Linux Laptop Boot Battery Optimizations
Boot Optimization use sudo systemd-analyze critical-chain to get the most time consuming services. If you don’t need those services just disable them by this command sudo systemctl disable service-name.service and replace the service-name with the name of the service you want to disable.
BIOS Optimization Just disable any feature you do not use such as fingerprint scanner. To reboot into your BIOS settings, use this command sudo systemctl reboot --firmware-setup.
