Если ноутбук с Linux не всегда просыпается из режимов S3/S4 (Sleep), то можно попробывать так: http://iam.tj/prototype/enhancements/Windows-acpi_osi.html

VERSION="$(sudo strings /sys/firmware/acpi/tables/DSDT | grep -i 'windows ' | sort | tail -1)"
echo 'Linux kernel command-line parameters required: acpi_osi=! "acpi_osi='$VERSION'"'
config() { sed -n '/.*linux[[:space:]].*root=\(.*\)/{s//BOOT_IMAGE=\1/ p;q;}' /boot/grub/grub.cfg; }
echo "Existing Command Line: ` config `"
sudo sed -i "s/^\(GRUB_CMDLINE_LINUX=.*\)\"$/\1 acpi_osi=! \\\\\"acpi_osi=$VERSION\\\\\"\"/" /etc/default/grub
sudo update-grub
echo "Modified Command Line: ` config `"

Don't be put off by all the
characters. Those are required in order to allow sed to insert literal double-quotation marks into the GRUB_CMDLINE_LINUX string.
/etc/default/grub will have added the acpi_osi parameters to the GRUB_CMDLINE_LINUX so it will look something like this (there may be other kernel options that were added on some previous occassion):

GRUB_CMDLINE_LINUX="acpi_osi=! \"acpi_osi=Windows 2015\""

/boot/grub/grub.cfg will have these parameters added to every linux command-line, e.g.

linux   /vmlinuz-4.13.0-16-lowlatency root=/dev/mapper/VG_OS-ubuntu_16.04_rootfs ro acpi_osi=! "acpi_osi=Windows 2015" splash $vt_handoff

Once rebooted the running kernel command-line will show something like:

$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-4.13.0-16-lowlatency root=/dev/mapper/VG_OS-ubuntu_16.04_rootfs ro acpi_osi=! "acpi_osi=Windows 2015" splash
