G4 Wake Up Problem.

The computer wakes up, that is the fan and hard drive spin up but there is no video.

Any ideas?

I've seen something similar when my iPod is plugged in, although it's sleep in general that has a problem. It either doesn't go to sleep fully or wakes up in a weird state.

I've got a G5 with a TFT monitor doing something similar, as I've got Timbuktu on the machine in question, I think its something to do with the machine waking up and using a hertz rate the monitor doesn't support. TB2 and 'detecting' monitors brings the display back up, it's very intermittant so I haven't yet managed to get to the bottom of it...

I get it every time the Power Saver puts the machine to sleep. As it doesn't occur if the it's put to sleep from the menu that is what I'm now doing. Presumably it means that the Power Saver is somehow causing the problem?

I've finally found the answer in a thread I chanced upon. It was caused by the USB2 card I'd fitted. Doesn't make sense to me but after removing it the G4 wakes up fine - every time!

It seems not all USB cards behave the same. I can't get my own G4 DA to sleep fully, for instance -- only the hard disk and the display will sleep.

System Profiler tells me it's due to my USB card -- a 2-port Adaptec:

Attributes: Low power mode disabled because of PCI cards in slots: SLOT-4

I went through about 5 or 6 different USB cards until I found the Belkin 2 port USB 2 card works fine in my MDD G4.

The only time I get problems now is if I try sleeping the G4 with the 8000-in-one card reader plugged in.

I have the same card. If the computer falls to sleep with anything attached to the card, it is only recoverable by press and holding the power button. It seems to crash the USB, so you cant wake it up with keyboard or mouse

Cheers, I won't look into investing in a replacement CF reader then unless I switch to a firewire reader. I wasn't sure as it will sleep with the USB flash drive attached.

Mine won't. Sleep is terminal with anything attached.
