A:Answer How to check if you have an issue: The VBIOS will fail to update in the MyASUS application, the driver for the 6800M display adapter will return error code 43, and the GPU can melt, as you can see from the other reviewer's photos. You can also open the Radeon software and check if only the integrated Radeon display adapter appears. The IGPU will be the only functional video adapter, and that will offer generally poor performance.
If you are lucky and get a functional laptop out of the box, you may want to apply extra cooling (like a laptop cooling pad, at the very least) and so some benchmark stress testing to see if your liquid metal was applied well enough to withstand the test of time.
Good luck!
