Talk:Longer battery life

Extreme Power Management

Please clarify: does EPM only affect WiFi or does it also (as was stated in a previous version of the paragraph) additionally do the same power savings as the Automatic Power Management? It makes a big difference to me, as I'd like to have an "airplane mode" that actually saved some power without rendering USB, etc. useless. -- Davewa 20:22, 6 October 2008 (UTC)
