Laptop videocard getts throttled far to much when not on ac power is there a driver or driver setting i could change to fix this.

My laptop has some serious performance issues when it is not plugged in.

I can go from 60 fps in game to 12 just by unplugging it. I fixed the issue with the processor underclocking it's self when not plugged in, but by checking the clocks on my card i saw that they too were cut by almost 3/4 clock speed. How can i fix this. Step by step would be great. I am running the latest nvidia drivers. and my card is a nvidia 8400gs

well... this is totally normal. You're laptop is designed to cut all 'unnecessary' power consumption features. 3D is off, CPU speed cut etc...

The only way i know that can help this. (not sure if its a total fix) is to download and install RMcock

This will stop the CPU throttling up and down. i.e. stay at 100%

You can even overclock it by setting the voltage higher. (only by 0.2500)

Settings:

"Advanced CPU settings" / processor

untick every box

"Advanced CPU settings" / chipset

enable pop up mode, enable C5 & C6, enable slow C4 exit

"Advanced CPU settings" / throttling

untick all

"management"

allow direct multi step transactions

sum of CPU loads

Set 'Maximal performance" profile

Lastly..Very important!! Set the state to custom and the higest available..

Eg. if your max voltage is 1.2500v /12 X multiplyer, then set it for 13.0X and 1.3000v

THen go to monitoring..

-CPU core clock and throttling should stay at 100%

-CPU frequency ID and violtage ID should be @ 1.2500 and 1.3000

all good?

EDIT: perhaps the most important, is to tick the box that says 'apply these settings at startup' : )

Worked like a charm. Should have searched before posting, although i didn't quite know this was my issue. This site has helped me out every time I have needed something. Many thanks.
