These cheap POST80 displays do not use PCI-e signalling. Looking at<br>
Wistron Dasher-2 schematics that to my knowledge is (a/the) x230<br>
mainboard, required LPC signals are not routed to either of the<br>
mini-PCI-e slots. There is a separate (unpopulated) connector CN14 and<br>
card-edge GF1 to use for post80 display.<br>

I have one these as well. That mini-PCI-e card-edge is not so great,<br>
it is missing pads for pins 1 and 2. It also appears to be narrower<br>
what the specs says, so you need to be very careful with proper<br>
alignment on installation. Also have laptop battery removed while<br>
doing so!<br>

I would measure the 3.3V power rail on the mainboard (VCC3WLAN) . If<br>
you had installed the postcard improperly/skewed to the socket you<br>
could have caused some shortcut to GND and damaged the on-board power<br>
circuitry. Other than that, I don't see how this post card could harm<br>
a x230.<br>
<br>
Hope this helps,<br>
