If no boot sound is played, but the machine boots normally and has audio, it is possible that the user has changed the default boot volume to 0. While the boot sound is playing, a user can adjust the volume using the ''volume adjust'' keys. This modified volume setting is saved and used for future boots. Try increasing the volume right after starting the laptop a few times, and see if the boot sound returns. |

Este es la sección de la Guia Diagnóstico para el laptop XO para el diagnóstico de problemas de encender un laptop XO
Bienvenidos
Para una introducción a las diferentes opciones de arranque seleccionable cuando el laptop se enciende, vea los Códigos Trucos.
Todas estas pruebas de suponer que dos fuentes de energía conocidos buenas son disponibles: una batería cargada y un adaptador de corriente. Para depurar problemas con la fuente de alimentación y carga de la batería, consulte Problemas de poder y batería.
Prueba con regularidad que el adaptador de corriente y la batería utilizados en estas pruebas están trabajando bien. Esto puede hacerse fácilmente utilizando otro laptop. Un laptop puede ser incapaz de poder solamente de su batería o adaptador de alimentación (por una serie de razones).
Para empezar, presiona el botón de encendido durante un segundo.
¿El LED de alimentación se enciende?
Cuando el poder se pulsa el botón una vez, y el LED de alimentación no se enciende, verifique lo siguiente:
Por favor, intentar restablecer el controlador incrustado. Preste atención a la LED de batería cuando retornas el poder. Debe flash naranja momentáneamente (aproximadamente un cuarto de segundo). Si no lo hace flash, entonces el Controlador Incrustado no funciona correctamente, y la placa madre debe ser cambiada.
En estos casos, el Flash chip del Controlador Incrustado debe ser sustituido como el primer intento de reparar la placa madre. Véase como cambiar el Flash chip del controlador incrustado.
Si el LED de alimentación no se enciende, pero el laptop iluminar la luz de fondo e incluso de arranque, el problema puede ser cualquiera de los indicadores LED ellos mismos o el conductor de alimentación LED (Q39, DDTC144EUA). Los LEDs están en serie, lo que si uno falla ninguno va a enciendir.
En raras ocasiones, el botón de encendido se convierte en atascados mecánicamente. En este caso, la computadora no detectar la depresión del botón de encendido, y no se enciende. Asegúrese de que el botón de encendido se mueve libremente.
Insertar foto de 'pegada' botón de encendido vs' desatascar 'botón de encendido
Si la batería LED destellaban en la restauración del poder, el botón de encendido no está atascado, y no otros signos de vida se detectan, entonces el tipo de falla es desconocida. Cambia la placa madre para arreglar el laptop.
¿ Se activa la pantalla ?
El LED de alimentación indica que el Controlador Incrustado ha permitido poder al CPU. Open Firmware (OFW) comienza la ejecución. El siguiente paso visible es encender la pantalla. La pantalla LCD debe ser inicializado con blanco, entonces empieza a mostrar texto o gráficos. La retroiluminación de la pantalla debe estar encendido, incluso si la retroiluminación estuve apagado.
Si esto no ocurre entonces la secuencia de arranque no está llegando a Open Firmware, o OFW está choqueando en una fase temprana del arranque. La manera de decirle es mirar a la actividad del LED de micrófono. El estado natural del LED de micrófono es iluminado. Uno de los primeros acciones que Open Firmware hace es apagar el LED de micrófono. Si ambos el LED de alimentación y el micrófono LED estan encendido, entonces un grave error de arranque se ha producido. Es necesário sustituir la placa madre.

This usually indicates a broken motherboard or a Real Time Clock battery problem in conjunction with early firmware. Some machines in our early production runs (before Jan. 2008) both had a problem with the Real Time Clock battery holder and had a version of Open Firmware (earlier than Q2D07) which locked up when it encountered a reset clock. The problem and its solutions are discussed elsewhere.
Escuches el sonido de arranque
If the display doesn't initialize, but the boot sound plays, then this is probably a problem with the display. See Display Problems.
Laptop arranca normalmente, pero no escuches el sonido de arranque
If no boot sound is played, but the machine boots normally and has audio, it is possible that the user has changed the default boot volume to 0. While the boot sound is playing, a user can adjust the volume using the volume adjust keys. This modified volume setting is saved and used for future boots. Try increasing the volume right after starting the laptop a few times, and see if the boot sound returns.
If no boot sound is played, and the machine boots normally but has no audio see Audio Problems.
The display remains blank
The display is active (including backlight), but no text or graphics appear.
This is typically a problem with the Embedded Controller's Flash ROM. It can be caused by removing power to a laptop while it is upgrading the firmware. In the field, the motherboard should be replaced.
- This diagnosis may be verified by connecting to the processor serial port (J1) and watching the early Open Firmware boot process. In some cases, it may be possible to manually reprogram the EC Flash from a USB key. In other cases, the EC Flash will have to be replaced.
The display says "Connect to power to proceed"
Not quite the correct wording. Anyone remember the exact words ?
Early versions (before Q2D14) of the firmware would stop execution if a firmware update was scheduled, but two sources of power (a battery and a power adapter) aren't present ( Trac ticket #5422). If this is the problem, provide both sources of power and reboot. The laptop should proceed with a firmware update and boot normally.
The display is showing an XO icon
This means that Open Firmware has started the boot process.
You can see much more information from Open Firmware by holding the '✓' (check) button (above the power button) after powering on. That will make Open Firmware display more detailed messages about what it is doing during the secure boot process (including early boot messages from the Linux kernel). The messages are in English only.
XO icon with a serial number and three icons below it
If the laptop powers up, but stops when displaying the XO icon in the middle of the screen, followed by a serial number (e.g. CSN74902B22) and three icons (SD disk, USB disk, Network signal strength), it is looking for its activation lease. This should eventually print "Activation lease not found" at the top of the screen and power-off soon thereafter.
The solution is to re-activate the laptop. Obtain a copy of the lease (or a new lease) from your country activation manager, place it (named "lease.sig") on the root directory of a USB key and boot the laptop. See what to do with your activation keys.
XO icon with a "sad face"
This means that Open Firmware couldn't find a signed operating system on the internal flash memory. (It will also look on USB memory sticks and SD cards.)
Try upgrading or re-installing the software.
XO icon with a single dot below it
If laptops powers up, but stops when just displaying the XO icon in the middle, with a single dot below it, it means that something is wrong when the Linux operating system starts operation.
This happens for a number of reasons, such as NAND Flash being full (Trac ticket #5317), user "interaction" with the operating system or a hardware problem with the NAND Flash ROM. The suggested solution to try is upgrading or re-installing the software.
If this has happened to the same laptop more than one time, it may have a Flash block that has gone bad.
Dealing with Bad Blocks on NAND
If you suspect that some NAND FLASH blocks have gone bad and you have a developer's key, you can ask Open Firmware to check the NAND FLASH and add newly-bad blocks to the "bad block table" that tells the system not to use them.
If you are using Open Firmware Q2D16 or earlier, the procedure requires that you type a few lines because of a firmware bug:
ok dev /nandflash ok : xx dup aa ; ok patch xx aa full ok dend ok test /nandflash::fixbbt
If your Open Firmware is newer than Q2D16, you don't need the first 4 lines; just type the line that begins with "test".
This procedure takes several minutes, because it tests every block on the NAND FLASH with several data patterns. The procedure is "safe" for good NAND FLASH, because it saves the previous block data before the test and restores it afterwards, so you won't lose any data on good FLASH blocks. There is, however, a small chance of data loss in the event that a block goes bad during (i.e. as a result of) the test, preventing restoration of the previous contents.
