"Micron" computer sleeps, won't awake

[silverback]

We have a Micron desktop computer running W2K Pro. After booting normally, it went into "Sleep" mode, and we've so far not been able to revive it. The "Sleep" button on the keyboard isn't effective, and there is no reboot/restart button on the case. The On/Off button has no effect. We've unplugged the computer for up to 30 minutes, and it immediately reverts to its "sleep" mode. I need help badly--the computer's owner is getting grouchy!

It sounds like you have the "new" style on\off switch, where just clicking the button has no effect, as that just sends a command to Windows. To truely turn off the computer, hold down the button for a few seconds.

Windows is infamous for a bad sleeping ability, so you will likely want to turn that feature off.

That's not quite the problem, Henry. The problem is that we can't get it OUT of sleep mode. We've done a little more checking--got a pin-out diagram of the ATX power supply. Shorting pin 14 (Power Supply ON) to ground SHOULD have caused the box to power supply to come on, but it did not. So, we apparently have a bad power supply.

This problem had originally presented with the computer going into sleep mode unless you selected "Boot with logging" while W2K started. Always in the past, the computer's user had recovered from this by unplugging and then restoring power to the computer. Today, however, the computer just stared dumbly--much as we did, until we tested the power supply.

Thanks to everyone who took a look at this.
