Hi Fabio, That was on Ubuntu 9.10 Karmic. I decided to upgrade last night to 10.04 and the problem *seems* to have gone away. I will keep an eye on it for the next little while but if you'd like to mark this ticket as closed for the time being that would be fine.
As for the specs (in case you still need them): -Dell Studio XPS -P8600 Intel Core2Duo @ 2.40GHz -4GB RAM -AMD ATI Radeon HD 4670 Let me know if I can be of anymore help. -- Power settings do not switch when A/C plugged back in https://bugs.launchpad.net/bugs/654322 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
