Comment:
I have the same problem: No battery status detected on Acer Travelmate 3000 (3004WTMi). The battery is (reported to be) smart battery, I am using 5.10 Breezy. My /var/log/syslog has rows like this: 
ACPI-0362: *** Error: Looking up [Z00B] in namespace, AE_NOT_FOUND
search_node dffe2620 start_node dffe2620 return_node 00000000
ACPI-0508: *** Error: Method execution failed [\_SB_.BAT1._BST] (Node dffe2520), AE_NOT_FOUND

A DSDT exists that claims to fix this problem:

Many Acers seem to have this problem. There are success reports with custom DSDTs:

Fedora Core 4 RPMs and success report:
