Ubuntu 16.04 Superaquecimento do Skylake

Navegue suas respostas
2

Eu comprei recentemente um laptop embarcando um processador skylake i7-6700hq, e consegui instalar o Ubuntu 16.04, no entanto, notei que o laptop estava superaquecendo resultando em uma bateria muito curta enquanto no Ubuntu (1,5 hora enquanto ele dura 6 horas no Windows).

Então eu corri powertop , e notei que meu processador nunca fica abaixo do estado PC2 e, portanto, mesmo em estado inativo. Eu também tentei rodar powertop –auto-tune e mesmo se houver uma pequena melhora, o processador nunca fica abaixo do PC3.

Eu também tentei atualizar o kernel, passando do 4.4 ubuntu para 4.7, mas não teve efeito.

Para ser franco, sou completamente ignorante contra essa questão, é por isso que estou indo até você. Eu também estou anexando powertop output.

Obrigado pela sua ajuda!

Primeiro, atualize o firmware da placa-mãe para o mais recente e mantenha-o atualizado.

Em segundo lugar, instale o pacote intel-microcode (e você deve usar a versão 3.20160714.1 ou posterior, para obtê-lo do Ubuntu YY ou do Debian).

Certifique-se de ter o microcódigo 0x9d ou 0x9e após a reinicialização (em / proc / cpuinfo ou no log do kernel).

Isso ajudará alguns (pelo menos, deixará algum comportamento potencialmente fora do caminho), mas não resolverá tudo. O problema NVMe com o PC3 permanece, e isso requer um código que ainda não está no kernel do Linux, e possivelmente algumas informações sobre as quais a Intel ainda não contou a ninguém.

Como você tem um laptop com placa gráfica NVIDIA (provavelmente na configuração "Optimus"), ele pode compartilhar um dissipador de calor com seu processador e gráficos integrados.

Nesse caso, pode ajudar a instalar os drivers proprietários da Nvidia:

  • sudo apt install nvidia-375

Isso ajudou a corrigir problemas de superaquecimento no meu caso. Eu acho que uma alternativa seria usar o driver nouveau de alguma forma e / ou garantir que os fãs da placa nvidia sejam ativados.
