Cannot scale frequency of a Core i7 2720QM
- by user51414
I own a Dell Latitude E6520 with an Intel CPU (Core i7 2720QM). After installing cpufrequtils, I get the following message :
cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009
Veuillez rapportez les erreurs et les bogues à [email protected], s'il vous plait.
analyse du CPU 0 :
**pas de pilotes cpufreq reconnu pour ce CPU**
maximum transition latency: 4294.55 ms.
In English : no cpufreq pilot found for this CPU.
Thus my CPU runs always at full speed (2,2 GHz) which consume the battery and shorten its life. I don't either know how to activate turbo mode.
Please help ! Regards,
Al
