Reducing Component Power Usage to Avoid AC Adapter Short-Out

Hello all,

I recently had to re-install the AC/DC Power Adapter on my laptop, which involved taking the whole thing apart and soldering the new jack onto the motherboard. I'm now having a curious problem; when I play video games that are very taxing on the computer hardware-wise, my AC Adapter shorts out and the laptop switches to battery power (causing performance issues in-game).

The thing is, when I play less hardware-intensive games, the short-out does not occur. This leads me to the conclusion that as more power is demanded by the GPU and CPU (when they're under high stress), some threshold voltage is reached which shorts out the adapter. So, I'm trying to figure out how I would go about limiting the performance of my components such that they wouldn't hit that threshold voltage. Any ideas?
 
Well short answer is that should not be happening even if the laptop is under load. I am not sure what you could do to lower the power usage when you are playing games as that is when the CPU and GPU would be under the most load and there fore using the most power. What make/model laptop do you have?

I'm using an ASUS G53SW. Many users of this laptop have experienced the same issue as me, and I've read reports of people successfully re-installing the power jack without issue, but I suspect a poor solder job on my part may be a the root of the short-out issues.

In lieu of a direct, firmware-level power restriction on individual hardware components (assuming the tools to detect power levels are even built into the components, which now that I think about it, may not even be the case), I'm thinking that an indirect solution might be preferable.

Is anyone familiar with the nVIDIA Control Panel software, or the analogous software for Intel CPU's (if there is such a thing)? After poking around in the NCP a bit, it looks like I might find a solution in there, but I'm not familiar enough with the software to say that for sure.
