GTX 680M Battery Drain and Framerates

Recommended Posts

I have recently purchased the Sager Midern(9150-S) Clevo(P150EM) and noticed after benchmarking before draining battery and after draining battery that fuere was a 20 frames per second difference with Heaven by Unigine as the benchmarking software. Does anyone have an idea as to what may cause this difference in frames per second?

I'm not certain what scenario you are trying to describe, but sager(clevo) PSUs will turn off when their power output is exceeded, causing the system to run on battery. The system will only run high load for a few seconds on battery, but by then the PSU likely will have turned back on, preventing a system shutdown.

However haven is not very power demanding, so I don't think you will exceed 180W without overvolting and overclocking.

Another thing is that clevos will throttle the CPU under high combined GPU and CPU usage. This throttle can be prevented with throttlestop.

if you run Rivatuner, you can go into the advanced setting and keep the GPU's at max settings even when on battery. I did it once and by battery life went from a hour and a half to about 20 mins just surfing the web

I have a similar weird quirk where the battery wore down in mine really fast, and sometimes the clocks go crazy when plugged in and charging. Since the battery sometimes doesn't read as full even when it is, it just keeps pumping more energy in and I have to unplug before it overheats. I think I need a new battery, but is there anywhere I can get a cheap one?
