Hello

I figured out that this problem was caused by no ACPI support.

To enable suspend, hibernation, screen saver and system shut-down you will have to force ACPI by parsing "acpi=force" to the kernel. To do that edit /etc/grub.d/10_linux and:
 A. at the beginning of the script declare new veriable (in example below it is called EXTRAPARM).
{{{
export EXTRAPARM="acpi=force"
}}}
 B. at the bottom of the script near line 155 insert new variable to look like:
{{{
"${GRUB_CMDLINE_LINUX} ${GRUB_CMDLINE_EXTRA} ${EXTRAPARM} ${GRUB_CMDLINE_LINUX_DEFAULT}" \
}}}
 C. run grub-update script
{{{
grub-update
}}}

I understand that this process would have to be followed also on other
older laptops with old BIOS.

Can this be incorporated into installation process so installer updates
grub configuration if old BIOS is detected?

many thanks

Dariusz
