I have a Macbook pro I bought used 6 months ago. It would about 3 years old running OSX 10.6.4 with 4g ram and a fresh battery. Now my problem is all of a sudden every time I close the lid (or use the menu) to sleep it totally locks up. The sleep light stays lit the whole time (no pulsing) when I open the lid to wake it the light dims a bit but the screen stays black. End up having to hard boot it! And then it takes 5 minutes to boot ontop of it all. When booting it gets to a blueish gray screen and hangs there for 3 or 4 mins. Any ideas?
