Hey gals and guys...
I got a defective X250 which shows no image on the display, when removing the bottom cover the first thing I noticed was this chip, its cover is glued to the black tape:
Does anybody knows what's the function of the chip? Is it bad it it stay "open"? Should I be worried or should I just tape it?
Thanks a lot in advance for your help and have a good start of the weekend!

Re: Question to X250 Motherboard
That's a pulse transformer, probably the NA69.
It's a bunch of chokes to regulate the data lines of the LAN port nearby.
It's recommended to keep it closed.
