XP power schemes all gone, can't control power options

I have not installed any software or hardware. Only automatic Windows updates and Office updates have been installed.  All of the Control Panel|Power Options|Power Schemes are gone or grayed out.  System insists on putting the monitor into "power save", though I don't want it to.  As a clue, during the period when things changed, many desktop icons changed their design, as if a new set of icons came with one of the automatic updates.

There's a command line option, powercfg.exe, that you can use to change power settings. If you open an ms-dos prompt and type "powercfg /?" It will give you a list of different things you can do, including changing the scheme or components within the scheme.
I would give that a shot.

That just brings up the same screen that comes up in the control panel --- with all the options grayed out.
Are you logged is as a local admin?
When I go to a command promp on a Windows XP machine and type "powercfg /?" I get this:

C:\Documents and Settings\xxxxxxx>powercfg /?
POWERCFG [/LIST | /QUERY [name] | /CREATE name | /DELETE name |
       /SETACTIVE name | /CHANGE name settings |
       /HIBERNATE {ON|OFF} | /EXPORT name [/FILE filename] |
       /IMPORT name [/FILE filename] | /GLOBALPOWERFLAG {ON|OFF} /OPTION flag |
       /BATTERYALARM {LOW|CRITICAL} [settings] |
       /DEVICEQUERY queryflags | /DEVICEENABLEWAKE devicename |
       /DEVICEDISABLEWAKE devicename | /?]
    This command line tool enables an administrator to control
    the power settings on a system.
Parameter List:
    /LIST, /L       Lists the names of existing power schemes.
    /QUERY, /Q      Displays the configuration of the specified power scheme.
                    If no name is specified, the configuration of the currently
                    active power scheme is displayed.
    /CREATE, /C     Creates a power scheme with the specified name.  The new
                    scheme is created with the properties of the currently
                    active scheme.
    /DELETE, /D     Deletes the power scheme with the specified name.
    /SETACTIVE, /S  Makes the power scheme with the specified name active.
    /CHANGE, /X     Changes settings of the specified power scheme. Additional
                    switches specify the changes as follows:
                        /monitor-timeout-ac <minutes>
                        /monitor-timeout-dc <minutes>
                        /disk-timeout-ac <minutes>
                        /disk-timeout-dc <minutes>
                        /standby-timeout-ac <minutes>
                        /standby-timeout-dc <minutes>
                        /hibernate-timeout-ac <minutes>
                        /hibernate-timeout-dc <minutes>
                        /processor-throttle-ac <throttle>
                        /processor-throttle-dc <throttle>
                    AC settings are used when the system is on AC power.
                    DC settings are used when the system is on battery power.
                    Setting a timeout to zero will disable the corresponding
                    timeout feature.  Supported throttle settings are NONE
                    CONSTANT, DEGRADE, and ADAPTIVE.
    /EXPORT, /E     Exports the power scheme with the specified name to a
                    file.  If no filename is specified, the default is
                    SCHEME.POW.  This additional parameter is supported:
                        /FILE <filename>
    /IMPORT, /I     Imports the power scheme from a file under the specified
                    name.  If no filename is specified, the default is
                    SCHEME.POW.  If a scheme with that name already exists, it
                    is replaced with the new one.  This additional parameter
                    is supported:
                        /FILE <filename>
    /HIBERNATE, /H {ON|OFF}  Enables/Disables the hibernate feature.  Hibernate
                    timeout is not supported on all systems.
    /NUMERICAL, /N  Allows the power scheme to be operated upon to be specified
                    using a numerical identifier.  When using this switch, in
                    place of the name of the power scheme on the command line,
                    specify its numerical identifier.  This switch may be used
                    in combination with the /QUERY, /DELETE, /SETACTIVE,
                    /CHANGE, /EXPORT, and /IMPORT commands.
    /GLOBALPOWERFLAG, /G {ON|OFF}  Turns one of the global power flags on/off.
                    Valid flags (to be used after "/OPTION ") are:
                         BATTERYICON:    Turns the battery meter icon in the
                                         system tray on/off.
                         MULTIBATTERY:   Turns on/off multiple battery display
                                         in system Power Meter.
                         RESUMEPASSWORD: Prompt for password on resuming the
                         WAKEONRING:     Turn on/off wake on ring support.
                         VIDEODIM:       Turn on/off support for dimming video
                                         display on battery power.
    /AVAILABLESLEEPSTATES, /A  Reports the sleep states available on the
                    system.  Attempts to report reasons why sleep states are
    /BATTERYALARM, /B {LOW|CRITICAL}  Configures the battery alarm.  The
                    following switches can be specified:
                        /activate <on|off>
                            Enables or disables the alarm.
                        /level <percentage (0 - 100)>
                            The alarm will be activated when the power level
                            reaches this percentage.
                        /text <on|off>
                            Turns the text notification on or off.
                        /sound <on|off>
                            Turns the audible notification on or off.
                        /action <none|shutdown|hibernate|standby>
                            Specifies the action to take when this alarm goes
                            off.  Not all actions are always available.
                        /forceaction <on|off>
                            Force stand by or shutdown even if a program stops
                        /program <on|off>
                            Specifies a program to run.  schtasks.exe /change
                           may be used to configure the program.
    /DEVICEQUERY <queryflags> will return a list of devices that meet the
                    criteria specified in <queryflags>.  Possible values
                    for <queryflags> are:

    POWERCFG /QUERY scheme
    POWERCFG /CHANGE scheme /monitor-timeout-dc 15
    POWERCFG /CHANGE scheme /monitor-timeout-dc 0
    POWERCFG /EXPORT scheme /file file
    POWERCFG /DEVICEENABLEWAKE "Microsoft USB IntelliMouse Explorer"

Open in new window

powercfg /create "Name Of Profile"
powercfg /setactive "Name Of Profile"
powercfg /change /monitor-timeout-ac 0
powercfg /change /monitor-timeout-dc 0
Does the monitor stay on? And is it set properly with the new Power Scheme?


It's uncommon but not unheard of for Malware to slip in with MS's updates. [Automatic or not.]
I've gotten a virus's on fresh installs that way twice.
Once back around 2004. Once in June 2009.

I get an error message for those commands "Windows cannot find [command]. Make sure you have typed it correctly."

Thanks anyway.
bwrubleAuthor Commented:
Entering powercfg/? from a DOS prompt gives me all that info, but it won't accept commands.  I get "unable to create new power scheme"  It seems that power schemes are files of the form *.pow  A search of the computer finds no *.pow files.
maybe time to run sfc /scannow, or a repair install :http://www.michaelstevenstech.com/XPrepairinstall.htm      
Try replacing powercfg.exe from a known good machine. Delete the WFP copy in c:\windows\system32\dllcache first.....
>> I get an error message for those commands "Windows cannot find [command]. Make sure you have typed it correctly." <<

Yes, that's -exactly- why I suggested what I did.
Malware often affects "start>run>cmd>whatever" in strange ways.

You are right, I was just interested in that single file. SFC often causes too many problems in just trying to get it to work, if your system has had a Service Pack installed, installed form a CDRom/HDD etc....
Thats why I was offering the single fix, and not all of them. Definately not trying to take away from the validity of your comment....
bwrubleAuthor Commented:
There is no folder "dllcache" in Windows\system32\

What is a "WFP copy"?
bwrubleAuthor Commented:
Installing clean powercfg.exe made no difference
Have you tried the site I listed in the beginning?
bwrubleAuthor Commented:
Not yet.  i found it a little scary and a little hard to figure out.
All you have to do is go to the kelly's corner site that it is referencing and do a search for your issue. Just type in "Power" and navigate thorugh until you see the right one. Click on that file and save it. The instructions for what to do with the file are located at the top of the site.
