My laptop is a Vaio VPCF11M1E, running Ubuntu 10.10 64-bit.

After being suspended, I press the power button to wake it up, but it restarts the machine and I lose all my work. I do not have the same issue under Windows.

But hibernating works.

This worked for me on Ubuntu 10.10 before I installed ATI drivers

Edit the file /etc/default/grub (as root)

Change the line with:




run update-grub (as root).

This worked just fine after installing the ATI drivers:

I've solved a similar issue (reboot on resume) with a Sony Vaio VGN-FW51ZF by changing the last line of the file /etc/acpi/ from pm-suspend to pm-suspend --quirk-radeon-off (guess it was a problem related with ATI proprietary drivers)."

So thanks for those tips and I hope this save you some time. I'm about to do the same on my Ubuntu 11.10 I'll let you know if it worked!

Did not worked on Ubuntu 11.10 it still reboots instead of resuming :(

Welcome to Ask Ubuntu! ;-) We're very sorry, but this is not a good place to put another question as the only people seeing your "answer" will be the original poster and a bunch of reviewers trying to review your "answer" for quality... So please first look over the existing answers and if none of them work, ask a new question and refer back to this question and explain what went wrong. ;-) – Fabby Sep 29 at 23:00

If you have grub2 you should run sudo update-grub2 (run both just in case)

It's not necessary to run sudo update-grub2 if you're running sudo update-grub. update-grub2 is just a symlink to update-grub ($ file $(which update-grub2) /usr/sbin/update-grub2: symbolic link to 'update-grub'). Running update-grub2 in a system that only has GRUB2 (including Ubuntu 9.10 or later) will always be equivalent to running update-grub. – Eliah Kagan Jun 15 '12 at 2:42
