Just be careful with powertop's suggestions: it suggests min_power instead of med_power_with_dipm (https://lore.kernel.org/patchwork/patch/830838/ https://lore.kernel.org/patchwork/patch/830838/), which can lead to data corruption. It happened with me on my current laptop, I played a bit with powertop on it when it was new to see how long its battery could last, and ended up with filesystem corruption, so I had to wipe and reinstall; luckily, I didn't have any important data on it yet.
