    Asus G751JY Burnt Component

    Hey guys!

    I wanted to repaste my ASUS laptop and everything went just fine, except when I tried to put it back together I accidentally inserted the battery before the screen connector. When inserting the screen I hit the connector on the board and a spark happened .

    The situation now is that the computer works (outputs over HDMI) but the screen doesnt turn on.

    I've tracked the burned component on the motherboard and found a schematic for the laptop on this forum (great stuff!). My problem now is that I can't figure out the exact name or operation of the component I burned. Please see the attached pictures. The component name in the schematics is L4506 (AC_BAT_SYS, AC_BAT_SYS_LCD). My coworker thinks it's a coil of some sort.

    Can any of you guys shed light on what the component might do, and if it would be possible to replace? My coworker says he can solder something else on there if we can find the right one.

    Thanks in advance.

    It's an 0805 ferrite bead 80 ohm 2A. Any of a similar size from a donor board will work.
