Baixa autonomia de energia

Olá a todos! Estou fazendo uma total migração para o Linux, pois estou usando meu notebook apenas para estudo Front-End Web. Enfim, troquei o Windows pelo Ubuntu 14.04, já instalei alguns programas(GIMP, Atom, Inskcape, qBittorrent e VMware Player 12) além de instalar o TLP para gerenciar energia. Meu problema que mesmo não executando nada, a previsão de autonomia da bateria é de 1h30min. Já pesquisei sobre o assunto, mas basicamente só há posts para a instalação/desinstalação do TLP. A matéria que usei para instalar o TLP é esta:

A configuração do meu notebook segue com o status do TLP stat:

Bom dia.
Tem algo errado com teu powersave. Em idle ele não deveria passar de 48ºC em média.
Como tá a parte CPU_MIN_PERF_ e CPU_MAX_PERF do teu TLP?
Segundo, o status de política de economia de energia scsi_host também tá em max_performance.
Aí não tem bateria que aguente.
Além disso:


Tua bateria já está em meia vida. Esse notebook deve ter mais ou menos 1,5 anos de uso comum, chutado.
Segue status da minha bateria:



Só remover uma ordem de grandeza. O powernow não faz sentido porque tô conectado no AC.

Pra gente começar a trocar figurinha, faz um teste pra mim por gentileza.
No teu terminal, com o AC conectado, manda:


(deve retornar enabled)

(deve retornar AC)

(deve retornar algumas linhas com uma frequência para cada core)

Copie todos os resultados em ordem, depois faça o mesmo teste com a energia desconectada.
Isso já vai ajudar a gente a ver se o comilão do teu processador tá pegando mais da panela do que o governor socialista permite.
Além disso, confirma se teu SATA_LINKPWR_ON_ (AC e BAT) tão com a configuração correta (min_power no BAT, max_performance no AC). PCIE_ASPM_ON_ também (powersave e performance).

Obs: Demorei a postar pois estava sem internet.
Obs2: Vi uma materia sobre placa hibrida( intel + nvidia) e consegui colocar o consumo de bateria em autonomia("powersave"). Os numeros acima já são com essa modificação
