  1. I did what I could, and here's what I get:

    Notice the line "current policy". It should say "within 800 MHz and 2.7 GHz". How do I fix that?
    Not much of an idea on what info I should be providing, so I'll answer anything I can.

    Ok, I fixed this just now. Here's how:
    Terminal (Alt+F2) > sudo thunar (replace thunar with your file-manager)
    > / > sys > devices > system > cpu > cpu0 > cpufreq > scaling_min_freq
    > edit to the lowest value you want (800000 in my case) > save > ignore any failure errors > exit thunar
    > back to terminal > cpufreq-info
    TADA! It should be done now. In case you need to edit you maximum scaling frequency, replace Scaling_min_freq with scaling_max_freq.
