Severed a gray wire to the X41T LCD...what's it for?

[Fox5]

So for the longest time, I've had a very wobbly screen on my X41T, to the point where the tablet functionality was useless and I couldn't use the laptop in a moving vehicle. A year ago I sent it to some 3rd party (thinkpad authorized) repair place which told me they could repair it easily and cheaply. When they got it, they told me repair fees would be $1800 (the cost of a new x41t) and that they could return it to me for $50.

Got fed up with the wobbly screen, and thinking that the new netbooks and looking pretty nice and coming close to the specs of the x41t (sans tablet functionality), didn't really mind the chance that I could kill my X41T. Well, it was rather simple to disassemble, and after taking the laptop apart, a single screw governed the wobblyness. I tightened all the way, and the laptop looks nearly brand new again and is rock solid.

Thing is, at some point while I was taking it apart, a gray wire that goes to the LCD disconnected (or maybe it always was). There are two thick cable bundles (I'm assuming LCD screen + tablet functionality + bezel buttons), a white and black cable (power), and a gray cable. The gray cable is not a normal wire, inside the insulation is a clear plastic wire. I'm guessing it's either a fake cable made to snap easily so IBM can tell if the laptop was disassembled, or it's a fiber optic cable connecting to who knows what. All functionality of tablet seems to be in tact.

Perhaps its a diagnostics cable used in the factory, or maybe it hooked up the fingerprint reader. I wouldn't know, I never used it anyway, and I'm running Ubuntu which I don't think has support for it.

At this point, fixing my tablet hinged has quelled my desire for a netbook though. Bigger screen, more power, and similar weight, and a 32GB compactflash drive that gives decent enough performance with writeback enabled. Only complaint is the poor battery life.

Anyhow, I was just curious if anyone knew what the gray wire actually did.

black and white are 802.11 wifi antenna
gray is bluetooth antenna

Well that's a shame. I never used the bluetooth much, but it wasn't completely unused like the fingerprint scanner. Oh well, maybe it'll still get some reception anyway.

(message deleted) nevermind, for some reason I thought you had an X61t, not an X41t...
