M2N-MX power management under XP
I've got a machine with an M2N-MX mobo. This thing doesn't seem to allow
power management under XP! Even basic things like Standby and Hibernate are missing. When you press the "Turn Off Computer" button, the only options are Restart and Turn Off; Standby is greyed out, and Hibernate isn't even presented as an option in Power Management properties. I've flashed it to the latest available AMI-BIOS (0704). I've set the ACPI support from ACPI 1.0 to 2.0 to 3.0 and back down, nothing has fixed the issue. I've also got it running under Ubuntu 7.04 64-bit, and it's the same issues there. Under it, the temperature sensor utilities tell me "no sensors found". But interestingly the AMD Cool'n'Quiet continues to work, I see the two processor cores (Athlon X2 4600+) changing speeds up and down independently like normal. I have another system with an Asus mobo, M2NPV-VM, with the same basic chipset (Nforce 430), but with a Phoenix BIOS which is working perfectly. Any ideas? Yousuf Khan |

Yousuf Khan If you go to Device Manager, and check the properties of "Computer", does it say "Standard PC" or "ACPI Multiprocesssor PC" ? If the HAL is "Standard PC", that would explain the limited options to turn off the computer. If you did a clean install, did you get an error message, about some problem with ACPI ? Like "not compliant" ? I had that happen with one Asus BIOS, where when I tried to install, the ACPI tables from the BIOS, were not to the OS installer's liking. I ended up with a "Standard PC" as a result, and had to endure that "it is safe to turn off your PC" crap. Once I tried a later version of the BIOS, then I could install an ACPI HAL, as normal. Some HAL changes are easy. Changing from one flavor of ACPI HAL to another, is a "driver change". But I suspect that escaping from "Standard PC" is not going to be so easy. http://support.microsoft.com/kb/237556/en-us During an OS install, you can press F5 to force a HAL. Normally I think it would select an ACPI HAL without any coaching, if the ingredients are there. http://support.microsoft.com/kb/299340/en-us Also, when using Ubuntu, did you examine the log messages that occur during boot ? Were there any complaints about the ACPI tables passed by the BIOS ? You might get more useful info from Linux, than from Windows, if there is a problem. There are also a couple of reports here, of weirdness with that motherboard. One guy could not get both cores to be recognized when using a dual core processor. (Make sure you report your problem to Asus tech support, so maybe in three months time, you'll see a new BIOS release with a fix. Asus is probably not monitoring these forums, looking for trouble.) http://vip.asus.com/forum/topic.aspx...ge=1&count=100 Paul |

I ended up with a "Standard PC" as a result, and had to endure that "it is safe to turn off your PC" crap. Yeah, it was a clean install, no problems, which is what's surprising me about this problem. The only problem I see in the hardware is a little yellow exclamation point on some USB composite device, but everything else is working fine, including all USB devices. Speaking of turning off your PC, when I do choose "Turn off PC", it doesn't turn off, it reboots. I have to quickly press the power button before it boots to an OS again. Also, when using Ubuntu, did you examine the log messages that occur during boot ? Were there any complaints about the ACPI tables passed by the BIOS ? You might get more useful info from Linux, than from Windows, if there is a problem. No, I didn't check the messages in Ubuntu yet, but I did check the Windows logs, and there were no alerts of any kind in there. I don't know if I have to set some error-check level in Windows to see any messages of this type though. Throwing something else out from out of left-field. Earlier during the installation process for this machine I was experimenting with trying to get the Xen virtualization hypervisor going with Ubuntu. I couldn't get it going, so I reinstalled Ubuntu from scratch without any of the Xen stuff in there. I'm wondering if maybe some kind of Xen stub is left behind that gets loaded automatically -- and invisibly -- with Grub? This might explain the reduction of features in the PC: they're being virtualized away. It's a very slim chance, I'll admit.

Can you test with a spare disk and just install Windows on it ? Just to see if sanity is at all possible. Paul |

Well, I did get through to Asus tech support finally. Told their tech support guy the symptoms under Windows XP. I also then made the fatal mistake of mentioning that I had Linux installed on the box. Well, it is usually a fatal mistake because tech support is usually looking for any excuse to pass off the blame on anything that they can. I told him that the same problems were occurring under Ubuntu Linux, and to my astonishment, this technician actually said that that proved to him that there was a problem with the motherboard! He told me to get in touch with their RMA department. Anyways, the techsup guy thinks that perhaps the sensor chips on the board are defective. Yousuf Khan |

Yousuf Khan It'll be interesting to see if an RMA can fix it. Usually on those boards, the hardware monitor is part of the SuperI/O chip. If the SuperI/O was bad, you'd think there would be other symptoms, such as defective floppy, serial port, parallel port etc. It would be a bit strange for only the sensor section to be bad. Paul |

The thing is, it's possible that all of those things are bad too, but it also happens to be a whole bunch of the things that we're *not* using. No floppy drive attached on the system, no need for serial port, printer services is obtained through USB or network, etc. Super I/O is old legacy stuff these days. Yousuf Khan |

Paul It didn't fix a thing. According to the worksheet, they replaced the board with a new board, but the exact same issues are cropping up again. I don't know if I want to bother with RMA'ing it again. Yousuf Khan |

I took a look at the BIOS info on the Asus download site for M2N-MX, but the change log doesn't mention anything close to your symptoms. Other than changing BIOS versions, I would go back to software testing. On shutdown, is it still automatically restarting again ? Sometimes that is related to the Magic Packet wakeup feature of a network interface, as some network interfaces basically wake up when any packet is received. Disconnecting the network cable, then testing shutdown, may show a difference in behavior, if that is the case. Paul |
