The results you gave from /proc/acpi/battery and from HAL seem consistent to me. It clearly indicates that once the battery charged your laptop stops using the AC and works on battery. Did you notice anything that can actually confirm this ?
It looks like a hardware bug or a BIOS misconfiguration. We could as well suspect the Linux kernel. Do you have any other operating system you could try on ?
