Dead 15″ MacBook Pro A1990 repaired.

dead computer

came into us dead with no power. Apple had quoted our customer just shy of £900 to replace the logic board. With these models, the storage is soldered onto the logic board, and our customer’s data was vital. To recover the data the computer needs to be working. There are many power rails, starting at 20 volts, and going all the way down to 1.2 volts. With the logic board removed and connected to power, using a multimeter each power rail was tested for the correct voltage until we found the ‘dead’ rail which was shorted out. Voltage is then injected into the affected rail, and under the thermal imaging camera, a faulty capacitor lit up.

On removing it, the short was gone.

The capacitor was replaced and not only do we have a copy of our customer’s data made, but a fully functioning MacBook. As ever at a fraction of the price of Apple, who can not, and do not repair these devices.
