Hey all,

Have been using a W520 and GTX 660 for almost 3 years and it has been great except for one quirk.

If I use the Nvidia R331 (331.82-desktop, from November 2013) drivers then I am able to sleep and resume fine.

Newer drivers work fine (as in I can boot, play games, do everything normally) but the system will not resume from sleep. The system sleeps fine but when I try to resume the eGPU never wakes up. Even the laptop screen (iGPU) stays blank, though I can see the HDD activity LED flashing away.

Any ideas why?

Edit: Running Win7 64 bit.

I've been running a ThinkPad W520 with an Nvidia GTX 660 via a PE4L 2.1b for over a year now and it has been great.

I'd been using the R331 drivers for the entire time but recently I tried to update to more modern drivers and tried 344.75, 340.52 and 337.88. All work fine from a cold boot but all also have the same problem that when I try to resume from standby the GPU seems to not wake up.

When I power on the PE4L red LED turns off so it looks like it's talking to the laptop but neither the laptop LCD nor my external LCDs get any signal. Eventually I have to hard power-off the laptop and restart to get back to a working desktop.

Does anyone know why this would be?

Is there something special about the R331 drivers?

This may or may not be related but I also noticed that when I remove the eGPU ExpressCard and cold boot Windows can also no longer see my dGPU despite it being detected in Setup 1.3x (and not specifically disabled).

For the issue of only the eGPU appearing in the selection list, can you advise which version of Setup 1.x are you using, inc the installation binary filename eg: test1? Can you run save diags->compact_fails, archive the resultant \diags folder, upload to mediafire.com and send a link for analysis?

1.20 test7 is the archive I have (I'm Yun btw )

FYI I did this before I fixed up my startup.bat as instructed below. I also didn't run pcitools as I tried once and it seemed to freeze, although maybe I wasn't patient enough... if you need the pcitools output please let me know and I will try again

Your problem otherwise may be tied to using a PE4H 2.4 rather than a PE4L 2.1b or PE4H 3.2. PE4H 2.4 is only Gen1-compatible (pci-e 1.1). Meaning you should be doing a PCI Ports->Link Speed.G1 and adding it to your startup.bat, which will look like a 'call iport g1 [port]'.

THANK YOU so much, this was the problem!

I had set BIOS ExpressCard speed to Gen1 but apparently that didn't actually work... setting the speed using iport g1 worked.

Thanks very much for the guide gothic860

I followed these instructions with my W520 but couldn't quite get it working. Windows boots and detects the Nvidia GTX 660 correctly -- I can see it in Device Manager alongside my built-in Intel HD 3000 -- but I can't actually get it to display anything. If I use Fn+F7 to Extend Displays, the laptop display blanks briefly as if changing display modes but nothing appears on my external monitor attached to the GTX 660. Screen Resolution doesn't list any of the external monitors either.

Anyone seen this before?

Further details of exactly what I did...

I followed all of the steps exactly, except for the PCI Compaction - as my W520 is a Series 6 Setup 1.x warns me that I should disable the dGPU *after* PCI Compaction. I ran PCI Compaction with ignore=dCPU, selective compact for eGPU (it's the only option under selective; there is no iGPU+eGPU).

My resultant start.bat looks like this:

call speedup lbcache

call iport dGPU off

call vidwait 60 10de:11c0

call vidinit -d 10de:11c0

call

call pci

call chainload mbr
