Chosen Solution

While repairing the broken power jack on my laptop, I managed to snap the corner of the motherboard off and I would like to know if this is salvageable or not. It is roughly a 1x1cm piece that goes above the power jack and Ethernet port because the laptop is worth nothing to sell and currently there’s a lot of financial stress at home an we aren’t in a position to afford even a used £100 laptop and selling for parts will take a long time

There’s not much you can break there without fatally damaging the motherboard. You can lose. small corner, but losing much more will ruin the board. We need photos of the actual board to judge if it’s repairable or a total loss. Boards aren’t cheap in the US; $50-70 from a quick eBay search.
