nMP - HP Omen Accelerator - TB3/TB2 adapter - won't start up
Connected to another Windows laptop with native TB3 interface everything works well. Device turns on, card is powered up and is recognized by Windows, etc. etc., as soon as the TB3 cable is attached.
Connected to my nMP however, nothing happens - looks like it is not initiated properly. Neither on most current High Sierra, nor on Windows 10 via external hard-drive.
How can I power up the eGPU with my nMP?
Any advice is much appreciated!
Are you plugged into bus 0? The 2 immediately above the HDMI port.

I had the same problem but with the Omen Accelerator and a Macbook late 2014 connected with the Apple Thunderbolt 2<->3 Adapter.
The Omen Accelerator never turned on no matter how it was connected or which cables where used.
I assume the Omen I got was delivered with an older firmware, not the latest 25.25. But I have no access to a Windows computer with TB3 ports at the moment to verify this.
Have you checked the firmware of your Omen on the Windows Laptop?
Yes, successfully updated the firmware yesterday via a TB3 notebook.
Also powered the nMP off for 20 seconds, did a NVRAM / PRAM reset.
Tried an NVIDIA 1070 today
Any further ideas?
What does the Thunderbolt tree in System Information look like? Does the light in front of the OMEN Accelerator power on when connected?
It says no device connected.
The eGPU case is not powered on. Red light stays off.
Unless I connect it to a native TB3 port, then the whole box starts up.
Could it be that the Omen accelerator needs too much power over the Thunderbolt port to be activated, due to the vast amount of interfaces it provides (eg. network, 4x USB)?
Apple states on their Thunderbolt information site, that the Apple Thunderbolt 3<->2 adapter only supports one powered Thunderbolt 2 device on a USB-C equipped Mac.
If possible, I'd say check the Thunderbolt 2 cable and Apple TB3-to-TB2 adapter to make sure they both work.
Thunderbolt 2 cable - tested - works
MMEL2ZM/A adapter - tested - unsuccessful:
- Booted the nMP in target disk mode and connected via adapter & tb2 cable to windows laptop. Adapter is found in device manager, but no disk is shown in disk manager. After some time windows shows "Unknown USB Device (Port Reset Failed)"
- Connected laptop to Sonnet Echo Express SE II box via adapter & tb2 cable. Device does not power up
Once I connect the nMP to the Sonnet box tb2 to tb2 the Sonnet powers up.
I did disconnect - wait - reconnect a few times of course to test.
Something related to the adapter, good guess itsage. Or a windows driver issue. The adapter is brand new. Somehow I feel this is a design / protocol issue, not a necessarily a hw defect. Unfortunately, I do not have a second adapter to test...
Edit: Also, connecting to an LG 34'' TB display did not work. Though the right source is selected the display still shows "no signal".
