During boot, the following > ACPI related messages appear: no. is is either apm or acpi. if you enable both, acpi will detect apm running and disable it, as far as I know. try disabling acpi completely and see if the battery then works. on T30ies, apm is still the way to go, acpi does not function properly enough yet. the interesting part is that you do not have other acpi issues, is that correct? does suspend, resume, hibernate, temperature, battery and throttle control all work for you, modulo the above errors?
