The battery information is obviously only existent if there is a battery
plugged into
it. Power usage is only available if the laptop is running on battery.
If /proc/acpi/battery does not exist, have a look at
/sys/class/power_supply/...

Also, can you still post all logs I've requested? It helps me in verifying
behavior.
