IBM ThinkPad Digital 2000 Diagram
Estimado Digital 2000,
Los códigos de errores 163 y 173 para los IBM ThinkPads significan que el reloj en tiempo real no
está funcionando y la memoria CMOS/NVRAM tiene problema. Esto indica que la batería de la
CMOS está mal, sin carga. Hay que cambiarla y reiniciar los datos de la CMOS (día, hora, etc) en
el setup de la máquina..
No sé cual es el modelo de su ThinkPad, pero algunos de los modelos necesitan que usted, ao
prenderlo, mantenga la tecla F1 presionada para entrar al setup (claro está, después de cambiar la
batería interna de la CMOS…)
Véase una relación de los códigos de errores de IBM en las páginas siguientes:
163 CMOS error; Clock is not updating
173 Bad CMOS/NVRAM checksum

For their PS/2 systems, IBM used a system of diagnostic codes to diagnose
trouble spots in a given computer. The problem was, these diagnostic
codes were never really documented all that well. The codes that I am
presenting here are from documents I have read through, found on the web,
found in old books, documents and technical papers. As a computer
technician, I rely on documentation to guide me through these types of
messages. Therefore, I hope to provide this to all those other technicians
out there who get the opportunity to work on one of these. And, yes,
people still use them and some refuse to give them up.
The method for reading these codes is pretty straight forward. The first
part of the error code indicates the device that is causing the trouble. The
second part gives the meaning of the error. You can think of the first part
as the test code and the second part as the fault code. A fault code of 00
indicates that no problem was found. Thus 200 means the system memory
was tested. The 00 means that no fault was found. 201 would mean a
memory error. 202 would mean memory address error; lines 00-15.
This page is rather extensive and will be updated on a regular basis. Like
all the other codes out there. If you know of any error codes that I am
displaying incorrectly or that aren't here.
Let me know and I'll get it
corrected as soon as I can.
Thanks to Mike Rose for erors 129 and 229!
