hi, I really don't want to have to replace my MacBook as I am not convinced it's 'died'. The power lead has light on the light at the front has light and when I turn it on I hear a two tone like it's trying to start. Then if I put my ear to the back I can hear the fan. But no chime or anything else. Once it's 'turned on' as in the fan can be heard it doesn't turn off so the Mac itself doesn't turn off. I have tried the shift, option, cmd trick any other ideas? The battery isn't removable. Thanks, Katie Edit I have had it chime once now but again went no further and still a black screen but then in turning it off after it then seemed that the screen was maybe brighter after the chime. I have checked brightness settings and have it on highest brightness screen and keyboard. The keyboard doesn't respond as in caps doesn't have a light.
