Battery Charge Monitor on RH9

[Barry]

Hi All,

I am having problems with the Battery Charge Monitor 2.2.0 on RedHat 9.

The battery icon shows the battery as being un-charged even when it is fully charged. It also always displays it's self as running on AC power the whole time and not on battery power.

Any suggestions?

Maybe ACPI is not enabled?
Add to the end of the kernel perameters in the /boot/grub/grub.conf acpi=on...does that help?

Also what laptop? Everyone does something different with the power management on laptops. Check http://www.linux-on-laptops.com/ if your laptop is listed and see if anyone has had problems with power management on that or has fixes

If the "add acpi=on" suggestion doesn't work, try adding the following to the grub.conf file as kernel parameters:

acpi=off apm=on

You'll need to have the apmd package installed, and you can suspend to disk using apm -s, and to RAM using apm -S

Some BIOS have non-compliant ACPI implementations, so they just don't work ! If that is your case APM may work for you, or alternatively you could see if there's a BIOS update available for your laptop.

Or if acpi is enabled and acpid is installed and running make sure that your kernel is properly configured. I don't know about RH9 but in Mandrake 10 I had to compile the kernel modules and those included the acpi monitoring modules such as ac_adaptor, battery, etc. I then had to edit rc.modules to get those modules to load at boot time.

I had the same with the Gnome and GkrellM battery monitors - what I had to do was compile ACPI and the battery module (I liked the temperature one as well, though :D ) in 2.6.4. I don't know which kernel you use?
I don't believe I saw it in 2.4.
Hope this helps
