Is performance supposed to crap out when running on battery?

[Feneant2]

I received my Dell 9100 yesterday and have been fiddling around with performance and such. I ran Aquamark last night to see what I'd get and it was around 27700. Today, I installed the Omega drivers and ran Aquamark on battery and I scored a ridiculous 13000. Is this normal, am I supposed to notice lower performance when running on the battery?

For those who are curious, the video card setting was ~ 201/187 for the mobility 9700 which is way lower than a pc version which is clocked at 324/310.50. I did not try to overclock it.

Have you checked to see if your lappy underclocks the proc while running on battery?

did you set the power management to max performance on battery?? If not, what you described is normal. all laptops are designed to "slow" down on battery power to max battery life.

Might have to do with power management, ill check into that. I notice that the screen is also dimmer on battery power.

201/187? Why so slow...?
The Mobility Radeon 9600 is clocked at approx. 300/200 stock. There is no way that the R9700 is slower. I think Dell underclocked your video card...

Feneant ...

First - Download SweedSwitchXP, set to Max Performance.
Second- Search in the Video Settings, there is usually an option to lower performance when on batteries. Disable that.
Third- "Fn + Up arrow " should increase your brightness

When laptop runs on battery, the whole system slows, not just the CPU. The system has a way to power down the bus to max battery life.
