A7N8X Hibernate problem & BIOS flash
Hi all,
I haven't had a single problem with my A7N8X Deluxe except for this. When I hibernate in Win2k, everything goes normally until I try to switch back on... at which point nothing happens, no response at all from the computer. If I turn off the master PSU switch, and turn it back on, then I can turn on and boot up with no problems. I checked the latest BIOS and don't see any mention of this problem, so I don't want to flash unless there is a fix for this problem.. I don't know off hand what BIOS I have, is there one aside from the latest that is more stable than the others, if I were to flash it? |

Before you flash it, do you think there might be a problem with the power supply ? Even if ACPI wasn't working properly, and when you hibernated, the machine was completely shut off, the machine should still do a normal boot the next time you press the button. Maybe in fact, your +5VSB is overloaded ? +5VSB powers the green lED on the motherboard. Is the green LED lit when the machine is in its "hibernate" state ? It should be on, as long as the switch on the back of the computer is in the "ON" position and the cord is plugged in. If you've been switching the switch on the back to the "OFF" position, then that will wipe out a "sleeping" computer, but perhaps not a "hibernating" computer. Sleep is where the system state is still stored in RAM. The +5VSB powers the RAM on the motherboard while in this state. When the BIOS is awakened, it realizes the system state is in RAM, and it restores the program counter and execution carries on from where it left off. AFAIK, Hibernate stores system state on disk, and the BIOS is aware on the next boot occasion, that the system is hibernating, and the system image is pulled off disk again. I think you can completely unplug the computer in this state, and when you power back up and press the button, it should pull system state off the disk. If the computer boots and the BIOS checks and finds it is in no special ACPI state, then it will boot normally. HTH, Paul |

This may be way off base, but I had the same problem with an ABIT mobo, but same BIOS manufacturer. Try this, when you want to restart it, push and hold the power button in for a few seconds. I don't know why, but that would restart my system. arnie |

Maybe in fact, your +5VSB is overloaded ? I suppose it's possible, but I"m running a new Enermax 450 watt power supply, and I only have a TV tuner card and a Geforce 4 plugged in, plus a USB mouse, two CD drives and two hard drives. Surely that's not too much for the PSU? +5VSB powers the green lED on the motherboard. Is the green LED lit when the machine is in its "hibernate" state ? It should be on, as long as the switch on the back of the computer is in the "ON" position and the cord is plugged in. If you've been switching the switch on the back to the "OFF" position, then that will wipe out a "sleeping" computer, but perhaps not a "hibernating" computer. Nope, the LED goes out in hibernate mode. AFAIK, Hibernate stores system state on disk, and the BIOS is aware on the next boot occasion, that the system is hibernating, and the system image is pulled off disk again. I think you can completely unplug the computer in this state, and when you power back up and press the button, it should pull system state off the disk. If the computer boots and the BIOS checks and finds it is in no special ACPI state, then it will boot normally. Well I think the way that hibernate works from windows is different. When I power up after hibernating, everything looks as normal until windows starts loading, and that's when the image on the HD gets loaded. I'm pretty sure I could select Linux from my boot menu and boot up into Redhat just fine, and still restore my session next time I boot into windows. Maybe I'll take a look in the BIOS and see if there's some setting there that might affect things. It's not a big issue to have to turn off, but I'd almost like to get into the habit of hibernating all the time, because it makes booting up very fast compared with starting from scratch |

I guess the computer shuts down on hibernate, but the green LED should remain lit. I thought the green LED was powered by +5VSB, and that stays running until you switch off via the switch on the back of the computer. In any case, I have a feeling that ACPI isn't set up properly, because I believe that hibernate works the same whether the machine is just shut down or the plug is pulled. The only ACPI state I see support for in the BIOS, is via the "ACPI Suspend to RAM" [Enabled] setting. I don't know if this has any influence over hibernate or not (it would be needed for sleep). Based on your idea that Hibernate is supported by Windows and not the BIOS, maybe that is why a Hibernate setting doesn't exist in the BIOS and only the Sleep option ? If the OS has the right HAL installed (ACPI instead of "Standard PC"), then you are ready for the next step. Get a copy of dumppo.exe, and that Microsoft program has the ability to query and repair ACPI settings. The download is he ftp://ftp.microsoft.com/Products/Oem...cpi/dumppo.exe The last person I helped... http://groups.google.com/groups?hl=e....supernews.com suggested this link, for some background. While this info is for sleep, a very similar procedure should work for hibernate: http://groups.google.com/groups?hl=e...S3_standby_exe HTH, Paul |
