ACPI not detecting Laptop Battery Charge on Slackware 12
I have installed Slackware 12 on my MSI EX600 Laptop, and ACPI is not detecting my battery charge. I am notified if the Laptop is on AC or battery but the charge is always read at 0%. This is not my first Slackware 12 installation on a Laptop and I am aware that one is to include
I verified that these modules have been loaded through the lsmod command
and then enabled the battery icon display from KDE. I am using XFCE as well and I installed the xfce patch for the battery icon.
On this Laptop, I also have CentOS5.1 and Windows Vista, and the battery charge is detected by both. I peeped in the CentOS set-up and tried to mimic their modules and kernel setup but I did not find any important differences (yet?). Then I tried to look at the booting up messages:
dmesg | grep ACPI
and one line is particularly interesting:
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.SBRG.EC__.BAT1._STA] (Node c212257c), AE_NOT_EXISTI looked up the configuration files on CentOS: rpm –ql acpid and I compared them to the Slack’s files I listed from pkgtool.
Basically I have reached a dead end but I still have some things in mind, like downloading a Zen Walk Live CD and check if it detects the battery as well. I know Knoppix manages to detect the battery as well. The next step would be to install Zen Walk instead of Slackware, but I think that I would miss Slackware, so I would appreciate any hints.
