When I close the lid of my laptop and open it after some time I am greeted with a message "Failed to suspend". When I tried to manually suspend/hibernate, I saw these options are not available there at all. Of course, they did exist when I did the fresh installation but I can't see them anymore.
I am totally pissed off with this. Please help.
Finally I was able to resolve the problem by installing acpi-support from the ubuntu software centre. Here is the thread that helped me http://ubuntuforums.org/showthread.php?t=1608752
I know you've solved this, but I want to mark it as answered in the system:
Installing acpi-support can bring the suspend/resume back, sometimes issues are fixed in kernel updates and sometimes (rarely) issues are fixed in a bios upgrade.
Had kind of same issues with my toshiba satellite. After wondering around for long time I ended up installing the new kernel 2.6.36 from here, http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/
It seems to have resolved the issues at least when I am suspending from command line sudo pm-suspend. If I close the lid still haven't figured it out why its not working.
