My Alienware 17 had runs perfect with AC adapter. Everything are fine, but whenever i unplug the AC adapter. The fps dropped dramatically, it would only be 1/3 of the originally fps which means it's impossible for me to play any games without AC adapter. I had contact Dell, and they checked my hardware, there are no problem with my hardware. I have checked that the power option is always on :High performance. This is weird that my laptop has such low fps without ac adapter. I've tried many laptops with low configuration, and they even runs better without charger. Please help me to find a solution for it.

This is an easy fix. All you need to do is go to your Battery (Power Options), and set it to high performance mode. It will run the Dedicated Video Card all the time, until you select a different power plan.
