  1. Event 4101 Display Driver stopped responding

    What do you suggest? I am not sure how I would test for this PSU issue without getting a load of PSUs and trying each one.
  2. Event 4101 Display Driver stopped responding

    I tried the tin foil to block any EM interference, there is a gap in the plastic below the mPCIe connector and if anything conductive like tin foil makes contact with the pins below the plastic then it shuts down the laptop and it will not turn back on unless battery and BIOS battery are removed and put back, so that is out of the question. Put the PSU power cable in its own socket, no extension. Now I also get "The 'NVIDIA GeForce GTX 660' device is not removable and cannot be ejected or unplugged." when trying a game I know to cause problems with the egpu. Remembered that I used another PSU in the past, still had the same issue. No USB devices are in the EXP GDC to cause interference.
  3. Event 4101 Display Driver stopped responding

    The yellow 12V line has 16A, I had tried with another PSU in the past and it made no difference.
  4. I have Lenovo e540 with an EXP GDC Beast 8.4d and a GTX 660. The nvidia display driver crashes with a black screen for a few seconds when launching some games or when the egpu is used for a while, it sometimes will recover My external power supply is 350W and the card has a power consumption of 140W so I do not think this is a power issue. "Event 4101 Display driver nvlddmkm stopped responding and has successfully recovered." What I have tried: A GTS450 instead of the GTX 660. Setting the PCIe port to Gen 1 in egpu setup. Setting the PCIe port to Gen 2 in egpu setup. Setting the Nvidia power management to maximize performance in the Nvidia control panel. Going back to the driver version 327.23, I got a blue screen instead of a crash when using this version. Disabling HDMI audio in the Nvidia control panel. Any suggestions or advice on this issue? Thank you
  5. Using a HD 7850, the e540 recognizes it with no errors but does not detect the external display. Did you have to do anything to get the external display recognized?
  6. Hello people of Tech Inferno. I am trying to get my laptop withing with an eGPU, i have: Lenovo e540 laptop, EXP GDC Beast 8.4d with mPCIe connector, Nvidia GTS 450, Power X3 450W PSU, eGPU setup 1.30 Initially I would get a black screen when trying to boot with the eGPU connected and when trying with plugging the mPCIe connector in during boot I got this error: "0187: EAIA data access error. 2201: Machine UUID is invalid." Connecting the GPU to an external monitor has no effect. I got around this by putting tape on one of the pins as per this post. After that I no longer get the black screen but windows 7 does not detect the GPU, the fan on the GPU still spins when the laptop turns on and there is a green light on the EXP GDC. I followed the guide on this post but I got this BSOD once rebooting after applying the DSDT override in step 2: "The BIOS in this system is not fully ACPI compliant. Please contact your system vendor for an updated BIOS. Technical information: ***STOP: 0x000000A5 (0x0000000000000006,0xFFFFFA80066BCD50,0xFFFFFA8007103CAB,0XFFFFFA80074FD340)" Does anyone have and suggestions or advice? Thank you in advance. UPDATE: Was able to get Win 7 to detect the GPU when swapping the mPCIe connector while in sleep mode but now I have error 12. UPDATE: Tried the DSDT override guide here but loading dsdt-modified.aml as a registry override causes a blue screen and setup 1.3 hangs when loading the dsdt-modified.aml as an in-memory substitution, it does not hang when the SATA mode is changed from AHCI to Compatibility but it is too fast for me to tell what it does and it causes windows to freeze on boot once it is done with no effect on memory for the next boot. Got it working, just trying to get the laptop to switch to the eGPU now.
