With my Q702 setup I had issue with the indexer running when I switched to mobile and it would drain the battery. Win7 setup. Used the following to adjust its offending behavior: pause indexing on battery There's a group policy setting for this. Go to Start -> Run (or Winkey+R), type gpedit.msc. Navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Search. Enable the policy "Prevent indexing when running on battery power to conserve energy"
