The low benchmarks only occurred when I had the laptop battery removed and the AC adapter plugged in. Otherwise, everything works well with the battery connected.

For some reason, the battery also needs to be plugged in for it to work. It doesn't work with just the AC adapter plugged into the laptop.

Got it working. I had to boot the laptop with the egpu plugged in first, then disable the egpu from device manager and unplug it. Then I hotplugged the egpu back in and enabled it through the device manager. 3Dmark06 went up to 19924. I guess having the egpu plugged in when booting decreased the TOLUD size, allowing for hotplugging?

I have the latest bios flashed, and both the igpu and egpu show up on the device manager. Hotplugging the egpu results in a code 12 error. The Tolud appears to be dyanamic (the memory address is 00000000CFA00000). Should i perform a DSDT override?

I was able to connect the gtx660ti to my thinkpad x230 with a pe4L 2.1b + E2C2 and a corsair 600W psu. I installed all of the current drivers on to the hard drive (the operating system is installed on to the msata ssd). The gpu is connected to an external monitor and it seems to be working okay. GPU-z is showing a 1x 2.0 connection, but I am getting a 3dmark06 score of ~7800 and 3dmark vantage score of 8947, which appears to be low. From what I read on the forums, that would indicate that optimus is not enabled? Should I have installed the drivers onto the ssd?
