i think if you can remove the graphics card it will default to the cpu integrated graphics, but i do not know much about laptop hardware. i would just open it up if you feel comfortable doing so and don't have a warranty, and try to remove the gpu if possible. it should work without the gpu at least until you can get a replacement, if you even need a replacement, it just depends on what kind of computing you do. that's probably what i would try. hope this helps and good luck!
Good idea, I also though of this, but it does not appear that the graphics card is "pullable", when searching the service manual for the laptop, I had a look around and could not figure out where it was, it is probably soldered to the motherboard, in which case I have to somehow disable it in software.
