Hey, Briefly outline the problem: One day I was working with my MB (version 2009) when sudden my spacebar and backspace no longer worked. Thought it was a software problem because I was surfing the web, I have not paid close attention to that but a bit later, the arrow keys failed also. Anyway still not a disaster, I restart later. But my battery was almost flat so my MB fell out. I then plugged it into the socket and when I got it to start the gray startup screen typical for Lion. But I saw that the "breathing" light suddenly went out on the front, and not much later, my laptop. Restart and the same situation ... Then I discovered that if I stayed tapping any key that the system fully booted. Once arrived on the desktop, my laptop always gived me the following warning "are you sure you want to shut your computer, standby, cancel ,..." A warning that I had never seen it, I suppose this is a warning when your battery is flat, that you get to see, but it was plugged into the power so it could not. When I did nothing with the MB it felled out. When I wanted to start him he no longer responded. Just black screen ... Battery indicator lights indicated that he was charged, what was true but otherwise no life. With this story I am drawn to the Apple store and they went to investigate. Now yesterday I got the solution they proposed. € 425 (incl VAT). The repairs they suggested I find a bit on the strange, so my question is, can the proposed repairs be the cause that my MB will not boot? Below is the full specification of the bill: Hours: 2 X 80 = 160euro (ex vat) Housing, Top Case, with Keyboard, backlit, Flemish 191.63 euros (ex VAT) So it was with the housing, top case, ... according to them. Monday I will have to pass by because the repairmen don't work in the weekends ... They will tell me more. But what do you think? It's a premium reseller, not a real apple store.
