Leaked battery & corrosion: My attempt to restore this 386 motherboard!
513This SOYO 019L1 had a BIOS battery that leaked and corroded components and traces around the battery. In this video, I will restore the motherboard and remove the damage caused by the battery. I will clean the board, use white vinegar to neutralize the existing corrosion, and fix issues with the solder mask above the traces. If the board works after all this work, I will run a few benchmarks to check if the board performs as expected. This motherboard will be safe to store for many years without risking further damage.
