Description William Morgan 2003-11-08 15:11:58 UTC

/proc/acpi/ac_adapter, /proc/acpi/battery and /proc/acpi/thermal_zone are all
empty. dmesg has the following output:

As I mentioned in maillist, you must provide an ECDT manually. This machine 
lacks ECDT stuff.

Comment 3 Zhu Yi 2004-06-23 18:37:05 UTC

Shaohua, since we cannot resolve this bug from the software perspective, would 
you close the bug?

Comment 4 lkbugs 2004-06-23 22:09:54 UTC

Hmm. If this can't be fixed in software, why would windows be able to provide
readings for these? (comparisons to windows suck but... it still makes me wonder)

Comment 5 Shaohua 2004-06-24 01:21:11 UTC

Hmm, we have some workarounds for similar issues. Please check Bug 1744 and 
Bug 1690. Thanks.

Comment 6 Len Brown 2004-11-15 21:11:25 UTC

same in 2.6.9?

Comment 7 Shaohua 2004-11-15 21:15:56 UTC

There is a patch to provide fake ECDT if physical ECDT is absent in bug 1690, 
please try it. The patch works fine in my Tohsiba Laptop.
