A1502 2015 Macbook Pro cider spill and repair

A1502 2015 Macbook Pro cider spill. No power, no picture. What did they do to you little Macbook, what did they do? Cider got spilled through the keyboard.Then the worst thing one can do was done. It was placed in a bag of rice and put in the airing cupboard for a few hours, taken out again, plugged in and tried to turn it on again. This caused most of the damage. U5110 area was badly shorted to ground, this area is responsible for SMC reset – SMC is the sytem contoller that when it has all nessecary and correct info and parameters will allow the Mac to turn on. In the state of this, with it shorted to ground leaves the SMC in a state of permanent reset – Which means off! Had to replace a few caps and a resistor and run a wire to U5110 as the trace and pad were wrecked.

Next up, one reason for no picture to screen is the LDVS connection (the cable that goes from graphics output to the screen) being welded to itself and blown pins.Both the LDVS connector on the boards, and the cable from the screen had to be replaced.

Next, we have a very feignt picture now to screen, if we hold a bright light and shine it through the back of the screen through the plastic Apple logo, we can see the feignt flashing image of a folder with a question mark on the screen. Why this folder with question mark? Thats the Mac/ board fired up and booted sayingit cant find the hard drive or SSD to boot from, as we always remove the SSD/ HDD when working on these things to prevend any accidental damage to customer data.- So, the feignt image tells us there is no back light power to screen. The chip that controls this is U7700 – which essentialy take a 12 volt line and whacks it upto 50 volts, that’s what effectivley turns the screen on.

So U7700 replaced along with an iffy looking resistor, and we now have full image to our test screen. Our work is done, keyboard cleaned up, Mac put back together again, and we have one fully functioning Macbook Pro at a fraction of the cost of Apple. 🙌💪✊

Dead 1TB SSD data recovery

failed SSD data recovery

1TB SSD (Solid state drive) came into us this morning, dead. Like dead dead dead. The machine it came from had been running quite hot. Upon plugging it into any other machine it prevents the machine from booting, and if plugged in via USB caddy to try and see if there’s any data also freezes the machine. A very dead SSD. So we removed it from its housing – Inspected the logic board for any obvious bad areas ( blown resistor or capacitor etc ) , saw nothing, tested with multi meter that circuitry was OK, upon inspecting the two large chips – that’s the actual memory where your data is written to, the solder balls around it looked grey and mushy, as would most very certainly be under neath too. These chips are soldered to the board by an array of sometimes hundreds of solder balls. Knowing it had come from a hot environment we knew it was likley bad solder under thses chips. So, using the correct temperature and pressure reflowed the solder. Look at the before and after pictures, grey solder blobs vs nice shiney solder balls. Cleaned up and plugged into a USB caddy, plugged into our recovery rig and the drive showed up and preseted itself with a corrupt partition table, using specialist tools & software this data is now being recovered to a new drive. 👌 #data #recovery #SSD #professional #open #righttorepair #apple #mac #macbook #dead #liquid #water #damage #repair #nearme #horsham #sussex #upgrade #vintage #service #local #fast #logicboard #fix #screen #replacement #lost #password #EFI #lock #imac #dead #hard #drive https://www.mycomputerworks.co.uk/ https://macrehab.co.uk/

Recovering the data post repair to a new drive – Although this SSD has ben repaired, it is always best practice to use a new SSD as it’s likley to go bad again. Reflowing is only a temporary fix for this sort of thing, it may last a week, or months. But it will fail again.
