Ooooh. Harsh.
My lad had a recent macbook fault, in as much as it would not start up. Of course, nothing backed up
He took it to Apple, Norwich and they diagnosed liquid damage. My lad says impossible. Only he uses it, and I believe him. They recommended data recovery, and gave the name of a company that they recommend. Got in contact with them for a quote, on-line £300 + VAT. They were on the phone to me in < 1 minute.
I suggested a 2nd opinion. He's a student with 'no' money (except when it comes to music producing software, going out, new clothes etc, etc.)
Got an appointment at Apple, Cambridge. As yes they said, common fault with this model, something about a bracket on the pcb holding the hard drive (?).
Left it with them for 3 hours. Went back, fixed, cleaned, no mention of liquid damage. How much......£0......and the laptop is 4 years old!
He could not believe his luck.
