la placa madre (CN23) y el controlador de teclado usando un ohmiómetro. A diferencia del cable de batería, no hay conectores ocultos en este cable.

Si el cable está bien, sustituir el teclado controlador con un conocido buena.

Si el problema persiste, reemplace la placa base.

Componentes sospechosos en la placa madre incluyen L37 (ferrita en la linea de 3.3V para el controlador de teclado) y el chip de protección anti-estática U66.

¿Tiene usted una tecla modificadora atascado?

If the touchpad works, the keyboard problems may be due to a stuck modifier key ('CTRL', or 'ALT') in the keyboard.

To test for a stuck 'CTRL' or 'ALT' key, open the Terminal activity. Press the 'F' key. If you have a stuck 'ALT' key, pressing the 'F' key will bring up the frame (and make it go away). Alternatively, pressing the 'N' key will bring up the Journal. If nothing happens, press the 'L' key. If you have a stuck 'CTRL' key, pressing 'L' will clear the screen (in the Terminal activity). You can use the keyboard portion of the self-test to verify that the keyboard has stuck keys. Stuck keys are frequently intermittent (they will work fine for a while, then fail.)

If the keyboard has stuck keys, the solution is to replace the keyboard. This was a manufacturing problem (Trac ticket #5658) and has been fixed in newer laptops.

Si el touchpad funciona, el problemas del teclado puede deberse a una tecla modificadora ('CTRL', o 'ALT') pegada en el teclado.

Para comprobar si una pegada 'CTRL' o 'Alt' llave, abrir la actividad Terminal. Pulse la tecla 'F'. Si tiene una pegada clave 'ALT', al pulsar la clave 'F' el Marco se parece (y desaparece). Por otra parte, al pulsar la clave 'N' se abre el Diario. Si no ocurre nada, pulse la 'L' clave. Si tiene una clave 'CTRL' pegado, pulsando 'L' borra la pantalla (en la actividad Terminal). Puede utilizar el parte teclado del Autotest para comprobar si el teclado tiene teclas pegadas. Claves atascado son con frecuencia intermitente (que no tendrán ningún problema por un tiempo, luego faltan.)

Si el teclado tiene teclas pegadas, la solución consiste en sustituir el teclado. Se trataba de un problema de fabricación (billete Trac #5658) y ha sido fijo en los nuevos laptops.

Comprobación del cable de teclado

If the keyboard doesn't appear to have stuck keys, you should check the connector (CN23 on the motherboard).

Disassemble both the top and the bottom of the laptop. Check the cabling between the motherboard (CN23) and the keyboard controller using an ohmmeter. Unlike the battery cable, there are no hidden connectors in this cable.

If the cable appears fine, replace the keyboard controller with a known good one.

If the problem persists, replace the motherboard.

Suspect components on the motherboard include L3 and L5 (ferrites), R94 and R95 (10K), and the anti-static protection chip U66.

Si el teclado no parece tener las llaves pegadas, usted debe comprobar que el conector (CN23 de la placa base).

Desmontar la parte superior y la parte inferior del laptop. Compruebe el cable entre la placa madre (CN23) y el controlador de teclado usando un ohmiómetro. A diferencia del cable de batería, no hay conectores ocultos en este cable.

Si el cable parece muy bien, sustituir el teclado controlador con un conocido buena.

Si el problema persiste, reemplace la placa madre.

Componentes sospechosos en la placa madre incluyen L3 y L5 (ferrites), R94 y R95 (10K), y el anti-estática protección chip U66.

¿El teclado generar respuestas inesperadas?

In this case, the keyboard generates key presses that the user didn't press. For example, a user may press the 'x' key and the laptop thinks that the 'x' key was pressed, followed by the 'c' key. Or a specific key may appear to be pressed intermittently, even when nothing is touching the keyboard.

It is possible that the problem is a loose cable between the keyboard and the keyboard controller. Disassemble the laptop and reseat the cable.

If this doesn't fix the problem, it is probably a "sticky key" on the keyboard, requiring a keyboard replacement.

Están destrozando teclas del teclado

Early production models have a keyboard which allows keys to be easily torn off (Trac ticket #1528). This has been improved in current production laptops.

¿El control no responde?

This is possibly caused by loose cables between the touchpad and the keyboard controller.

If the keyboard is also non-functional, see above section on "keyboard and touchpad both broken".

It could also be the keyboard controller.

¿El control sólo permite movimiento vertical (horizontal)?

There was a fabrication problem which resulted in occasional laptop having a touchpad which only worked in a single direction (Trac ticket #5575). This has been fixed, but the same problem may still be seen occasionally.

The solution to this touchpad problem requires replacing the actual touchpad surface. Replacing just the touchpad surface is not recommended, as it is strongly glued down. Replace the entire bottom portion of the laptop, or at a minimum replace the touchpad and the piece to which it is glued.

¿ El touchpad salta mucho ?

Calibration problem ? Some laptops are much more susceptible than others.
