Liquid damage, battery charging as normal but won't switch on.


My macbook pro got hit by the 'toddler with the orange juice' which seems to be a regular problem but the results are different to the previous threads I've seen. I turned upside down and dried out for a few weeks.

The charger mag strip orange/green light and charge lights are working as normal - suggesting battery is too, but no response from the on button.

I've tried the shift/ctrl/cmd + power and holding down for 10 secs without mains connected and then with. nada.

Could this need just cleaning or something else I could do myself without any previous experience? I'm skint and apple are expensive.

Thank you!

Orange juice is acidic... cleaning is called for (hope it's not too late). You could try by passing the topcase on button using the power jumper pads (but force starting a questionable logic board could cause further damage)

After disassembly following the guide and using the proper tools look for damage to the logic board. If you're lucky the juice stayed in the top case/keyboard, if it didn't corroded etched parts would have to be cleaned and/or replaced.

Good luck,

Thank you - very useful link...I just hope I'm in time


A few weeks after the spill the board may begin to be corroded at specific places. Clean these spots with 90% isopropyl alcohol using the thootbrush before washing the board as specified in my post.
