I bought my other half a refurb MacBook (from the Apple site) in late Feb which now won't boot up (well, not all the time - occasionally does so from the hard drive, and usually does from the install disc). Apple hardware test shows nothing wrong, done the usual repair permissions, zap PRAM and re-install, but without success. No horrible noises from the hard drive. The fan sometimes comes on at full speed during the abortive boot-ups. So, I want to return it for a refund or a replacement but I can't find out who to phone. Apple's website gives phone numbers for iPhone and .mac support but no number for computer support. Past experience tells me that, in any case, they'll tell me to take it to an authorised service centre or to an Apple store, which will more than likely mean that they will repair rather than replace or refund. Because I live a fair way from either of these options, and I'm tied up with work, driving it round the country is not really all that practical - much better to stick it back in the box and send it back to Apple. So, in short: Is it a hard drive failure? (in which case I'd sooner just buy a new drive and stick it in). Alternatively, has anyone got a UK phone number I can ring to arrange to send it back to Apple? Or a UK email address?
