I think that it has to do with the "smart" energy management to ensure long lasting lifetime for the battery. In my case the performance of the laptop runs under 40-50 % of the full power when plugged in to AC power. <img class="lia-deferred-image lia-image-emoji" src="https://community.sony.at/html/@3191CA7235A406D833094BA2DD1CF2FF/images/smilies/011.png" alt=":slight_smile:" title=":slight_smile:" /><BR /></P></BODY></HTML> Mon, 20 Nov 2006 21:52:07 GMT https://community.sony.at/t5/pcs-accessories/q-notebook-fe31m-cpu-frequency-at-battery-operation/m-p/107582#M86827 Seawit 2006-11-20T21:52:07Z
