Hello everyone!
I'm trying to make my first eGPU setup as an inexpensive performance boost for an old laptop:

Laptop: Dell Studio 1555, BIOS A06
OS: Linux Mint 64-bit (Windows dual-boot)
GPU: GeForce GTX 560
Dock: EXP GDC Beast (Expresscard)
Power: 8-pin Dell DA-2

Sadly, I'm stuck. I assembled everything and rebooted the laptop, which got the fan to spin on the card, but beyond that when I run

lspci | egrep 'VGA|3D|NVIDIA'

my output shows that only the laptop's integrated Intel GPU is detected:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

So like I said, I'm befuddled. There are no options in BIOS to change any graphics selections. I tried with the ATX PW switch both ON and OFF and kept PTD at OFF. I also waited until after boot to plug in the Expresscard, with no change. There are two 6-pin connectors on the card; do I need to power one or both of those for the card to work at all? I would think if the fan is spinning that there is power and therefore it would be detected, but that's clearly not the case.

Thanks in advance for any suggestions; if there's no solution maybe it might be a sign to let this old laptop die and find something more capable, but I figured I'd give it a shot anyway.

Laptop: Dell Studio 1555, BIOS A06 | OS: Linux Mint 64-bit (Windows dual-boot)
GPU: GeForce GTX 560 | Dock: EXP GDC Beast (Expresscard) | Power: 8-pin Dell DA-2

hey~
I succeeded in installing on the same system.
The graphics card could not be seen in Device Manager and I had to patch the DSDT.
i had setup problem, but it works perfectly now.
check the link below. good luck~

That's good for windows, but DSDT isn't applicable to Linux. I think the boot parameters 'pci=noCRS' or 'pci=noacpi' or 'acpi=off' would be things to try.

Thank you both for the suggestions; I decided to go ahead and buy the 6 pin graphics card cable, and after plugging that in the card shows up in lspci! Of course for every step forward, there's two steps back. I followed the common instructions to add nvidia drivers:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update 
sudo apt install nvidia-390

When I rebooted, the GTX 560 showed the Dell BIOS splash screen, but the loading bar froze. I tried changing both the ATX PW and PTD switches and rebooting, but observed no change. After unplugging the Expresscard I could boot normally, but then the Nvidia drivers appeared to crash my Cinnamon desktop. I've purged those drivers and everything's back to square one again. I'm going to try rebooting to see if the included nouveau open-source drivers will work, but I'm not holding my breath. I'll let you know if there's any other improvement.

Hi

My Graphics card also isn't showing up in device manager. How did you know that you were getting Error 12 and needed to do the DSDT overide, or did you just guess that was the problem?

Thanks.
