I was wondering why you would want to put the computer to sleep overnight?
just that it starts up quicker. That's all. I NEVER had any sleep issues with any of my macs before so I thought nothing of it.Why not just shut it down and then in the morning switch it back on? Are there benefits to putting it to sleep apart from a quicker switch on time. I have a Mac Pro 2.8 with 8800GT on order and I am now concerned about this issue

I put this post up on the main board. Just wondering if anybody has tried it earlier, and what results?
Decided to call Apple myself about this issue.
He said to reset Power Management by:
Go to Mac HD/lib/pref/System Configuration folder/then trash com.apple.PowerManagement.
Has anyone tried this yet? I did and it seems to be working, but no long sleeps yet. -

It makes a lot of sense to shut down at night. Boot vs wake from sleep is only about 15 seconds longer for me ... yet my Mac Pro system consumes 36 watts of power in sleep mode (measured via UPS power draw meter), including the few watts drawn by the power brick for my monitor. 36 watts is a lot when multiplied by 10 to 16 hours and then by millions of computers! Like the equivalent of a power plant.
No additional wear and tear on components: the hard disks are shut down during sleep anyway and whether memory and network adapters have power or not does not affect their longevity.
Cheers,

Feb 25, 2008 1:43 PMby Emery Martin1,It's the 2600XT, that's the problem. Just talked to Applecare today after my replacement for my 4 time repair machine was replaced with the stock Mac Pro and was exhibiting the sleep and artifacting problems. They said it was a known issue that the stock 2600XT card was indeed causing problems. -
Feb 25, 2008 1:50 PMby yvonnejim,Yes, but what about all of us ( me ) with the 8800 card, and the same problem?Emery Martin1 wrote:

Okay, so what do we DO about it? Wait, I guess. -
Feb 25, 2008 1:51 PMby dosers,Really?
New piece of the puzzle if what they said was correct.
I assume you mean the Kernel panic though - it certainly is not related to the sleep / reboot issue as system with the 8800 Card (and in fact, even the elusive Quadro) are having the sleep issues just the same...
