    Y510p Ultrabay Graphics card

    Oh, I was talking about the connector that the gpu is inserted into, not the ultrabay one.

    The schematic looks good. I can't see any mistakes. Have a look at your PCB and make sure everything is routed correctly. One pitfall I could think of is the footprint for eGPU PCI-E connector. When you look at it from the top, with that smaller section facing up, the B will be on your left, and the A - on your right, which is counter-intuitive when compared to the schematic symbol. Another question is whether you've actually tested that GPU with another computer to verify that it works?

    Do you have a schematic of what you've built? Double-check the pinout of pcie and whether all the signals are routed correctly. Check whether your Reset signal is ok. Also, did you use a high speed PCB and if you did, did you calculate RF impedance of the differential pairs correctly? I think it needs 100 Ohms per pair. Anyway, if the issue was in signal integrity, I would at least expect the card to be detected, so the problem is somewhere else... Also, are both 12v and 3v correctly supplied to the card's pcie slot?

    Here's a schematic symbol and a footprint for KiCAD I've designed for my version of the adapter: https://mega.nz/#!DIxnzA6B!cvIvt-ZVpfJ3FMkgPbybyGcQviCzwBhV4VY2x-eXk5A Speaking of my ultrabay project, it's kind of stalled right now as my Y510p has been malfunctioning in a very strange way for a month or so, and I started to consider a PC build. Nevertheless, I'll still finish it at some point. P.S. I haven't yet ordered any PCBs with this footprint, so it is unknown whether it has got any mistakes.

    Lenovo Y410p/Y510p BIOS mod to enable Nvidia eGPU support

    Sure. Simply follow my normal installation guide, but replace step 3 with an MS-DOS flash preparation method described here. This method uses an old utility called HP Disk Storage Format Tool, which has been noticed not to work correctly under Windows 10. You will have to find a Windows 7 computer (earlier windows might work too!) to run it.

    This is really interesting! The Y500 mod has not received much testing at all and is only used by a couple of people at the moment. I think this is because of the adapter being initially advertised as not compatible with the y500 series. Regardless, the whitelist removal component of this mod is an exact copy of the svl7's original work for the y500, therefore it'd be a good idea to check his thread for similar issues.

    Lenovo Y410p/Y510p BIOS mod to enable Nvidia eGPU support

    First of all, you could try: 1) Reseating all the connectors (especially, the ultrabay) - this has been the main cause of this sort of problems 2) Verifying that your power supply is good (try another one) 3) Cold-booting windows (don't really remember how to do this) 4) Booting in safe mode (somehow) to see if it works 5) Does the system boot without eGPU? If not, maybe, this is related to BIOS settings? (UEFI/Legacy; AHCI/IDE; SecuceBoot, and all that stuff)

    Lenovo Y410p/Y510p BIOS mod to enable Nvidia eGPU support

    We have seen this several times before. A few people here have faced this error and despite this, their PCs continued to work fine without updating the EC firmware. This means you're probably safe to proceed without having to do anything else. If you still wish to have your EC updated, there could be a way. If I recall correctly, someone has managed to get it to flash under MS-DOS (rather than FreeDOS). You'll have to prepare an MS-DOS flash drive following the original Svl7's instructions, but keep in mind that the application required to do this doesn't work under Windows 10.

    Y510p Ultrabay Graphics card

    @Zakyn I'm not sure. Guessing that @gerald has experimentally determined that out of the two possible reset pins this one is the right one. Actually, I'm also currently designing an Ultrabay adapter. In my design I decided to go for @gerald's choice of Reset pin, but pull it up to the standby +3V (pin 64 on Lenovo schematic). There is already a pull-up on the motherboard for this pin, I've added this one just in case. Probably going to try with this pull-up unpopulated first...

    Speaking of RAM, there should be a pair of pads under the black sticker behind RAM sticks. Shorting these together with tweezers will reset CMOS too. Of course it will be no help if you managed to initiate emergency reflash and interrupted it mid-way, damaging the BIOS flash contents.

    I would strongly recommend trying different flash drive. Preferably with USB2.0, activity LED and small size like 4GB or so.

    Do you have access to another computer? Can you make sure the Yx01.bin file is in the root of the flash drive and the flash drive is formatted in FAT32? If these conditions are satisfied and you've performed the procedure described in the original post correctly, the computer should be able to pick the file up and reflash itself. Pay attention that you need to plug the drive into specific USB port. You generally need to hold the buttons for about a minute and then let it sit for about 10 minutes or so to do its thing. If your flash drive has an LED, you'll immediately see whether the computer is reading files or whether it has failed. Anyway, I'd try the @Klem's advice first. This is a more sensible thing to try in this situation.

    @jxfong2 You'll need to power the laptop with its own power brick and the eGPU with a separate desktop power supply. Also, keep in mind that RTX2070 has not been tested with this adapter, so there's a chance it won't work. @manolis Unfortunately, you can't use a regular SATA 2.5'' drive caddy for connecting to Ultrabay socket. The Ultrabay system doesn't use SATA connector inside the bay, but rather a separate high-speed PCI-e x8 socket located next to it. It is buying the plug part for this socket (cheap and in low quantities) that is a problem right now.

    Please correct me if I'm wrong, but I think these connectors are for the wrong side (this would be the same as the one on the motherboard, not the one on the ultrabay device).

    @rusTORK The ADT solutions implement PCI-E x4 by making use of the PCI-E lines available in the m.2 NVMe connectors. Although Y510p does have an m.2 port, it does not support NVMe and therefore doesn't have any PCI-E lines in there.
