Method 1: Use the Powercfg.exe utility to restore the default power scheme

You can use the Powercfg.exe utility to copy the power scheme from the Default Userprofile to the user who is currently logged on. You can do this because power schemes are uniquely associated with individual user accounts. To copy the power scheme from the default user by using the Powercfg.exe utility, follow these steps:

Click Start, click Run, type cmd, and then click OK.
At the command prompt, type the following command, and then press ENTER:
powercfg /RestoreDefaultPolicies

Method 2: Use the Powercfg.exe utility to import a power scheme from another Windows XP installation.

You can use the Powercfg.exe utility to export power schemes from a parallel Windows XP installation or from another Windows XP computer and to import to the original Windows XP installation. To do this, follow these steps:

On a new parallel installation of Windows XP, or on another Windows XP computer, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command, and then press ENTER:
  powercfg /export scheme /file file
  Note In this command, scheme represents the power scheme that you want to save. Also, file represents the path of the file name with which you want to save the power scheme. In the current scenario, save the file to the location where the original Windows XP installation files are saved.
On the original Windows XP installation, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command, and press ENTER:
  powercfg /import scheme /file file
  Note In this command, scheme represents the power scheme that you want to import. Also, file represents the file name for the power scheme. In the current scenario, specify this file as the file that you saved earlier in this procedure.
Repeat all the previous steps if you want to export and import more power schemes.
Verify that the power schemes that you imported are now available on the Power Schemes tab.
