MacBook Dead after Liquid Spill - Replace Logic Board First?
I disassembled MacBook following iFixit instructions. No obviously damaged parts. There's no light when charging, nor does on/off button have any effect. This was a big spill and several parts could be damaged. Should I give up or start replacing parts, beginning with logic board? This could become expensive quickly without the ability to test individual components...
Clean and dry
it first - use electrical contact cleaner, 99% iso-alcohol and let it dry 72 hrs.(I hope you let it dry well before you attempted to power up.)
Look for scorch marks and corrosion as you clean it with a soft brush and magnifying glass. Remember to clean/dry the back of the board. Depending upon where the liquid was spilled, and what sort of liquid it was you may get/be lucky.
Remember to return and mark accepted the answer that best solves your problem.
