In 2003, APM worked better than ACPI on the T21 and the T23.
In 2005 or so, I think ACPI was working fine on them.

Thanks, ACPI works well on the T23.
Indeed, it works well back to the T20:-)

My experience with old-laptops is:

1. hdd dies
2. CMOS battery dies
3. main battery dies

But from a practical view of runing a new distro on an old laptop,
the distros seem to drop the video support for the old controllers,
leaving you in VGA mode.  That is the case with the T23, which
has an S3 SuperSavage video controller.
