It looks like a dual "zero ohm resistor" pack - essentially two wire links side-by-side in a surface-mount package. It may be the cause, if either one of the links has gone open circuit or the two are shorted together. It can be replaced, but you'll need to be either very handy with a small conventional soldering iron or have a hot-air SMT rework soldering iron. Once you've desoldered it and cleaned up the board, you could simply bridge across each of the links with small pieces of thin wire.
You may well find that the system still doesn't work, though - laptop system boards are very delicate multi-layer boards which are very sensitive to electrostatic discharge and electrical faults (the same applies to desktop boards, but laptops are...
