 |
|
On a Thinkpad T42p, 2.6.12 kernel, I boot with the dvd-rw in the ultrabay, then I hotwap it with the battery. The ultrabay battery is being discharged and charged just fine, except there is no /proc/acpi/battery/BAT1 entry, so the OS can't display correct battery stats (charge%, time left, etc). If I boot with battery in ultrabay, BAT1 is there any everything is reported fine, but I can't swap in the dvd-rw device.
Is there anyway to get the kernel to recognize (when I boot with dvd-rw) the newly swapped in battery? Do I need to compile the battery as a module and do a rmmod/modprobe when I stick the battery into the ultrabay? |

| You probably need ibm-acpi for the hotswapping to work right. You can look here and here for more information. |

I have ibm-acpi installed as well as the Thinkpad ebuild. The tpctl can recognize that there's a battery in the ultrabay, but there still isn't anything in /proc/acpi/battery/
Is it possible that the ibm-acpi scripts are configured incorrectly? |
