Sleep Mode

Note: If you have up to date BIOS and Gentoo system, you probably no longer need this. Also beware that updating BIOS after doing these steps would break your Gentoo installation, You'll either need to disable this or redo same steps for the new BIOS.

This family of laptops don't support Suspend-to-RAM mode and instead linux fallback to Suspend-to-Idle mode. In Suspend-to-Idle system can wake up from sleep significantly faster but also consume significantly more power while in sleep mode compared to Suspend-to-RAM.

This repo detail how to bring back S3 mode (Suspend-to-RAM) for Asus G14 and G15 variants. Note that while the repo's readme recommend updating your bootloader to load the patched `dsdt` file, it is also possible to include it into the kernel instead.

Software

Linux asusctrl

asusctrl is a commandline utility that allow configuring different parts of the system without root access.

user $asusctl
Optional arguments:
  -h, --help             print help message
  -v, --version          show program version number
  -s, --show-supported   show supported functions of this laptop
  -k, --kbd-bright       <off, low, med, high>
  -n, --next-kbd-bright  Toggle to next keyboard brightness
  -p, --prev-kbd-bright  Toggle to previous keyboard brightness
  -c, --chg-limit        Set your battery charge limit <20-100>

  led-mode   Set the keyboard lighting from built-in modes
  profile    Set or select platform_profile
  fan-curve  Set, select, or modify fan curves if supported
  graphics   Set the graphics mode (obsoleted by supergfxctl)
  anime      Manage AniMe Matrix
  bios       Change bios settings

asusctrl can be compiled and installed from this repo
