So i have a Lenovo ideapad Z410 laptop and it has a built-in battery. It speed is 3.00 Ghz while but when I play games without charger (on a plane for example) it drops to 0.78 Ghz so I cant play games when ever I'm travelling any solution?
Check the bios and see if there is someting there or your graphics card software. Maybe there is something enabled that is slowing down your pc when it is not plugged in as to save battery
