Y570 - Why do games run better off my battery and choppy when its plugged in?

[jackcnd]

Hey try to disable other keyboards in (region and language settings) except for English, because while in game, laptop might switch to other input keyboards such as Chinese. It worked for me after I disabled sogou pinyin.

I find it quite miserable for  Lenovo not being able to identify and solve this problem for this long. The most amusing part of the scenario is that tnone of the so-called "solutions" don't work except for limiting the cpu (which means disabling turboboost, a feature you've paid for). 

I wish I was aware of this problem before buying this laptop.

And yes, I also will never buy a Lenovo again!

I got Y570 for the purpose of gaming just a couple of days ago, BEFORE i read this thread.

Hope my laptop will not have this issue

Does this problem effect the Y470? So far no such issue on mine, but I only play SC2

Hello

Same problem here... "solved" by setting the CPU to 99%.

Lenovo seems to ignore this problem as no final cause and solution were made public.

Is any Lenovo official reading this topic? Or should we send our complains to Lenovo on other ways?

That solution barely does anything, it only improves it by a fraction.

yes, i still have the lenovo power management installed. Anyway when I change the power plan in windows or Lenovo Power Management, the change affects the other program as well. I select the "High performance profile" from windows and in the advanced settings I set both minimum and maximum processor usage at 99%. Note that when changing to other power schemes, or running on battery these values are set to defaults and you must set them again to 99%.
