Hi,
I just tried the live CD for CentOS 5.0 on a desktop computer and decided to see if suspend worked. It seems it did, but I'm unable to start the machine again.
It's a DIY system with an Asus K8V-X motherboard[1], an AMD Clawhammer 3200+ and 1 GB of Kingston ECC RAM. The system has been perfectly stable despite being utterly abused on a daily basis for almost 3 years.
I've tried: - unplug power cord - reset CMOS - remove BIOS battery - remove all RAM
When resetting the CMOS, the CPU FAN and hard drives power up, which it has never done before (IIRC). This is the only way I can get anything to power on, there's no reaction whatsoever when I hit the power or reset buttons.
Please don't tell me that clicking a button in a GUI menu has broken my favourite testing PC permanently. Any hints would be very appreciated.

Err, wrong link. Here's the right one: http://www.asus.com.tw/products.aspx?l1=3&l2=14&l3=67&l4=0&m...
I have one idea that may work. Try seeing if your bios supports a bios upgrade floppy (it would say so in the owners manual). Now by bios upgrade floppy I don't mean the usual type that use an os. There are some that the bios will directly read from without an os being used. The concept is to recover from failed bios upgrades. The reason I suggest this is because I think the setting that's keeping your system off is hiding in your bios' acpi table and I don't think a bios reset will dump it, but a bios upgrade might.

My motherboard do support such BIOS upgrades (really nice since it's OS independent) but you need to get to the POST before you can ask it to search for the floppy.
But it won't power on at all. The CPU FAN doesn't start, the disk doesn't rotate, the monitor doesn't get any signal. The only thing that indicates the slightest sign of life is the LED on the motherboard and my keyboard if I press Num Lock.
Is there something on the motherboard I can disconnect to reset the ACPI table?

Seems to me there is room to suspect a hardware issue instead of acpi. I would confirm power supply connector to mainboard by removing and reinserting until properly seated. Also would confirm two wires from power button on case/chassis are correctly connected to proper pin terminals at edge of mainboard. If still no joy, would swap a known good power supply. If that fails, you might try removing the power switch leads from the pin terminal strip and use a phillips screwdriver blade or other appropriate tool to short the proper pins momentarily to start the beast. I have replaced three bad power switches in the recent few years, so they do fail.

In its current configuration, this system has survived over 500 boots. It has failed this one time, which is the only time I've tried to use suspend. I've tested every component in other PC's and they all seem to function properly, except the motherboard.
My theory is that the suspend succeeded but perhaps the BIOS settings don't define any way to switch state SLEEP -> ON. The system has been without power and BIOS battery over night, but it hasn't changed anything.
Do anybody know of a way to force wake up?

Many main boards have a place to set a jumper to reset the BIOS to the default state. I've never tried resetting things using this (and try not to deal with hardware if I can help it which is my my company name is not Celestial Hardware :-).

I have never had an OS make a machine where a hard reset wouldn't reboot it. Are you sure that some hardware didn't fail at the same time? Maybe the power supply.

Remove the motherboard battery for an hour or two or short the CMOS jumper and see if it wakes up. Otherwise, something is definitely broken. Maybe an unsupported suspend state fried something weak in the motherboard.
I got problems with some DELL Poweregde server long time ago. Running hwclock command was crashing the server and sometime, this happened 2 times the server was not rebooting anymore, we had to replace the motherboard. Maybe some critical NVRAM region were corrupted by the suspend.
Try to contact your hardware support :-)

I would try removing all cards from the PCI slots, disconnect the IDE cables and any other I/O than might be connected and try it that way. Obviously, it won't go very far w/o a keyboard and you won't be able to see much w/o a video card but it SHOULD stay powered on. An old PCI video card might be nice to try, in the event that power will stay on with all I/O pulled. Also, you might try using different memory -- or try the original memory in another box. Also, if you've been inside the box already, it might be worthwhile to turn that baby upside down and shake and/or jar it, just in case you dropped a screw or washer somewhere inside.

I have seen it where the cpu has died can not remember if the fan was still working but it worth a check since you said it is a 3 year old PC

Try to power on the computer when the power cord is disconnected to discharge everything. Or be patient, sometime the problem disappear after 1 days.

There's a LED on the motherboard which should indicate whether it's discharged, and it turns off after 3-5 secs whenever I unplug the power cord. I've let the system stay unplugged for 3 hours with the same result. I tried your advice but it didn't help. Thanks anyway.
