I have changed all the setting that related to performance exactly same as plugged in....jus some option that dim display , turn off display i leave it
i'm not sure all the setting same because i dunno every single place that need to set....but i did set high performance in my power option when using battery
I have a problem with my acer 5755g when i playing games with battery the game performance is very bad and laggy...although it is able to choose whether use intel HD graphic or NVIDIA high performance graphic but both also laggy....but...
