I use PE4H with EC2C/expresscard, and want to use AMD Radeon 6670 2GB, DDR3 (there is no 6 pin power). My PSU is pure cooler master 500w. The problem: error code 12, but the unusal condition when my laptop is on the sleep, and I attatch egpu, the laptop can't back normal mode, and will sudden shutdown,just blinking on power button, then if i remove the egpu, it can be turned on. I've tried DSDT setting but it can't worked on my laptop, I wan to buy egpu setup 1x, and try to solve, but I got information that can't be sent to Indonesia, any idea? thanks
