I have a white Macbook 2008 model 2.2 Ghz Core 2 Duo 1gb 667 DDR2 SDRAM. Its been updated to Leopard. For last few days when I start it up for the first time it would make the screen go blank and the white led used to blink. I then did an SMC reset as described in the Mac support website. The problem got solved. But now I have to do an SMC reset every morning. Wonder if there is a permanent fix?
