sorry, we must have crossed there. If you turn off the power management (i.e. set it to "always on", there are no problems?

If no, how is the PM feature configured?

Is the OS configured to take FULL advantage of ACPI? I mean you can power down  the system totally by software only without having to push the power button?

You can check this using device manager > system devices and look for word ACPI in the devices listed. If it is listed then ACPI modules are implemented.

Now again, lockups, what do you mean exactly? Your PC won't come up again from system standby or system suspend?

I forgot to mention about a feature included with windows 98 that enables you to trouble shoot power management failure.

And also, the reason I ask if ACPI is installed, is that there are two kinds of power management, ACPI and APM... the first one being the most efficient, but proves to be most erratic if not properly implemented by any of the devices in your PC.

I had power management problems with Windows 98 too.  After I got a BIOS flash upgrade from the motherboard manufacturer's web site, most of my problems went away.  

If your BIOS supports it, have a power management "break event" enabled for the IRQ your modem is on.  If your modem is in use (including waiting for a fax or voicemail call) when power management tries to engage, Windows usually tells you that it was unable to suspend the machine.  Enabling this break event prevents Windows from trying and therefore gets rid of some potential problems.

This question was awarded, but never cleared due to the JSP-500 errors of that time.  It was "stuck" against userID -1 versus the intended expert whom you awarded.  This corrects the problem and the expert will now receive these points; points verified.
