Çift önyükleme yapılandırmasında Ubuntu 10.04 ve Windows 7 Starter çalıştıran bir Dell Inspiron Mini 1012 var.
CPU, Windows boşta olsa bile Ubuntu'da olduğundan daha serin çalışır. Örneğin, şimdi Ubuntu'dayım, CPU bir süredir rölantide ve CPU sıcaklığı lm-sensors
ve C'ye göre 72 C'dir coretemp
.
Makine aslında bir noktada Ubuntu'da aşırı ısındı, sadece CPU'yu uzun bir süre% 100'de çalıştırmaktan. Yine, bu sorun sadece Ubuntu'da ortaya çıkıyor - Windows'ta bir ısı sorunu fark etmedim.
CPU hızımı 1GHz (1.67GHz yerine) ve Powersave moduna ayarlamak için CPU Frekans Ölçekleme Monitörü GNOME uygulamasını kullanmayı denedim, ancak bu rölanti sıcaklığını etkilemiyor gibi görünüyor.
İşte /proc/cpuinfo

Herkes CPU benim Ubuntu altında daha serin çalıştırmak için nasıl herhangi bir tavsiye var mı?

The program 'upowerd' is writing to file 'history-rate-DELL_2T6K207N-52.d' on `/dev/sda5`. This prevents the disk from going to powersave mode.
