Re: W520 second half mini-pcie slot

Are there really 3 internal pcie slots? From the hardware maintenance manual it doesn't look like there is a slot under the palm rest. It only mentions the two slots under the keyboard.

Re: W520 second half mini-pcie slot

Bump. It seems like an official Lenovo support specialst suggest on this thread that there are indeed 3 internal PCIe slots. I'm would love to have an additional slot since the two under the keyboard are already filled up with the WiFi card and an Intel SSD. After reading the Hardware Maintenance Manual I'm skeptical as to the existence of a third slot. Could anyone who has actually seen this slot please confirm?

There are only two mini-PCIe slots in the W520. There are other cards (MDC, BDC, I/O sub) installed, but these are not mini-PCIe form factors.

Re: W520 second half mini-pcie slot

Thanks for the (disappointing) answer harrisb. I checked and the OP ist right, the PDF specs from Lenovo say 1 full 2 half. I guess they mean that the W520 is able to take 1 full at most and 2 half at most by using the full slot for a half-sized card.
