WMAcpi is a software program that adds ACPI support to the WMApm 1.1 port. It allows for enhanced power management capabilities to monitor and regulate system performance.
The only difference between version 1.1 and 1.2 is the inclusion of ACPI support. Therefore, if you are not interested in ACPI, this version of the software is not for you. However, if you need ACPI support, give this version of the software a try and let us know if it works for you.
Before using WMAcpi, it's important to note that the software makes a couple of assumptions. These include having only one battery and it being a "Control Method" battery. Your ACPI BIOS also needs to be in working order, and the software is only tested with kernel 2.4.2. It's crucial to have this kernel to use WMAcpi.
Installation is easy, just follow the instructions provided in the "INSTALL" section. Make sure to update the Makefile to include -DACPI. If your system doesn't have ACPI, there's no need to use this version of WMApm.
For now, this version of the software only supports laptops with one system battery. However, the developer is working alongside the kernel ACPI community to standardize power reporting interfaces. Once complete, WMApm will be updated to support any battery number and provide full information about ACPI power sources.
