How can I check?

If the two plated holes at the top left and top
right corner are the power connections, then
probably yes. I screwed the 2 screws back
into their places through these holes after
putting the card in place.

Maybe the device is just broken.

Also, it seems to be a clone of the genuine
intel device. It doesn't look exactly like
in the above link (instead of the top three
chips I have one silver box, but perhaps
the Intel pic shows the card with this casing

The technical specification from the Intel page
mentions an LED. I don't see any LED fire up
when the laptop boots or is on. Perhaps this
is an evidence for the card being broken.

If I plug the old (the one installed in the
laptop when I bought it, 2007) Broadcom device
instead, it gets detected:

none1 at pci0:48:0:0:      class=0x028000 card=0x1371103c chip=0x431214e4 rev=0x02 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'BCM4310 UART (Wireless Ethernet Adapter)'
    class      = network

(I haven't checked bwi(4) yet, but will do
if the Intel card comes to nothing).

So to conclude, I'll have to assume that the
Intel card is dead, so it seems..

many thanks for your help
