Hello,
What can I install (or if the live dvd came with anything) to be able to see my laptops battery percentages? |

For Gnome, the default install includes gnome-power-manager, which when set right, puts an icon with charge state on your bar.
For CLI, acpitool in sys-power/acpitool will also report battery state. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD

almost all DEs has battery monitor, we need to know what DE are you using. _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |

I am using KDE, I am running a fresh install where I copied the live dvd to my system, (not a net-install or minimal install)
acpitool output:
Code: | acpitool
Battery status : <not available>
AC adapter : <info not available or off-line>
Thermal info : <not available>

This would imply your kernel does not have ACPI battery support or you don't have the modules inserted. I tend to compile ACPI into the kernel as it seems to be fairly important to a lot of machines (for the "C" of ACPI).
First off before we go off track: what brand/model machine are we dealing with?
I only have worked with PC/x86/x86_64 ACPI BIOS which works correctly for most modern machines. All other systems, I have no clue... The "other" systems includes laptops whose ACPI BIOS/DSDT are programmed incorrectly and Linux's ACPI interpreter breaks on their firmware... _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD

Hey I didn't think of that, I can re build it with ACPI enabled.
*edit*
Rebuilt kernel with ACPI modules, working as expected! Thanks |

Great!
Yeah it's unfortunate, the ACPI interpreter adds one heck of a lot of bloat to the kernel (did you notice your kernel size blow up?) It's huge... But I need it anyway for the "C" or Configuration part. Most newer machines with multicore or multithread require ACPI for Linux to use them anyway, and there are other stuff... _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD
