My netbook locks up after suspending while using the battery. It happened in the former version of Ubuntu and it is happening in Ubuntu 12.04. It is most discouraging to have to reboot. Anyway I found a fix for Lucid at pcurtis.com that worked. It used the gconf-editor to uncheck 'use_time_for_policy'. But 12.04 doesn't use gconf-editor. Is there a similar configuration in 12.04?

Have you read this post? Where do I set use_time_for_policy?. It is for 11.10, but the detail may help you find what you are looking for under the bonnet of 12.04.

Nope. I wish that had helped. It woke up once on battery but network manager didn't work. Suspended the machine again and then woke it up. The login screen came up and I signed in. Pressing return after putting in my password it locked up again. –  Tim Maddux May 6 '12 at 21:45
    
Okay think I might have found the answer at pcurtis.com/wind.htm#critical_power . It seems there is a problem with the Realtek wifi card configuration. At least the network came back up and it didn't freeze on waking. Hopefully it will continue to work. PCurtis deserves all my thanks for taking the time to write such a complete howto! –  Tim Maddux May 6 '12 at 22:03
    
Glad you found a solution. I had a look as the PCurtis site you mentioned, and yes, it is very thorough. –  Sun Dial May 7 '12 at 14:29
