Sigh. There is no such thing as an "M.2 slot". There is always a key and a size. The T480 has three M.2 slots:
1. Optional M.2 key M 2280 in the main bay via an adapter.
2. M.2 key B 2242, the Lite On T11 works there for an SSD. It's the only consumer M>2 key B+M 2242 PCIe SSD. This generation doesn't support SATA disks in this slot, the T470 did.
3. M.2 key E 2230 as practically all laptops do since Broadwell for wifi.
- dTal 8y agoBugger. So the FPGA card won't work then. Thanks for explaining. It's all very confusing and frustrating. So the chances of me finding anything useful to put in that slot are roughly nil, then? I can see no physical or technical reason why my slot should not support this card, except that the card only supports two out of the three possible PCIe-carrying configurations, and I was unlucky. Seems like a poorly designed "standard".
- chx 8y agoOf course it will work! That's the point: remove the wifi card and use a USB dongle instead. Practically every laptop featuring a Broadwell or later CPU will work.
- dTal 8y agoI meant in my spare, useless 'key B' slot, which will still be spare and useless if I take the wifi card out. It especially rankles because they devoted two whole PCIe lanes to that damn slot, which would be better put to use unbottlenecking my highly expensive Samsung P981 NVMe drive. The T480s does not suffer this problem.
- chx 8y agoThe T480 is almost a T470 and unbottlenecking said drive would've required a motherboard redesign and a new adapter into the bay. Not this generation. The T470 was a completely new design, chassis and planar both. The T480s is a new machine.
