Profile 5 Power problem

Hi,
I have a problem with my Gateway Profile 5, All-in-one.
Win XP Home.
Gateway service is not the best. They have now out-sources the Support
to MCP.
'Gateway - Professional Segment Acquisition by MPC'
(http://www.gateway.com/about/news_info/transition.php)

MCP!!
Problem is, MCP website does not work!!!

I had a problem with it three years ago when it would not Start UP.
I sent it back to Gateway and they returned it with a new Power Supply.

It works just fine except for one issue.
It uses an external power supply similar to a laptop system.
When I turn off the power to the power supply, ( Pull the plug and put
it back in or power failure) the computer will not restart when I press
the Power button.
I have discovered that if I disconnect the power supply from the
computer and then reconnect it to the computer with the power supply
plugged in and then press the power button, it will start up normally.
When I shut down, I have to leave the power supply plugged in and
powered up.
What is going on?
I have tried changing the “Power” settings in the BIOS and none of the
settings solve the problem.
It seems that there are other users that have had problems that are
similar. (but worse)
There is one odd feature.
After shutting down, about 12 seconds later, a message, “Power Save
Mode” pops up on the screen.
I have checked the Power Management settings and can find no reason for
this.
Is there some setting in the Power Management that is causing this?
That’s all the information on the problem.
I just will NOT send it back to Gateway for this.
IT TAKES TOO LONG.
I will just leave Gateway!!!
I have been fiddling with this for a long time.
Any ideas?
Joe
