Suggestion: Enable USB autosuspend by pressing the U key or adding
usbcore.autosuspend=1 to the kernel command line in the grub config
Podpowiedź: włącz zarządzanie zasilaniem łącza SATA ALPM przez:
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
lub naciśnij klawisz S.
Podpowiedź: włącz opcję noatime systemu plików wykonując poniższe polecenie:
mount -o remount,noatime / lub przez naciśnięcie klawisza T
noatime wyłącza stały czas dostępu do plików, który powoduje dużo operacji wejścia/wyjścia dysku.
Suggestion: Disable 'hal' from polling your cdrom with:
hal-disable-polling --device /dev/cdrom 'hal' is the component that auto-opens a
window if you plug in a CD but disables SATA power saving from kicking in.
