Hi, I bought a non-retina MacBook Pro in summer 2013 here in the UK. Recently, the battery has stopped working properly. It rarely turns on without a power source and often the date is reset to 1/1/2012 (i believe there is no longer a CMOS battery in MacBook Pros). Under EU law, goods come with a 2-year Warranty, although in the second year, the onus is on the customer to prove that the product was sold defective. http://europa.eu/youreurope/citizens/shopping/shopping-abroad/guarantees/index_en.htm According to the application "coconut battery" my laptop has had only 280 loadcycles. Surely it should be able to do more than this, hence I think it qualifies (but I could be wrong). There is, however, a complication. I replaced the hard drive myself last year with a hybrid drive (not an Apple Fusion drive) which noticeably improves performance. Will this upgrade invalidate the warranty? If Apple do acknowledge it's covered under the warranty might they just replace it with a new model with a standard configuration? I bought this model because it was relatively easy to upgrade so I could do it myself. But might Apple replace the battery for free? Thanks in advance for any suggestions.
