legion y730 drops in ghz

hey everyone,

well. i will lay off ALL the previous problems that the laptop came with (such as an unplugged touchpad, a broken charger and an absolutely horrific repairs i got).

my cpu seems to work at only 0.79 ghz and doesnt go up.  rarely it goes to 1.6 ghz. when unplugged.

when i plug it in it seems to work around 2.2 which seems normal but as soon as i start putting some load it just drops down. 

only thing which solves it for a cuple of minutes is if i go unto bios and load default settings then boot into windows, only then i get the boost speed of 4 ghz. temps are pretty normal (laptop is repasted witharctic mx4).

alldrivers installed windows 10.

what can i do guys really dont know.....

Hi,

Can you go to control panel->power options and check what power profile are you using?

Does the behaviour change if you switch it to "high performance"?

I should have mentioned it before.
The power plan does not seem to have any influence.
Also the max cpu usage in advanced options is 100%.
