Working on Acer Aspire 3 (A315-59-556F) #97
Description
So I tried this on my Acer Aspire 3 laptop after battery calibration. At first, I thought it did not worked because my battery did not discharged to 80% from 100% (since I just finished recalibrating) so I had to manually discharged the battery (by removing the AC). Then, the terminal just said Skipping BTF generation for acer-wmi-battery.ko due to unavailability of vmlinux on installation and I don't have any idea what that means (I'm still a 2 months old Linux user).
The logs are as follows:
hexer@pop-os:~$ sudo apt install build-essential linux-headers-$(uname -r) git
