My system wakes up whenever I plugin my system to ac power. That is a really big inconvenience, since I hibernate my system usually. So a wake here means then system will turn on.

This happens despite acwake being set to 0. Even lidwake too is set 0, and I am able to turn on the system by simply opening the lid.
