Three T400 covers?

[whizkid]

My T400 fell off a chair. A screw mount on the screen cover (the laptop's lid) broke, and the cover separates from the screen when I close it. I got out my handy dandy HMM and found three different screen covers. Only two apply to me, as I have an LED backlight.

I know I can find the exact match from a part seller, but they are pricy. eBay has better prices, but sellers are less than enthusiastic about opening their screens just to find the part number.

So, just how different are these screens? Do I have to worry about which one I get, or will any do?

Thanks,
Chris

I assume the difference is due to the connection to the LED sub card. I have only seen one configuration, but I have seen pictures of an arrangement where the LED sub card has a separate connection to the panel - not the 2-wire cord like the one from an inverter, but a small ribbon. I assume this is related to the high-nit option. All I can say is that almost all the lids have the same configuration.

Thanks, Rich.

As it happens, I have a high-nit LED screen, so now I'm leery again. I don't feel bad about cutting a new slot, but I'd like to avoid having extra ones. I'll probably just buy one and see what happens.
