I have a problem with my new laptop (Dell Inspiron 15R). It runs very slow and games become laggy when I unplug the AC adapter, even though I have the 'High performance' setting turned on. I use the laptop mostly for games and I don't want to have it constantly plugged it as I've heard it ruins the battery.
I've tried doing several things so far, like disabling the Intel SpeedStep in BIOS, changing all the settings to High Performance in 'Advanced Power Settings' and in nVidia control panel. Still, when I try to play games when on battery, they lag.
I'd like to know what are my other options to make games run smooth, and are they going to be harmful to the battery in any way? I don't mind the battery discharging quickly when I play a game, cause I can always plug in the adapter when the power is low. Although I don't want the battery to discharge quickly when I'm on the 'balanced' or 'power saver' mode.
I'd appreciate any help. Thanks!
