Alienware M15x Runs Slower When Plugged In

On June 13, 2012, in technical stuff, by Necron99

This isn’t specifically related to Linux gaming – but thought I’d post the solution to this problem as it took me over an hour to find the right switch = wasted my time searching in Google!

Basically whenever the power cable was plugged into the laptop my gaming graphics slowed to unplayable… but when unplugged the games run fine… the opposite of what one would expect!

I did find a lot of posts saying to set the Windows laptop video power settings to Maximum performance etc – but that didn’t work – others said it was the adapter = NOT!

So after trying everything on every forum, I finally went into the NVIDIA control panel as a last resort and LO AND BEHOLD! = a separate setting for Power Management Mode under 3D settings… set that to Maximum and all fixed… sheesh, should have gone there first and not bothered with Google…

It appears the NVIDA graphics chip ignores the Windows power settings in favour of it’s own settings.

Hopefully this article will help others find the solution that worked for me = fixing the problem of slower performance and low framerates when their power cable is plugged in…

Game On!
