np9262 on battery, frames go to hell

Guys, I've had this thing for about 2 months now, and I love it (who doesn't). I just went out of town for a week, and subsequently, flew on more planes than I care to recount. At any rate, while on the plane, I notice video performance was lacking ISOs of DVDs, when played back, were jittery at full screen. Games that I can run at over 60fps on AC power were unplayable on batter power. I have checked my power settings under Vista Ultimate x64 edition, and I know everything in BIOS is manually set to never degrade performance. I don't really care if the battery only lasts 1/2 hour on battery if I'm gaming, I just can't figure out what options I'm not configuring properly to get to that point. Anyone else run into this?

Specifically, I tried playing Flatout2, just because it's dumb fun, and I know that this machine hould be able to rip that game into little tiny shreds, as it's not a tough game for my 4 year old laptop to play, yet the 9262 choked.

 

I'm having the same problem. Allthough the power settings is on high performance when running on battery. A 3dmark test on battery gives me like 1 fps on the first test :/

 

Well, duuh, on battery mode, the performance is pretty much less than half. There`s no point in playing on battery mode, you could get max 1 hour of playing.
If you must though, disable powermizer and set the system to Always on (XP) or High Performance(Vista)...

 

I agree with sabregen... even if the battery keeps you going for a short while, i would hope that the system would be giving me its 100% usual performance....

 

Here`s what I found on laptopvideo2go.com forums:
When installing the new driver :
-If you comment out in the inf file everything for the Powermizer settings you'll get a max of 800 something Mhz for the core clock/shader on riva tuner.
-if you comment out the PowerSupply settings than you get maximum frequencies.

I will make a guide to override the low level throttling on battery.

I use RMclock to force my CPU to go to full throttle on battery, and make sure Powermizer has max performance on battery... and use RivaTuner to force a full throttle for the GPU.

All of this gives me 30-40mins of full gaming... LOL... so I am not sure if its worth it, but its interesting to drain the battery that fast.

 

for me. when my card was oc'd the battery wasn't good enough to handle my notebook. the watt requirement was higher than the battery could provide.

it's not a hard thing to do to..

just disable powermizer.

and of course enable max preformance of proc.

in RMclock like gophin said.

no-brainer.

or.... just keep it plugged in. and when using on batery underclock and enable powermiser to get an extra 10-20 min out of batery

 

What battery are you using?
And would it matter what kind of battery it is?

I think the one I customized had a 12 cell lithium ion battery with regularly about a 1-2 hour battery life.
Would it still glitch?

 

All D900 notebooks have a 12-cell battery.

Yes, on normal use, I get about 1.5 hours of battery.

But if I force everything to full speed on battery (for gaming or rendering), it goes down to 30-40 min of usage.

 

I can probably change my clothes slower than that power drain...
