Tea killed my Macbook.

Repair of a liquid damage Macbook Pro

Another dead Macbook pro, deader than dead McDead from dead farm having had a mug of tea through it. Though being a 2012 15″ i7 16GB machine with the dual graphics, its still a highly desirable and worthy machine, rare as hens teeth to buy, naturally customer wanted it fixed. Identified 2 shorts to ground, rerouted those and replaced 2 resistors- still no power. Nothing, no heat from anything. A bit more investigating and it seems the Platform Controller Hub (PCH) microchip is knackerd, swapped that out and we have power. Yay! But no screen. Bums. All the video related power rails checked and present, which lead me to LP8550, which is the backlight driver chip for the screen. No backlight, no picture. Just examining this little micro chip visualy was enough. If it looks like crap, it is crap. tested with multimeter nothing coming from pin 14 – which is …. backlight power to screen. chip removed and flipped over, can clearly see where a bit of tea got under it and shorted it out ( the greenish and grey bits ). New LP8550 , flipped to show what it should look like. Chip put back onto the board, board back into the Mac and boom. Working 100% as it was the day it was new, and at a fraction of the cost from Apple 🥳 #open #righttorepair #apple #mac #macbook #liquid #water #damage #repair #nearme #horsham #sussex #upgrade #service #local #fast #logicboard #tea mycomputerworks.co.ukmacrehab.co.uk

Liquid damage repair - 2016 Macbook Pro 13" A1706 mug of tea knocked over it

macbook repair

2016 Macbook Pro 13″ A1706 mug of tea knocked over next to it spilling across the keyboard resulting in sudden death. Testing revealed No power, no charge, no green light, no screen. no keyboard. Nothing. After putting the logic board through the cleaner to remove corrosion and debris, still nothing. Suspect U7100 which is responsible for pretty much everything including main power rail G3Hot and charge sense, along with a whole bunch of other things that you’re not really interested in, are you?

U7100 removed.....

U7100 replaced...

Having replaced U7100 and a few burned caps, we have power, we have post, we have a booting machine . Still no charge, closer inspection the battery and one new battery later and we have charge sense. As seen in the photo’s First the Mac accepts 5v charge, if it’s happy and all is present it allows 9v , and again, if all is well and all is present, it boost’s to the full 20v to bring system power.

And we have no screen. I suspect that will be U8400 , the chip responsible for the LED backlight getting a boost from 12v to 50v. Now you don’t see it. Now you do ! U8400 replaced and we have a picture again, reseating and cleaning of keyboard connector and its back. Another restored to 100% working order at a fraction of what Apple charge to replace, and never repair.
