Sony Vaio FW350 reboots instead of waking up after sleep/suspend

Question

After I suspend and try to wake up my laptop it just automatically reboots every time. I had this problem in 11.04, but it happened occasionaly. Now I'm with 11.10 and it occurs every time.

It is a sony vaio FW350. It has an onboard Intel graphics.

I also have this other problem since 9.10: http://ubuntuforums.org/showthread.php?t=1448330 I guess they are related problems.

Solution

The fix provided in this link solved my problem:

1. You just have to edit the /etc/default/grub file:

   gksu gedit /etc/default/grub
   

2. Look up the line where it says:

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
   

   and change it to:

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=nonvs"
   

3. Save the file and close gedit.

4. Update the GRUB menu:

   sudo update-grub
   

5. Reboot and enjoy!
