Is there any reason not to suspect that the PE4L chip has gone bad in my situation? It was working a couple of months ago, then I let it sit for a while and tried to turn it on - no luck. I did perform a BIOS update in between then and now, but I'm not sure that this would completely prevent both Setup 1.x and Windows from detecting the card. I tried various combinations of the jumper switches and tried connecting to an older HP laptop - nothing detects. I don't have a desktop to test the video card in (a GTX 570HD) but I wouldn't expect the graphics card to have died. Voltages on the power supply seemed within specifications when I tested them with a multimeter. If it is the board, does BPlus have any sort of warranty? I know if it's the card EVGA will warranty it.

So, I'm continuing to try to debug my egpu setup, but still no luck. It seems likely that the PE4L is dead, but it seems odd that it would die while not being in use. Does anyone happen to have what the proper switch settings are for this board (v 2.1b)? If I can get it back to defaults I can try it in another laptop. I was trying to see where the fault was on the board, but the schematics seem to have some mistakes in them. Power Supply voltage is fine, video card seems fine (again, I don't have a desktop handy to try it with but when I put in an older video card in the unit it still doesn't detect), but Setup 1.x just says nothing is detected. I would appreciate any help, since replacing this unit is a little pricey

Hello everyone! So, I originally was on the DIY eGPU thread over at NotebookReview, but it seems it's all moved over here. For the longest time everything was working well, but now I can't seem to get my computer to detect the eGPU. I am using a Dell Latitude e6420 with a EVGA GTX570 HD on the PE4L 2.1b. At first I thought it may have been an issue with the latest BIOS patch (A16), but I tried it on an old HP notebook (Core2Duo) and Setup 1.x still doesn't detect it. The video card turns spins up and lights come on with the PE4L unit. Is there any way to easily diagnose whether or not the PE4L is the problem? I don't have a Desktop handy to try my video card in anymore. I tried playing with the PERST delay values per the Setup 1.x instructions, but no luck. As far as I know the unit has been off for a couple months since I last played Fallout New Vegas (and it was working perfectly well back then). Thanks!
