In the change advanced power settings, there's the intel graphics power plan.... right now it is set to balanced for me under both battery and plugged in.
Is it good to change it to maximum performance when plugged in and how would the laptop temperatures be goin' when my intel hd performs under maximum mode ??

Added on January 22, 2012, 6:46 pmHi,

I have a problem with my new laptop (asus n55sf). 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!

oh that sounds interesting, so i must use ac power when ever i'm gaming and most of the time my laptop acts as a desktop replacement and will be using it under external power plug in only. But what if the power suddenly goes off ... the laptop will immediately shut down without proper means and this can cause any damage to windows ?? Other than that i will be happy using it in ac power mode.

One more doubt pls, In the change advanced power settings, there's the intel graphics power plan.... right now it is set to balanced for me under both battery and plugged in.
Is it good to change it to maximum performance when plugged in and how would the laptop temperatures be goin' when my intel hd performs under maximum mode ?? and for the 3d settings should it be performance, quality or balance ?? Whenever my laptop runs on battery it automatically goes to performance and doesn't switch back to balance when ac power is used again...

yes, of course if we are on ac only without battery then if blackout surely we might lost some files that are currently in work(and probably didn't save of what), but with ac and battery to be used together, and if running on high demanding things(such as gaming), it will damage ur laptop even more. So if there is a plug or power source, normally i would prefer to take off the battery, so ur battery won't spoil so fast.

as for the maximum performance thing, don worry about the temperature. If u are just using for web browsing, movies, songs and all that ur temperature won't go very high one. The only moment u should worry about it is gaming. And so far this series's temperature quite ok, even extreme stress test also around 90+, and so far i don think any games can push the laptop til that extreme. For the 3d settings, it depends on u. For me i pick let my programme decide. And for the power plan, u just change from the power plan settings there, probably there are some settings overlap. Try check and see. And if me i would prefer to use high performance when on ac adapter and balanced/power saver when on battery only so that the battery can last longer

Hope this help 

guys how to reg our asus warranty ?

In the 3d settings thing, i'm talking about the intel hd card. I went to the graphics properties and then 3d... here there are two options. One is i can set the bar to either performance or quality or balance in between the two. I chose the balance one and others like texture quality, AF, AA and vertex processing are set to either default or application controlled. In my power plan settings, for this intel card i set it to maximum performance under ac power and balanced under battery.

Ok.. so u choose the high performance mode whenever u are on ac adapter, fine.. but i choose the power4gear entertainment and..... my power settings are like this : min processor state-5%, max-99% and for battery : min processor state-5%, max-80%.

Hope my settings for the intel card and power plan options are right.... and correct me if i need to change something anywhere.

for my n45sf needs example..
3d : quality and sometimes let the 3d application decide (depends on gaming needs)
P4G : default high performance (no adjustment)
always gaming with ac power plugged in while without battery.. faced black out several times but so far no HDD poblem ~ hd tune pro..
only use my battery for some important/low connection downloads.

yours is fine i guess..

question, do u face the problem me and nuttyking91 facing? Its like u half way play games, then suddenly the whole screen freeze and distorted sound starts coming out from the speaker non stop. Only way to stop it is to cut the power. Its totally random, but somehow i discovered if i play dotA(warcraft III) sure crash one

thanks for the advice...finally i can play PES 2012. I need to try NFS Run later to c da performance

lol hope it helps. And btw, NFS the run locks the game fps at 30 only, no matter what settings. I dunno whether this is coz i play *ahem* or what lol, but the fps just fixed at 30 only

manage to solve my keyboard prob..now got another problem, my lappy keep randomly BSoD..anyone know what might cause this?
