Hello budy,
Thanks for your question.
Gateway, for one is aware of this problem as noted on this page:
http://support.gateway.com/s/issues/662931010.shtml
"Keyboard Driver Prevents Windows From Entering Standby and the Mouse
Pointer Disappears
ISSUE: In Microsoft® Windows®, the following error message may appear:
"The device driver for the Millennium PS/2 keyboard device is
preventing the machine from entering standby, please close all
applications and try again. If the problem persists, you may need to
update this driver." Also, the message may reference the Standard
101/102 or Microsoft PS/2 natural keyboard driver if the Millennium
PS/2 keyboard driver is removed. After this error occurs, the mouse
pointer disappears.
RESOLUTION: Remove the program that is causing the issue, and then
contact the vendor to see if an updated version of the program that
does not cause this issue in Windows XP is available. Use the
following instructions to access Add or Remove Programs..."
You can read the rest for simple instruction on removing the program,
however, Gateway never mentions WHICH program to remove. In checking
my own machine, it would be the IBM Rapid Access keyboard. You should
find reference to a keyboard program in your add and remove programs
control panel.
You do not mention what operating system you are using. Gateway refers
to XP in this page, and it is likely that if you are using XP either
your keyboard device or the program you run when you get this error
message requires updating to be XP compatible.
Standby Issues at Kelly's Korner has several articles that discuss
standby issues with different hardware components. Most mention video
cards and drivers, but you might look here to see if any of the
devices mentioned are devices in your system::

You will also find a good page on troubleshooting if you happen to be
using Windows ME here:

I then searched Microsoft's Knowledgebase for - preventing the machine
from entering standby - and found several articles:

Device Driver Error Message Is Generated When the Computer Enters
Standby or Hibernate Mode
CAUSE
This behavior can occur if a program installs a kernel-mode driver
that attaches itself to the standard keyboard driver (I8042prt.sys)
and does not support Plug and Play I/O request packets (IRPs).
Examples of programs that exhibit this behavior include:
Pgpdisk version 6.02 and 6.5 (installs Pgpmemlock.sys and Pgpdisk.sys
drivers)
Adobe Type Manager version 4.0 (installs the Atmhelpr.sys driver)
RESOLUTION
To resolve the behavior, contact the manufacturer of your program to
inquire about the availability of an updated version of the program
that is designed for use with Windows XP.
To work around this behavior, uninstall the program that causes this
behavior, and then restart your computer.
And another for Windows 2000:

Device Driver Error Message Is Displayed When the Computer Enters
Standby or Hibernate Mode
With the same basic article text as above.

Unable to Use Power Management Features
SYMPTOMS
When you try to use power management features such as Standby or
Hibernate, your computer may not enter the power management state that
you choose, and you may experience one or more of the following
symptoms:
Your mouse may stop responding.
You may be unable to open or use the Power Options tool in Control
Panel.
You may receive the following error message:
The device driver for the device name is preventing the machine from
entering Standby or Hibernation. Please close all applications and try
again. If the problem persists, you may need to update the driver.
CAUSE
This issue can occur if you are using one or more device drivers that
do not implement power management functionality correctly because they
are not Plug and Play or power management enabled.
RESOLUTION
To resolve this issue, contact the manufacturer of the driver to
inquire about the availability of a driver that correctly implements
power management functionality.
To work around this issue, use any of the following methods:
Uninstall the Driver
You can uninstall the driver that is associated with the device that
is specified in the error message. For information about how to do so,
view the documentation that is included with the appropriate device.
Quit Any Programs that Interfere with Power Management Functionality
If you can determine which programs interfere with power management
functionality, you can quit these programs before you try to use power
management features. Note that some third-party programs that are
associated with imaging devices (such as scanners and cameras) may be
more likely to interfere with power management functionality.
******************************************
So, either the driver for your keyboard itself or another program or
hardware device such as mentioned above needs to have an updated
driver installed for you to regain this function.
Some helpful information to have on hand would be:
Which operating system are you using?
Did you just upgrade your operating system?
How long have you had this problem?
Have you recently installed new hardware or software just prior to
this message starting?
What keyboard are you using?
Did you install specific drivers for this keyboard in the past?
What video card are you using?
Are you using any particular program when you receive this error
message?
Virtually every tech support article for this issue echoes the above
solutions of updating either your keyboard driver or updating another
program that has installed a non-compatible driver to your system.
Answering the above questions and reading the articles I have provided
should most likely help you to isolate and correct the problem.
Here are a few more links for similar error messages for specific
hardware components that might inform you a little more about these
type of driver problems and conflicts:

Standby and hibernate modes won't work in Windows XP - and an "Unknown
device" is reported at startup
Problem
You upgraded your IBM desktop computer from Windows 98 SE to Windows
XP Home Edition. Before upgrading you followed Microsoft's advice, and
reflashed the BIOS with the latest XP-compliant update, and downloaded
the relevant XP device drivers for the system's devices and
peripherals from IBM's website.
Everything installed properly, but a mysterious "unknown device" keeps
being recognised at startup, and whenever you try using the standby
and hibernate modes the following message comes up:
"The device driver for the 'PC/AT Enhanced PS/2 Keyboard (101/102-Key'
is preventing the machine form entering hibernation. Please close all
applications and try again. If this problem persists, you may need to
update this driver."
XP's Device Manager reports that the keyboard is using the XP driver,
and that there is no update available. You want to know how to make
the hibernate and standby modes work.
Possible solutions
As is often still the case, the error message is misleading. The
device driver for the keyboard is not at fault here, so even if an
update is available, it won't help.
The problem is caused by third-party software that has installed a
kernel-mode device driver, which has attached itself to the
18042prt.sys keyboard driver - and it is not compatible with XP. The
most common culprit is Adobe Type Manager 4.0 (ATM), which installs
the Atmhelpr.sys driver.
As a temporary fix, either uninstall ATM, or use Find, and rename the
offending file Atmhelpr.xxx. Doing that disables ATM's font-smoothing
effect. If you want to use font-smoothing, you can enable XP's
version.
Note that other third-party software can cause the same problem. That
is why it is always best to do a clean installation of a new operating
system instead of upgrading from one operating system to its
successor, because the upgrade doesn't allow you to install and test
each piece of software on its own. The upgrading process merely
rebuilds the Registry around the installed software, and therefore
leaves much of the old operating system in place when it should be
removed. "
The rest of this article deals with registry entries. If you are
comfortable working in the registry, you might try their additional
tips and solutions. Do make a backup copy of your registry first.
I hope the above has shed some light on your problem and helps you
target the exact culprit. Do ask for clarification if needed.
