I know, it's a well discussed topic, but it always ends with "Hey, we're AMD, not Intel". I think that's no reason to capitulate, so let's start collecting information about sleep on AMD. I think it's not only up to the processor, but to the mobo - so let's collect information about your success or non-succes with sleep on your AMD-System. Please post your specs, too, so we can compare and draw a conclusion. I'll start.

<b>My success with sleep on my AMD with the SleepKernel looks like this:</b>
- changing ACPI-Mode in BIOS to "S1" and changing ACPI-Mode in system, too, let my sleep work - but only a "half-sleep". Hard drives are shut down, but the fans still are turned on, so no really success.
- changing ACPI-Mode in BIOS to "S3" and changing ACPI-Mode in system, too, brings my system to the deep-sleep. No noise, but wake up doesn't work. Just a black screen and a running system.
- changing ACPI-Mode in BIOS to "S1 and S3" and changing ACPI-Mode between "S0, S1, S3, S5 and S7" doesn't work, too. System gets into "half-sleep" and can't be woken up.

<b>My system specs:</b>
AMD Athlon 64 3200+ Venice (SSE3)
NVidia GeForce 6600GT PCI-E (working with NVInject, dual screen working with DVI-VGA converter)
EPOX 9HEAI Rev 3 Mainboard with VIA K8T890 and VT8237R chipset
<i> I think the rest doesn't care to this topic</i>

<b>My experiments worked like this:</b>
- changing the kernel from default Zeph-Kernel to SleepKernel (by using Kalyway kernel installer - see attachment)
- changing BIOS ACPI-Mode
- changing system's ACPI-Mode by typing following commands in Terminal:

<i>Check current ACPI-Mode</i>
<font color="#333333">pmset -g | grep hibernatemode</font>

<i>Change ACPI-Mode</i>
<font color="#333333">sudo pmset -a hibernatemode X</font>

X is the number of the ACPI-Mode. Here a <b>list of the available modes</b>:

# 0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
# 1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
# 3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
# 5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
# 7 - This is the same as mode 3, but it’s for those using secure virtual memory.

That's all for <i>my</i> sleep-success with OSx86/AMD. Please attend at this topic, I think it could be useful for the evolution of OSx86 on AMD-Processors.

Attached is the Kalyway Kernel Installer with all available kernels. If you want to try sleep at your system, the first step is to install the SleepKernel.

Sleep is working here

I'm using the sleep kernel and mode 0, not sure which mode is should use btw?

But mode 0 seems to work, will try others too

This is my setup

AMD Athlon 64 X2 5000+ (SSE3)
NVidia 8600GT PCI-E, using EFI string
MCP61 Chipset

Just let me know if you need to know anything else

Edit:

Mode 1 works also, do i need to reboot whenever i change the mode?

So you're system is completely quiet in sleep-mode?

Yes it is, i only got a blinking power light.

Wooh, that's what I call "success" ;-)
Can you post further specs of your system please?

Yeah, this looks like a success, we could be having a winner here! =) Go p-J!

=)

I am running S1 with option # 3 and it seems to be working quite well now. Everything is still functional when it wakes up. Sweet!

Thanks StealthMode and p-J for your reports, but can you please post your system's specs?

WinLinMac, what about your system, does sleep work? ;-)

Sorry for the later response but i was sleeping Different timezone and all ;p
Here are my specs:

I haven't tried yet, I've disabled it. I'll try it and let you know in this thread.
