I have the same problem. System freezes completely once I plug out the power supply. And also if I start system without power supply it freezes once the Wi-Fi network is started. I can do nothing except hard shutdown.
My laptop: DELL XPS 1340 Nvidia G210M Ubuntu 10.10 Please help. -- System freezes when battery powered https://bugs.launchpad.net/bugs/605967 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
