Check what kind of hardware slots are available linux

command-line hardware

13,794

I think this will do it:

sudo dmidecode --type connector

For me, it shows a lot of ports - masses of USBs, a Firewire, ESATA and SATA connectors etc. I expect it will show an m.2 port - although it might have a different name - for example, my Firewire shows up as P1394.

If you're interested, here is the output for me, and here is the output for just sudo dmidecode.

My laptop comes in different models, some of them have an m.2 sdd slot. The retailer I bought it from doesn't provide information in great detail and I'd like to know without opening up the laptop if I have m.2 available.

Is there a command I can run to check that? Like lspci for example?

  Can you provide the exact model of your laptop? (From the sticker underneath or wherever it is?)

  Maybe the output of sudo lshw -businfo can give a hint?

Can't speak for the OP, but in my case the output does not list anything at all.

I only get the first three lines talking about versions and SMBIOS, nothing useful. No idea why.

It worked for me on a 64 bit 14.04 desktop system. Asus hardware.

That only returned a list of USB, network, and mini-jack connectors.. I think if would have been there it should have listed PCI interfaces at least as well?

@simernes try the second command - sudo dmidecode

I did that both with --type and without, that's what I meant in my comment.

@simernes that's really strange, let me do a bit of searching.

Mine shows the slots but doesn't display whether or not they are being used.

@MatthewPiziak I’m not sure mine shoes which are being used, but this was 2 years ago so my memory is poor! I don’t have Ubuntu on hand to test... lsusb will show you USBs that are plugged in... I’m not sure there’s a way to see ports and what’s connected.
