Restarting from sleep mode.....
Hi all,
I have just started using the sleep mode on my iMac 20" Core Duo. I think that it is a wonderful idea but I have a small problem......

When I bring the mac out of sleep the system comes back to life great but for some reason my 250Gb External USB 2.0 HDD does not always restart at the same time. The little icon is on the desktop still but the HDD itself does not come to life. The only way that I have found to restart the External HDD is to restart the iMac. Which kind of defeats the idea of putting it in sleep mode to start with anyway.

This is however an intermittent problem. Sometimes it works and sometimes it don't.

Any suggestions appreciated.

I'm sorry I have no answer for you, but in fact, have another question. When sleeping, is anything happening at all (I suspect not). For example: mail checks. I'm assuming everything just spins down, and powers down into standby mode, which doesn't really work for me, but I'm not 100% sure.

I have my iMac in my room and while I am laid in bed I can't hear the drive moving so I guess it does.

Oh and does anyone have any ideas as to how to solve my problem??

You could try resetting the PMU. Unfortunatly it is inside the Mac. Most likely you are covered under warranty. I'd take it to an AASP. PMU controls the start, stop, sleep and wake functions in a Mac.

Edit: Incorrectly resseting the PMU is potentially damaging to the system.

Looks like the connection is interupted by putting the computer to sleep...
