- First for a long time was a white screen and noisy cooler
- After the system battery icon was crossed out and the indicator on the left side of macbook does not show anything and everything worked cooler at high speed (he was cold macbook)
- After reboot appeared and the system has stopped running
Few days ago I have installed Mac Os X 10.6.4 but when the system had started working I saw my desktop it was at least 2-3 sec, after that macbook went to sleep mode. I pressed any key macbook and system started working, but without lighting screen. I used bright lamp and saw that all shortcuts and indicators (like wifi, battery etc.) have appeared on my desktop. After 2-3 sec macbook went to sleep mode again. Pressing on buttons and light from lamp gave me possibility to done update to 10.6.5 and after to 10.6.8. But at the end situation was not changed.
When I boot macbook with using install DVD, I can use all utilities (disk utility, network util etc.) and macbook don't goes to sleep mode and screen has light. In my opinion reason of this - not correct installation latest EFI or SMC updates. I tried to install EFI update 2.0 and SMC 1.5 for 10.6.5/10.6.8, but system showed me that I can't do this update. I'll try to find some way to make EFI update, maybe this would help me solve this problem. P.S. answer from Applle support: Our updates can't to break your macbook... it's just coincidence. Probability theory it's just mystification
this is info about my MacBook Pro 13" (mid 2010) MC374ll/A. As you can see I have SMC version 1.68f99 instead 1.62f7

If somebody has same problem, welcome to discussion. Maybe we'll find way to solve this problem... Or Apple will make fixes for us.
