New Leopard Bug - Sleep Mode
I want you to know first that Apple have really impressed me this year. Tiger has been the most robust implementation of Unix that I may have worked with in my entire career. This is what makes Leopard so much more disappointing.
Over the past year I have used sleep mode with good effect. When I have to move I simply shut the screen and relocate - sometimes leaving my Mac Book Pro in standby, on battery, in my bag, for many hours, confident that I would have a reasonable charge left when I reopened. Weeks have gone by without a need to reboot. This is very impressive.
But woe Leopard. Shut your laptop and it seems to crash while in sleep mode. Restart it by holding down the power key and after the Apple boot the screen goes black and there is high disk activity. I discovered that the black screen is simply that Leopard has dimmed the brightness right down to make the screen black. So Leopard may not actually has crashed after all. The white standby light doesn't appear to work either. Next time this happens to me I'll try just turning up the brightness and let you know.
I have the same trouble with Leopard.
Sleep mode appears to crash it.

Installed Leopard screen goes black in sleep mode, need to reboot. Had logic board replaced, did not help. Back to Apple 4 times. They are checking it again. I switched from PC, this is frustrating.

Has anyone found a solution to this problem? I'm still getting it on OS X v10.5.2. Has Apple acknowledged the problem?

I had the same problem :( After sleep, screen is black. Everything else works (ipod syncs, hdd works, etc) just the screen is black. I can't add more light manually by f2. I can't switch to external screen and black. Ctrl+Option+Eject twice doesn't helps. Only hard reset (power button for 4 seconds) helps. But it's very annoying. I'm waiting for a proper update / bugfix.. :( And this is my first Apple experience... I like the whole system but this is very lame & nasty.
