Monitoring Battery on laptop

podollb · 10-14-2003, 03:45 PM

How would I go about monitoring a battery in Linux for my laptop?
I know there are processes running (I think) that do that if I remember correctly but I don't know how to configure them so they warm me or notify me of status etc...

for ACPI you'll need acpid running, and then you can use gkrellm or other monitoring software ...
for apm you'll need apmd running and the same software would do just fine ... also depends on if the kernel was compiled with support for those technologies, or not ...

How do I add it to be in the kernel?

Yeah, I have redhat 9 and the battery monitor does not work. I am new to linux in general and just dual booting was a pain. I have kernel 2.4.20-8 and would like to enable? acpi(d?) on it. Any help in this would be great. Thx

I second that... (about how to get my battery monitoring daemon (acpid) running in my kernel)

Also if this concerns recompiling the kernel, what are some nice GUIs for configuring the kernel modules etc.

run APMD its less buggy and should work on almost any latop.

What is I have no APMD support in the kernel? How do I get it in there?

in redhat, since it should have the module compiled already, just type "modprobe apm"

no dice...

I just installed RH 9.0 and during the install chose EVERYTHING...

I just checked and apmd is set as one of the services running, but a ps -A | grep apm doesn't show it. Also if I just try to manuall start it it says no apm support in kernel. Any ideas how to add it to the kernel?

I you want ACPI support read the kernel compiling sticky in Red Hat forum, it’s the best guide I have seen so far. All you need to do is get the 2.4.22 kernel from kernel.org patch it with ACPI patch, which you can find on sourceforge, compile it and install it. Then download, also from sourceforge, and install the ACPI daemon (acpid). Once you have your new kernel up and running download and install i2c and lm_sensors. Both of those have great instructions included with them in the quickstart file. The longest part of this procedure is compiling the kernel and if you want nice GUI for configuring your kernel just use xconfig.

What is the link to the "kernel compiling sticky"?
