Why do games lag when off AC power?

Ok so the notebook is an E1505 with a pentium dual-core 1.73ghz... now I know about speedstep but I have it set to Home/Office desktop.. and it shows that it's still 1.73 on battery power but in games it lags a lot... why?

 

because it probably drops the clock speed of your graphics card as well.

 

ahh that might be it
so how do I fix that? or can I?

 

Check the video card settings, there will be an option for what to do when on battery power.

 

i don't know, i'm an ASUS owner. wait untill someone that owns the E1505 turns up and hopefully they can be more helpful.

Actualy it is also on your power settings and configuration.

Most notebooks have different 'settings' (normal, top performance, text editing) to give some examples.
These settings (when at default) are changed when you are plugged on AC adapter or not. When you are, they tend to go on Maximum settings, when you aren't they go on lower, power-saving settings.

You can change this very easily, you mostlikely have a power managment bloat-ware installed. If not, I think you can configure it in

Start => Congifuration => performance and settings

 

thanks, I found it, I think
