I faced with strange problem. I have debian wheezy installed on my x201, from time to time, when i try to put it into sleep, instead of that laptop just swich off. Next time when i power on and boot into linux or windows, i can't see wifi into device list. Either in lspci output or in device manager wifi card just disappeared. When in windows i pressed fn + f5 i seen only bluetooth. Hardware swich in on position, latest bios flashed.
I can see wifi card again only after power cycle.
First i thought that it is hardware problem, tried to clean pcie contacts on card with eraser, but nothing changed.
May be someone faced with same problem?
Wifi card - Centrino Advanced-N 6200
