I upgraded one of my labtops with an desktop gpu adapter and installed a gpu on it. And it acutally works well i can game at full settings and have great framerate but im still using the battery on my labtop and i also have a power supply powering the gpu. So my question is, If i unplug the labtop charger to use the battery and for charging it. Will it effect the power supply from powering the graphics card. For example: ( Im runiing some games. My battery is fully charged. I unplug the charger and will it for some reason mess with the power supply and crash the graphics card?

While I have zero experience using an external GPU with a laptop, I don't see why (or how) it would crash the GPU if the GPU is being powered by an external power supply. It shouldn't disrupt anything. Though I'm not sure why you would want to do that, seeing how your will have to keep the GPU's power supply plugged in anyway.

*I suppose you would ensure the power saving mode doesn't come on, else it might reduce performance on battery.

This is how it works. The adapter is connected to the wifi chip in the labtop motherboard. So when the motherboard receives a signal thats wanting to power the computer. it sends a nother signal to the power supply giving the GPU power. It runs just like a normal desktop. So when the labtop gets shutdown the GPU and power supply power off with it ( What i mean is if i click shutdown and the motherboard shuts down. I dont need to unplug the power supply because that will be shutdown with the motherboard. Its 1 peice, not 2 which is nice because it makes it run like a normal tower )

Its a nice and very easy way to upgrade old labtops in to gaming machines in stead of spening $900 for a gaming computer
