I've seen in various postings that there is a BIOS issue with this
machine. I suggest making the early resume force a BIOS video POST and
see if this fixes it. To do so, do the following:
1. modify the kernel boot parameters as follows:
open up a terminal: Applications->Accessories->Terminal, then edit the
grub (bootloader) default settings file:
sudo gedit /etc/default/grub
..and change the GRUB_CMDLINE_LINUX_DEFAULT setting to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=s3_bios"
2. Now run update-grub to pick up these new settings:
sudo update-grub
3. Reboot
4. Try suspend/resume, see if this helps and let us know what happens.
