A few days ago, for some unknown purpose, I changed the configuration options of the battery, hoping to make the laptop battery last longer and last longer.
Later, I found that it became very slow to use! I didn't even think about battery settings. How did not understand, in the end is why?
Later, I asked a colleague and said that it might be a problem with the power setting, and suddenly realized. If it is plugged in and needs a high-performance notebook, it is best to choose Best performance.
One side effect of changing the power management is power consumption, and fan noise.
